HELP! cam sensor error... and its NOT the cam sensor
'94 Bonniville with 3800 (I hope this is the right forum to post in.)
MIL is on, scanner says "camshaft sensor circuit malfunction".
I have replaced cam sensor, seemed an easy thing.
Magnet is in place, and is reasonably strong.
Wires ohm good from sensor to ICM.
Will NOT run with crank sensor disconected.
Is a disparity where Tach reads about 1100rpm and scanner shows about 825rpm.
I'm guessing crank sensor issue. Any way to test this?
I'd had for it to be the ECU.
Thanks for any help or suggestions!
