hi guys,

i am just a tourist on this ng, but hoping to get some advise. i
recently bought a 06 Scion Xa and within a few days the check engine
light came on with 5 evap system codes.  the car has just 18k miles ,
p.o. got it jan 16 06.  i now see that consumer reports saya there is a
problem with the fuel system with 06 Xa's so i wonder where i should be
looking, ( i tried the filler cap and reset the codes once).

thanks for any constructive comments,
peter in CT

What was the original date of sale? Many emission system components
have a longer warranty than the basic warranty (see your owner's
guide). The dealer should be able to tell you whether or not your car
is still covered. The original warranty transfers with the car, so
there is a good chance a problem with the emissions system is covered.

Emissions systems are warranteed for, IIRC 10 years. I would bring it to
the dealer.

The original warranty was 3 years/36,000 miles. Like CE said, check the
original date of purchase.

Also, if the car was bought by you from a dealer and was a "Certified
Used...er, Toyota..." there should be an extended warranty that came with
it. It has to have been a Certified Used Toyota, or, if the original
ourchaser bought the extended warranty package then it is transferrable
to you.

Check this out. 18,000 miles is not a lot of miles to be throwing codes...
peter - 02 May 2008 23:31 GMT
hi,
the codes i get are:

P2043E Evap Sys Leak Orifice Low Flow
P2043F Evap Sys Leak Orifice Hi  Flow
P2401  Evap Sys Leak Circuit Low
P2402  Evap Sys Leak Circuit High
P2419  Evap Sys Switching Valve Circuit Low

the dealer said it would be a $92.50 diag charge, (even if it is a
warranty issue? Oh, no, not then).  they said it is the charcoal
canister and filler neck (that seems odd but...)  so next week they will
have the pats and "fix" it under warranty i wonder why this happened and
if there is any way to prevent a re-occurrence?

thanks peter

Those codes are not valid.

Check this link out ...
http://autorepair.about.com/od/obdcodedatabase/a/OBD_1996_year.htm

Does the Check light come back on again after being reset?

The Evap System is the system that controls gas fumes that were formerly
vented to the atmosphere long ago. The system is supposed to be sealed
(closed), but is obviously opened whenever gasoline is pumped into the tank.
It has been found that most evap system errors are rooted in the gas cap not
installed completely. There are other things that can cause leaks, but the
gas cap can be caused and corrected by the vehicle operator, and I would
suggest that before a dime is spent on service diagnosis, a few extra
seconds to make sure the gas cap is seated well is worth the cost.

The codes you gave are not valid for the ODB II system, and a valid Evap
System error code would be in the range of P0440 to P0456, or something
close to that.

The codes do not change. Some can be added as time goes on, that is
certainly true. But the Evap System codes have been thoroughly defined, and
no new codes are needed, making the codes you listed more suspect than the
link I gave.

That's a good thing to do. It's certainly a similar kind of problem. As a
practical matter, yoiu probably can't look very closely at the filler neck
because much (if not all) of it is hidden.

The cause of the check engine light is not a loose gas cap.  The charcoal
canister traps the evaporative emissions (gas fumes) and stores the fumes
for the engine to burn.  There is a hose between the charcoal canister in
the engine compartment and the fuel filler neck, and I think this problem
has cropped up before.  The replacement parts should cure the problem, but
to be sure, try to avoid topping of the tank.  Constantly topping off the
tank can contaminate the charcoal canister.

A loose gas cap will give a different set of trouble codes.  The codes you
listed are Toyota-specific codes.

Do you know what the rationale would be for unique codes for this? There is
already a wealth of Evap System Error Codes, and problems that exist with
the canister would also exist on other auto maker's products so this should
not be a unique system.

A major reason for OBD II was that OBD I used different codes for the same
problem from different auto makers, ie; a fouled plug gave a different code
for every auto maker, and technicians were found to charge the customer for
the education to learn the various codes, and of course there was different
different diagnostic equipment required as well that generated charges to
the consumer. If Toyota uses unique codes for a common problem, this seems
like a giant step backwards.

