DTC DETECTION CONDITION & POSSIBLE CAUSES
| DTC P0116:00 |
ECT sensor No.1 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 {43 °F}
the PCM determines that there is an ECT sensor No.1 circuit range/performance problem.
Diagnostic support note
- This is a continuous monitor (engine cooling system).
- The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
