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. Verify all connections, make sure the connectors are pinned correctly. Engine and body grounds. Disconnect alternator completely. Follow the code trouble tree and it leads me back to replacing the PCM. Load test the wires, verify continuity, even unplugging coils 2 at a time to see if there was some noise that was interfering with things since i saw a mild triple strike in the waverform. Clear codes and check every time and as soon as I start it, codes return, pending.

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.
