I have a 91 regal 3.8 giving me a code 41. The code is persistant and appeared after a short full throttle condition. I understand this a camshaft sensor problem, but can anyone tell me what the voltages and test procedures should be? After searching the other threads I understand it may be the magnet on the camshaft as well, which I'm afraid is going to be the case. I just want to test the sensor before replacing it. I have a digital VOM meter and an O-scope if needed. Any help would be appreciated.
