DTC P0117 (L3) DETECTION CONDITION & POSSIBLE CAUSES
| DTC P0117 |
ECT sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor signal at PCM terminal 2AH. If the PCM detects the ECT sensor voltage below 0.2 V for 5 s
, the PCM determines that the ECT sensor circuit has 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.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- ECT sensor connect or terminal malfunction
- ECT sensor malfunction
- Short to ground in wiring harness between ECT sensor terminal A and PCM connector terminal 2AH