The intent of the OBD II protocol was to standardize the diagnostic
interface for all automakers, i.e., diagnostic connector configuration,
software that interprets trouble areas, and the diagnostic trouble codes
(DTC) for components that are common to most or all vehicles.  The OBD II
protocol allows for manufacturer-specific codes if the manufacturer does
things in a unique way or monitors a component that not all vehicles have,
like a traction control system.

I said above that the number 2 is for manufacturer-specific codes, but that
was incorrect.  I think the numbers the OP listed are warranty operations
codes and not DTC's.  Dealers have to use the manufacturer's warranty
operations codes to get paid for warranty repairs.  I'm not sure if the
warranty coding system is still the same, but dealers used to have to list 3
codes for a warranty repair:  T-1 was a description of what the car was
doing or condition; T-2 is the cause of the condition; and T-3 is what the
dealer did to resolve the condition.  The codes the OP listed look like T-2
codes to me.

Okay, that makes sense. I would expect the Evap System codes to be in the
range of P0440 to P0459, or something like that. If the codes the OP gave us
were Warranty Codes, or codes specifically pulled by Toyota but not sourced
in OBD, then they could easily be as he stated. They are Toyota Codes, but
not OBD Codes. That makes sense.

I'd like to call you on one very fine point though. OBD II did standardize
codes and connections for auto makers, but the intent was to make it so the
consumer would not have to pay for the myriad test equipment needed by
service centers to accomplish a relatively routine service call. If a guy
with a Ford and a guy with a Chevy showed up on the same day with the same
problem at the same service center, the technician would need two different
diagnostic tools to figure out the problem, and would bill for the education
and for the equipment needed to do the automotive equivelent of getting the
pulse and blood pressure from the vehicle. Consumers were getting hosed
under OBD I, and OBD II standardized this operation to the benefit of the
consumer. The auto industry complies because they are told to, not because
it makes life easier for them. Make no mistake, OBD II is intended to
benefit the consumer, not the industry.

I don't actually *know* the rationale for standardizing the OBD II system,
but I do know that it is an SAE standard.  I haven't kept up my membership
in the SAE, but they weren't a consumer advocacy group back when I was a
member, and I doubt that they are now.  The SAE, being a group of engineers,
does like to have things standardized as engineers often do.    The
automakers benefit from the standard because much of the research and
engineering is already done for them.

From my experience in the car business, my guess is that the independent
service industry lobbied the SAE for one interface that they could buy,
instead of having to purchase several different scanners while the auto
dealer service departments could get away with scanners just for their
brands.  Of course, the independent service industry is going to say that it
helps the consumer because the independent shops give the dealers
competition, and competition is good for the consumer.  I agree with the
principle behind having a standardized interface and that competition is
good for the consumer, but what I've noticed is that many independent shops
lack the diagnostic skills to interpret the DTC's and just swap the
component identified by the DTC instead of checking the component's
function.  Dealers send their technicians to factory classes so that they
keep current with the technology in vehicles and also learn how to properly
diagnose and repair various conditions.  Many independent shops do not send
their employees to continuing education, as evidenced by their low success
rate in diagnosing anything other than a simple component swap.  IOW, what
should have been a good thing by having a standard DTC and interface hasn't
quite come to fruition.

The independent service industry is lobbying lawmakers for "right to repair"
laws where automakers have to make proprietary information available to
them, in addition to the factory service manuals that are already available.
The automakers' counter to this argument is that they invested a lot of
time, money, and resources to develop, test, and produce the proprietary
information and that they should be able to keep it to themselves just like
anything that someone in any other industry would be able to do.  I tend to
agree.  Just because an I pod is wildly popular doesn't mean that Apple has
to license their design to anyone who wants it.

The OBD I standard came out of SAE too.

Granted, the independent service community was overwhelmed by the various
iterations of implementation of the OBD I system, they charged a service fee
for the trouble it caused them. My understanding is that OBD II is
consumer-driven. Obvious benefactors are the service providers, but they
charged fees for the problems caused by OBD I, so they were not really
motivated to change out of the OBD I system.

The consumer was met with insurmountable issues with some implementations of
OBD I, and OBD II gave us a data scheme that could be learned and would
easily transfer from one car to the next that we had parked in the driveway.
In the OBD I world, I had to have a different scan tool for every car I
owned, in the OBD II world, the same scan tool works on all of the cars I
own.

