DTC P0118: Notes
DTC P0118 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0118 |
ECT circuit high input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor signal at PCM terminal 2AQ. If the PCM detects ECT sensor voltage of 4.58 V or above
, the PCM determines that the ECT sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (Engine cooling system).
- MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- ECT sensor malfunction
- Connector or terminal malfunction
- Open circuit between ECT sensor terminal A and PCM terminal 2AQ
- Short to power circuit between ECT sensor terminal A and PCM terminal 2AQ
- Open circuit between ECT sensor terminal B and PCM terminal 2AJ
- PCM malfunction
