Looking at a car with an RPM sensor fault. Any info is appreciated on what it is and how it affects a car.

What is the specific numerical code? RPM data is fed to the PCM by the optical cam position sensor in the Optispark distributor. The is a code for the high resolution pulse signal (P0372) and another for the low resolution pulse signal (P1371). Also one for an intermittent low res signal (P0323).
Is the engine running? Will not run with active P1372, will run with P0371.Last edited by Injuneer; 12-30-2018 at 11:25 PM.