Technically, there was no OBD I standard.  Each automaker had their own
proprietary diagnostic system and codes.  You didn't even need a code
scanner to pull codes from a Toyota OBD I system.  All you needed was a
paper clip to short the check terminals.  The lack of a standard was the
reason for OBD II.

Service facilities charged a service fee to pull trouble codes from OBD I
systems because most consusmers couldn't figure out how to pull them and so
they were willing to pay a fee.  The easy availability and use of OBD II
scanners have made people less willing to pay a fee, and so the market place
has started to move away from fees to just plug a scanner in.

I have not tried to pull OBD I codes from a vehicle other than a Toyota, but
Toyota's scheme seemed pretty easy to me.  The codes were consistent from
Toyota to Toyota, and a paper clip cost a lot less than even the cheapest
OBD II scanner.  The method for checking components identified by the DTC's
haven't changed.  The only drawback I see with Toyota's OBD I system is that
it was not as comprehensive as OBD II, and the codes are not published in as
many web pages as OBD II.

They were not so willing as they had no other choice. There was no published
standard that said to fully depress the gas pedal 5 times, or turn the
igniiton on and off 5 times ending in the on cycle, or short two pins
together, or stand on your head and spit wooden nickles and while twisting
the rear view mirror counterclockwise as you pop the trunk latch and set the
igniton to on, all at the same time. And the hoops to jump through for one
car were different than for another.

Of course the codes were consistant from one Toyota to the next, but Toyota
built products that had the Chevy nameplate on them, and these were
different than the rest of the Chevys.

My Jeep has to turn the ignition off and on while holding your tongue to the
left side of your mouth. My BMW requires mashing the gas pedal 5 times while
holding your tongue against the right side of your mouth. My Ford wanted a
scan tool connected to the right place while spitting wooden nickels. I have
a Mazda that I have not figured out how the codes come out -- I'm pretty
sure I don't hold my tongue in the correct orientation. You have Toyotas
that want a paper clip inserted into the right front turn signal socket
while dancing a jig.

It should be easy to see why a service center would charge to pull codes.
Once they get the codes to come out, whatever the code is is different from
one car to the next, that's an extra charge.

"We pull codes for $25.00. For another $50.00, we'll tell you what they
mean. If somebody else fixes it, that's $25.00 more.

You can see how the consumer was over the barrel with OBD I.

I don't know why the folks who designed the OBD systems on your Jeep, BMW,
Ford, and Mazda made you go through such contortions when shorting a couple
of connectors was such a simple solution.  I'm not disputing that consumers
can benefit greatly from OBD II, I'm just saying that is a side benefit that
resulted from the requirement for tighter emissions monitoring and
standardization.

Now that I think about it, OBD II was the SAE's response to stricter
emissions requirements while making it easier for emissions test stations to
check more of the components that affect emissions that might not show up on
a sniffer test.  The standardization was a result of emissions regulations,
not because of any great concern for the consumer on the part of the SAE.

OBD II does make it easier for consumers and shade tree mechanics to pull
trouble codes, but I'm not so sure that consumers and shade tree mechanics
can even identify some of the components listed in the trouble codes, and
even fewer would know how to test the component to see if it is actually bad
or not.  Merely replacing the identified component is an amateur approach to
diagnosis that is no guarantee of success.

For example, a friend's Windstar had a check engine light come on and yes,
being able to use my handy dandy OBD II scanner instead of needing to buy a
Ford specific scanner and do a jig was convenient.  DTC's P0171 and P0174 -
system too lean Bank 1 and Bank 2 came up.  What do you think the fix was?
In the interest of full disclosure, I called a friend who is a Ford master
tech instead of checking voltages and resistance on a lot of components that
I wouldn't know the correct values for anyway.

In the order of frequency that I see;

2) intake manifold gaskets leaking
3) MAF sensor failed/contaminated
4) IMRC seals leaking
5) both O2 sensors shorted

Here in Tejas they don't even sniff my 05 corolla for emissions.
Totally OBD II tested.. So that makes sense..

It wouldn't surprise me if the OP's car has had the gas tank
filled to the brim, or overflowed in the recent past.
That happened to mine, and it eventually dried out and fixed
itself. Ditto for the OBD II.. I let it clear itself.. I never reset
it
after all that happened.
I recently had it inspected and it flew through without a hitch.
So I assume the data from the evap problem has long since
been purged. Seems like it takes about 40 cycles or so
I think, but I fergot.. It had a few months to overwrite the old
stuff...

