Crankshaft Position Sensor: Testing and Inspection

In the electronic engine control system used on this vehicle, signals generated by the crank angle sensor are used by the ECU in its calculations for various outputs. When problems with these signals are detected, malfunction codes are set and can be retrieved from the on-board diagnostic system.

A faulty IGF signal will set malfunction code No. 01 in the on-board diagnostic system. A faulty "Ne" signal will set malfunction code 02. A problem with the "G" signal will set malfunction code 03.
