Changing Codes every time i clear them.???

[darringraviet]

had camshaft sensor codes come up constantly and replaced it 3 or 4 times with part from autozone. usually all the code problems would go away with replacement for 6 months. But this time...... codes keep popping up and none of them are camshaft sensor related.

It is hard to replace a part if the computer keeps telling me different stuff is messed up. What do you think could be the culprit of this? truck runs fine if the computer would let it!!!

I'm having the same issues with my dads '02. We just ordered a new PCM. I printed out all the wiring diagrams and checked all my PWR and GRNDs and got nothing. I'll let you know how it goes.

On some trucks the Crank Shaft Sensor has to be replaced at the same time the Cam Shaft Sensor is replaced.
