CID 0342 FMI 03 Secondary Engine Speed open/short to +batt
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the following conditions:
- Engine speed is zero rpm.
- Engine speed input is high for at least two seconds.
System Response:
The ECM will log the diagnostic code.
- Engine misfires
- 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
