P0336 and P0341

[MENEGENE]

I'm working on a 96 Cutlass Supreme 3100 that keeps setting P0336 24x Reference Signal Circuit and P0341 CMP Sensor Circuit Performance faults. I was wondering if anybody has ever seen this before and what could be causing it. I was thinking there may be a problem in the ignition secondary causing interference. Just thought I'd check here for other ideas. This vehicle has about 190,000 miles on it.

RE: P0336 and P0341

I've heard of crank sensors (the 24x one) failing before. Or it could be an issue with the reluctor wheel. I'd look at the reluctor wheel first since its free, and then possible try to look more into the 24x crank sensor.
