Code 14, Coolant Temp Sensor Signal Volt Low: Notes
NOTE:
Test numbers refer to test numbers on diagnostic chart.
- Checks to see if code was set as a result of a hard failure or an intermittent condition. Code 14 will set if engine has been running for more than 10 seconds and signal voltage indicates a coolant temperature more than 275°F (135°C) for more than 3 seconds.
- This test simulates conditions for a Code 15. If the ECM recognizes the open circuit by displaying a low temperature, ECM and wiring are not at fault.