Vehicles with OBD II are tested via OBD II, while non-OBD II vehicles are
usually sniffed.

It takes 2 cycles without a fault to purge the memory for an OBD II vehicle.

I was thinking it was about that many for each part
being tested, but I was thinking there was a overall "history"
being written separately, that took more cycles to purge,
but maybe not.. It's been a while since I read up on OBD II
so I'm getting kinda foggy on it.
At one time I thought about getting a scanner, but with the
autozone nearby doing it for free, I couldn't see the point in
wasting the money.
I'm pretty sure a car with OBD II freshly reset will fail the test
here.
It has to run through a few cycles before you take it in for the test.

That is the way it is in NJ anyway.  If you reset the OBDII by pulling the
fuse it wipes the memory but leaves a 'not ready' situation when read by the
inspection station.  I tried to slime my way through with the Sienna that
way to avoid them picking up a code and I failed because of that 'not ready'
situation.

Most, but not all, components monitored by an OBD II electronic control
module (ECM) have a 2-trip detection logic, where the ECM has to see the
problem on 2 consecutive trips before it illuminates the malfunction
indicator light (MIL).    An example of a component that does not have 2
trip detection logic would be a knock sensor.  If the ECM does not see a
signal from the knock sensor, it will retard the timing the maximum amount
because constant knocking can damage the engine.

For components with 2 trip detection logic, the ECM records either a good or
bad signal for 2 trips.  If the memory is cleared, the memory locations for
the component are empty and are neither good or bad and so the ECM indicates
that it is not ready yet because it has not gone through the 2 trips
necessary to fill the memory locations.  There is no additional "history"
beyond the last 2 trips, which is why you get the "not ready" status until
the 2 trips have occurred.

There are specific parameters for the ECM to count a driving session as a
"trip."  Basically, the engine, coolant, O2 sensors, and catalytic converter
have to reach operating temperature and all of the sensors have to have a
chance to sense whatever it is that they are supposed to be sensing.   For
example, just starting the car and letting it warm up won't let the vehicle
speed sensor sense how fast the vehicle is moving.  The factory repair
manual has a list of conditions that have to occur before a driving session
qualifies as a trip.

There was no published standard because there was no standard.
The service procedures fro extracting codes certainly were published in
numerous ways by numerous entities.

What product did Toyota build that had a Chevy name plate?

Nope.

Nope.

Nope.

It has nothing to do with your tongue.

Nope.

It should be easy to see why Starbucks charges for a cup of coffee.

Rubbish.

Perfectly fair.

Yes, the cost of a paper clip certainly put them over a barrel.

There is no such thing

OBD2 is not an SAE standard, it is an EPA emissions standard.
Within that standard are SAE defined communication protocols, defined
DLC shape and defined DLC pin configurations.

Not true.

They charged a service fee for the time it took and the service they
provided.  Still do.

You understand wrong.
The EPA criteria for OBD 2 is that the MIL be illuminated when the
system detects that emissions are exceeding federal standards by a
factor of 1.5

The same scan tool does some stuff on all the cars you own.
Different (multiple) scan tools are still a necessity for truly
effective repairs.

I guess that is one reason we see so many Scions on the used car lots of
other brands.

What error code did you get?

What did you do to reset the codes?

Your car is OBD II compliant, this means you can use the scan tool to
extract the codes and reset them, instead of resetting them by disconnecting
the battery and never what threw the code in the first place.

Visit your local Autozone store where they will either pull the codes for
you or give you the scan tool so you can pull them yourself. The data port
is in the foot well along the bottom edge of the dashboard. It is typically
found between the outer bulkhead and the steering column, generally in the
area above the clutch pedal whether or not you actually have a clutch pedal.

The directions are on the scan tool for pulling codes and erasing them.

Toyota/Scion warrants the vehicle, not the owner.  If the vehicle is within
the 36 month, 36,000 miles warranty period, diagnosis and repair should be
covered.  The emissions warranty coverage period is even longer, so chances
are, you can get the problem fixes.
