CID 0320 FMI 02 Speed/Timing Sensor Loss of Signal

Usage:

3126B 3GS
Conditions Which Generate This Code:

The signal for the primary engine speed/timing sensor is intermittent or lost.

System Response:

The Electronic Control Module (ECM) will log the diagnostic code.

  • Engine shutdown

Note: The engine will shut down only if both the primary engine speed/timing sensor and the secondary engine speed/timing sensor fail.

Test Step 1. Perform the following diagnostic procedure: Engine Speed/Timing Sensor Circuit - Test

Results:

  • OK - STOP
