Re: bad cam or sensor
Check this out.. The cam sensor wires and the Ignition coil wires CAN interchange.. If you reverse them.. It'll blow the ecm.. In other words.. you can plug the coil into the cam sensor by mistake.... Look into that.. thank you

Neither have anything to do with each other. The cam sensor is used to fire the injectors. The O2 sensors is for fuel mileage and to monitor the catalytic converter. If the O2 sensor is bad it will throw O2 codes and maybe a cat code (420). If the cat is bad, then only P0420. If the cam is bad it will set a cam code, but the ECM will go in default mode and still run the engine. Bad gas mileage, yes, But will still run. Best way to check a cat is remove the O2 sensor closest to the engine or loosen the exhaust flange. If it runs better, the cat is clogged up. Have the codes checked..
problems associated with the cam sensor are ---insecure sensor/rotor---air gap---wiring---and the sensor itself. In the workshop manual it will explain how to check the rotor security and the air gap. If all is ok use the code reader to reset the CPU an eliminate the code.
I cant explain the windows but the stalling can be the wiring harness at the under the hood . you did not mention engine size but i know on in line 6 the harness goes around the rear of valve cover if you move it around it will stall if bad.
the machine wont tell you that the sensor is bad... it tells you its getting a bad reading from the sensor. which means it could a problem in the wiring from the cam sensor to the pcm, the pcm itself, or the syncro that the cam sensor sits on if there is one in the vehicle your working on. could be a problem with the cam itself also but very rare
I don't know what your vehicle is, but the cam sensor monitors the camshaft position. and compares it to the crankshaft position. when they are not in sync it will throw a code. I would be looking at the timing belt/ chain. look for tensoiners or guides that have let go or that are loose, breaking down. Let me know
This is common, i've run into this problem, the aftermarket sensors are not right you will need a dealer sensor and theres an update reprograming that needs to be done so the crank and cam sensors algin and the light wont come back. hope this helps, you can try taking it to the dealer and see if they can reprogram with that sensor but it needs the updated program, there ar tsb bulltins on this is you reseach this it will explain it, also another problem depending on the engine you have is the cam gear spins a little making the reading off.
Possible but not likely. Usually a CAM sensor is uniformly bad on all cylinders when it is bad. I would suspect injectors or spark plug wires more. But the cam sensor is under the timing belt cover, in front.
when you unplug the cam sensor it runs?what that mean is that most likely your sensor is bad..reason for that is when your cam sensor is out you unplug it...it will run because it forces the computer to get a reading/signal from the crankshaft sensor or somewhere else like that..and when you plug it in it is getting a bad reading from the cam sensor wich will cause it not to run..so my advise is your cam sensor is bad..
