Description






DESCRIPTION

The crankshaft position sensor mounts to the rear of the engine block near the transmission.





The PCM uses the Crankshaft Position sensor to calculate the following:

- Engine RPM
- TDC number 1 and 4
- Ignition coil synchronization
- Injector synchronization
- Camshaft-to-crankshaft misalignment (Timing belt skipped 1 tooth or more diagnostic trouble code).
