MID 036 - CID 0110 - FMI 03 Engine Coolant Temperature open/short to +batt
Conditions Which Generate This Code:
The signal from the engine coolant temperature sensor to the Electronic Control Module (ECM) is greater than 4.8 VDC for at least five seconds.
System Response:
The ECM assumes the last valid value for engine coolant temperature. The monitoring of the coolant temperature is disabled. This disables the engine protection for low coolant temperature and high coolant temperature.
The fuel is shut off. The shutdown output is activated. The code is logged.
Possible Performance Effect:
Since the engine protection is disabled, the engine is shut down.
Troubleshooting:
This condition indicates the possibility of an open circuit or a short circuit.
Test Step 1. Perform the following diagnostic procedure: "Analog Sensor Signal"
Results:
- OK - STOP
