P and intermittent rough idle. Thread Tools. Hi, My friend just bought a F 5. Most of the time it runs great, but sometimes when you stop the truck the idle will drop down and the truck sounds like it is going to die but so far it hasn't actually died, it starts knocking really badly and runs very rough. If you let it keep running like that it sets P If you rev the truck up it cleans up and sounds fine again and it will even drop back down to a clean idle most of the time. I swapped the cam sensors because it was easy and just to see and it didn't make a difference, I was hoping after switching the sensors the code would switch to the other head but it didn't. Any thoughts? View Public Profile. Find all posts by Kdawg I am thinking probably bad VCT solenoid. I have both cam sensors unplugged and so far it hasn't had any issues since.. I am thinking this points to VCT solenoid. Does that sound possible or is there any other way to test it? Unfortunately since it is an 08 the valve covers have to come off to change the solenoids.

The error code P signals that there is a problem with the circuit of the camshaft position sensor. This sensor determines the rotational speed and the camshaft position , and then it sends this information to the PCM. With this information, the PCM synchronizes the timing of the fuel injection with the timing of the ignition system the spark. When the signal between the sensor and the PCM is interrupted, this synchronization fails and the engine may behave erratically. Search your problem. Search Log in Sign up. Have you found an error in this guide?

One of the more common engine management trouble codes that can occur in the Ford F is P P is related to the camshaft position sensor and points to an issue with the wiring harness connected to the sensor. This error can arise from a failure, defect, or malfunction in the control, signal, or reference voltage circuit s of the position sensor connected to the intake camshaft. It is crucial to address this issue promptly since it can potentially lead to further complications in your vehicle. The causes of P in the Ford F can vary and go beyond the camshaft position sensor itself. Some possible causes include:.

We recommend Torque Pro. This article will therefore deal with code P as it applies specifically to Ford vehicles. While several details of the ignition systems on Ford vehicles differ somewhat from the ignition systems of some other vehicle brands, Ford ignition systems are not so radically different from other systems that they are problematic, or difficult to diagnose.

Engine and body grounds. He hasn't even put miles on it and just had to replace his tranny and now this is happening. If you replace them and still have the issue, then most of the time it is an oil pressure issue. At this point I've been there the better part of a day going over this thing and coming up short.

If you let it keep running like that it sets P Verify all connections, make sure the connectors are pinned correctly. Per Daryl's statement that the waveform was backwards and Ray's waveform I depinned both cam sensor connections connectors and swapped them.
