Car Forum / Ford / Ford Trucks / September 2008Need Help with P0320 code
Hello, I need help with a problem I am having. I was driving on the highway and the truck started to sputter and stalled. I was able to start it but it stalled again when I started to go. After clooling down (via the tow home) It started again but after a short time it stalled again like someone turned it off. Next morning it started and ran normal for about 20 minutes, (It seemed to hit a rev limiter at 3000 RPM) then same thing but this time a code regestered. P0320 Ignition Engine Speed (PIP) Input circuit fault Does any one know what could cause this? Thanks any help is appriciated. Joe > Hello, > I need help with a problem I am having.

Yeah. Sure. Or, maybe the distributor has disappeared. >>> And what might that be? >> [quoted text clipped - 11 lines] > > Yeah. Sure. Or, maybe the distributor has disappeared. Well, I'm sure you realize that the distributor doesn't fire the spark plugs anymore, but there's still a need to tell the computer what the crank and cam angles are. The cam angle is an unknown, that's where I'd be looking for the solution to the P0320 Code. For lack of a better word, it's reasonable to call that device a distributor. Granted, there is a better word, but I don't see it as particularily helpful. My F150 with the 4.6L motor has two of them. Well, I also have spark plug wires coming out of them. I could look at my BMW and describe the location of the non-existant distributor, but somehow I don't think it would help you. >>>> And what might that be? >>> [quoted text clipped - 23 lines] > my BMW and describe the location of the non-existant distributor, but > somehow I don't think it would help you. What you're calling the distributor is nothing but an ignition coil. It does not contain the functions of a distributor (picking up camshaft position data and signaling the ignition coil to fire). Both of those functions are provided by the engine management computer, and the accompanying crankshaft and camshaft position sensors, which is most likely the source of the OP's problem. >>>>> And what might that be? >>>> [quoted text clipped - 27 lines] > It does not contain the functions of a distributor (picking up camshaft > position data and signaling the ignition coil to fire). Bingo!

There is a crank position sensor AND a cam position sensor. Think of the job previously handled by the distributor when you are thinking cam position. The crank position sensor has it's own code that specifically defines the crank position as the problem. >>>>>> And what might that be? >>>>> [quoted text clipped - 29 lines] > > Bingo!

There is still a device that collects this data, even if it does not look like what you expect a distributor to look like.

The point is, the trouble is with the parts that live in the space once occupied by the points, which became a magnetic pick-up before it became the engine speed sensor that fails and gives a P0320 code. >>> Hello, >>> I need help with a problem I am having.

Any instance of P0320 will be caused by the same thing. > > What if it has a distributorless ignition? If there is no device to cause the code, then the code can not come up. That's a big part of why there was a change from OBD I to OBD II. Under OBD I, consumers were being raked over the coals and bent over the barrel by mechanics that claimed they were forced to attend specialized schools for each make and model of car they worked on. Each one had differing means of extracting codes, and differing definition of what the codes meant, and so on and so forth. Under OBD II, the codes were standardized, the location of the data collection points were standardized, the means of extracting the data was standardized. Part of the standardizatioin is that a code means the same thing across all vehicles that can produce it, and any vehicle that hasn't got the components to cause a particular failure will never produce the error code associated with that failure. Therefore, if there is a code that defines the loss of a timing signal, then there must be a component that tells the engine computer that there is a timing signal that has gonen away. My vote remains the distributor, or whatever you wish to call the device that fills that void. Sorry about that. 2004 4L 4WD Ranger >> Hello, >> I need help with a problem I am having.
