DTC P0117: Engine Coolant Temperature (ECT) Sensor 1 Circuit Low Input
WARNING: This page is about a different variant/trim than selected.
P0117 - ENGINE COOLANT TEMPERATURE (ECT) SENSOR 1 CIRCUIT LOW INPUT
| Description: | Indicates the sensor signal is less than the self-test minimum. The ECT sensor minimum is 0.2 volt or 121 °C (250 °F). Note: On some vehicles that are not equipped with an ECT sensor, a cylinder head temperature (CHT) sensor can be used and can set this DTC. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | An ECT V PID reading less than 0.2 volt with key on engine off (KOEO) or during any engine operating mode indicates a hard fault. | ||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
| Vehicles with only a cylinder head temperature (CHT) sensor | GO to DL: Cylinder Head Temperature (CHT) Sensor STEP DL7. | GO to DL: Cylinder Head Temperature (CHT) Sensor STEP DL7. | GO to DL: Cylinder Head Temperature (CHT) Sensor STEP DL14. |
| Vehicles with only an engine coolant temperature (ECT) sensor | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX11. | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX11. | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX15. |
| Vehicles with both a CHT and an ECT sensor | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX11. | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX11. | GO to DX: Engine Coolant Temperature (ECT) Sensor STEP DX15. |
