Replaced sensor, same problem.

I was doing some other work at this shop as they were swapping the motor out in this F When they got done they had a p Bank 1 Cam code, This is a complete rebuilt Jasper motor. They double checked everything they had done several times and asked me to look at it. I saw it had new pigtails on the bank 1 and bank 2 cam sensors, they state were there before they got the vehicle. I checked grounds and signals coming out of the sensors, Put my scope on both sensors, and crank sensor. I show up today to do the security for the PCM, and after keys are learned I checked codes and P and P are pending on start up. I start over from scratch.

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.

Send a private message to fastford I didn't do an in cylinder because if they were off I'd see it on the cam timing. Posting Quick Reply - Please Wait.

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.

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:. One common cause of the P code in your Ford F is a defective camshaft position sensor.

From until , the Ford F was powered by the 5. However, despite its good reputation, you should be aware of some 5. This engine fault code is related to a camshaft sensor but can be caused by several things other than the sensor, making it sometimes difficult to diagnose. This guide is going to discuss what the P code is, what causes it, and how to repair it. In , Ford changed the 5. Since the earlier models only have one camshaft, there is only one sensor.

I have also heard that a bad diode in the alternator can cause noise setting a code , though the alternator will still keep the battery somewhat charged. The Oil pressure is fine as well, just no way to monitor it at the front of Bank one. Was this information useful?

P and P with some helpful information about camshaft position sensors.

My son is going through the same thing with his '05 F 5. Read more about Ford and the error code P Does that sound possible or is there any other way to test it? Premium or no? Would you suggest hooking them up differently? It also doesn't ever rattle like the tensioners are failing. When I smoke the motor smoke comes out of my Egr and iac Ford F 5. One thing that threw me off was no bank 2 codes. The time now is AM. Find all posts by Kdawg He's so upset It's absolutely obvious on the scope that it's showing out of time now, and runs like it's out of time since It's throwing fuel and spark at the wrong time. Thanks all so much. Looking at your reversed waveform, if I invert channel B Red then I get a capture that matches my known good to within 3 crankshaft degrees.
