1990 Pontiac Bonneville mileage: 114,000. I have an error code 41 (camshaft sensor) that we cannot find the cause of. Only 4 volts are present on one side of the cam sensor (8 on the other side) The wiring is good between the Ignition Module and the Camshaft Sensor. We have replaced the ECM, Ignition Module, Coil Pack, Crankshaft Sensor, and Cam Sensor. Same symptoms. Correct Voltage at Computer. Bad voltage (4 volts on one side of sensor with it unplugged). Interestingly, when you pull the connection to the Crankshaft Sensor, then you have the correct voltage to the Cam Sensor (8 volts on both sides to Ground (middle wire to Cam Sensor). However, replacing the Crank Sensor does not solve problem. Any suggestions?

Your problem is one that generally takes days to identify and repair. Moreover, from here, it is really difficult to diagnosis your problem, but here is a suggestion of something you might try. Unplug the wiring loom from the PCM and check the resistance of all the ground wires in that wiring loom. You may have a bad ground causing your problem.
