P0344 -replaced both sensors and resets code right away

Question

1999 Oldsmobile 88 3.8L. I have replaced both sensors cam and crank sensors and resets code in about a quarter of a mile

Answer 1

Hi there,

When the code resets that fast either it indicates the timing is actually off or the wiring to the cam sensor is bad. If you test the wiring and it's good, then the issue would be the PCM.
