DTC P0117: Notes
DTC P0117 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0117 |
ECT circuit low input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor signal at PCM terminal 2AQ. If the PCM detects ECT sensor voltage of 0.18 V or below
, 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
- Short to ground circuit between ECT sensor terminal A and PCM terminal 2AQ
- Short each harness ECT sensor terminal A and B
- PCM malfunction
