Hi folks,
I am finally getting around to changing out that bad O2 sensor, and boy
it is so easy I cannot believe that I waited so long.  It is as right up
front as anything can be.

Wait, wait...  We have a problem.  The electrical plug.  I can't get the
darn thing to detach.  There must be a trick.

Can someone please tell me the trick?

Thanks,
Tomes

Should just be a squeeze and pull.

Or, perhaps it's a lift and pull. In that case you stick a screwdriver
into the slot, lift the tab and pull. Some of the underhood ones are like
that.

How ya been? Still lurking, I see!  ;)

I'll try squeezing it a few more creative ways.  I'm going out to it soon...

Been OK here.  Summer vacation now so I am doing a load of stuff that is
on the old to do list (like fix the Sienna finally).  The band is
practicing a lot lately as we have an important gig on 8/1.  I am always
around....   ;)

I got it off.  It was a lift and pull.  Sometimes I just gotta walk away
and come back and things become obvious.

Anyways, It is really, really strange driving the Sienna with no orange
lights at all lit up on the dash.  The tires all have the right air, I
put stuff into the windshield washer bin to turn that off, and no CEL,
at least not yet.  Almost creepy, as at night now the only thing lit is
one itty bitty bulb behind the speedometer.  I never realized how
comforting those orange lights were.

How may trips does one need to take before all the computing is reset
and I can get it inspected?

Somewhere around 5 or over 100 miles.

I have a Mazda that has the automatic shoulder belts. If it isn't
connected I get a red light on the dash.

I also have an "Upshift" indicator. Well, actually, it's the Washer Fluid
warning light, but when the washer fluid is at a certain level, it goes
out on acceleration and comes back on when it's time to shift...  ;)

So, I clamped the seatbelt in place, and filled the reservior. The
dashboard is a lonely place now...

Beats when I was delivering newspapers. I wanted to SEE the odometer, so I
removed the pleasant green bulbs and replaced them with the highest
wattage bulbs I could find. It was *BRIGHT* !!!!!

But, the pleasant green ones are back in...

If you go to rec.autos.tech, see my questions about a '95 Chrysler Town
and Country I ran across. Had what appear to be serious issues, and the
wanted $995. I offered $400. Especially after I noticed the black tape
over the 'Information Center' covering up the BRAKE! and ABS warning
lights...

They moved it to the back. They either sold it to someone who REALLY knows
these vans and knows what he's in for, or they're scrapping it...

You had to STAND on the brakes to get it to stop...

If the check engine lights are not illuminated and you did not pull the fuse
or clear the OBD II codes with a scanner, you are set to go.  If  you
cleared the codes with a scan tool or if you pulled the fuse, it will take 2
complete drive cycles.

Yep, I cleared the code with the scanner tool.  I took a round trip that
included a 7 mile run, a stop with it turned off for about 3 minutes,
then a return home.  Dunno if that is considered one or two drive cycles....

Basically, a "drive cycle" is where every sensor gets activated or warmed up
(with the exception of the knock sensors), the engine and O2 sensors get
warmed up, the engine goes into closed loop operation, and the transmission
shifts through every gear and lockup.  You'll want to get the vehicle up to
45 MPH or higher and cruise for a while as well.

OK. Sounds like I did all this twice in that trip.
Thanks,
