| DTC P0116:00 |
ECT sensor circuit range/performance problem |
| DETECTION CONDITION |
- The PCM monitors the maximum value and minimum value of engine coolant temperature when the engine is started and 5 min have been passed after leaving the vehicle 6 h or more. If difference between maximum and minimum values of engine coolant temperature is below 6°C {11°F} the PCM determines that there is an ECT sensor circuit range/performance problem.
Diagnostic support note
- This is a continuous monitor (engine cooling system).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
