CID 0110 FMI 04 Engine Coolant Temperature short to ground
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects the following conditions:
- The ECM reads signal voltage that is below 0.2 VDC for one second.
- The ECM has been powered for at least three seconds.
System Response:
The ECM will log the diagnostic code. The ECM flags coolant temperature as invalid data and a default value of −40 °C (−40 °F) is used.
- Engine misfires
- Low power
- Reduced engine speed (rpm)
Test Step 1. Perform the following diagnostic procedure: Engine Sensor Open/Short Circuit - Test
Results:
- OK - STOP
