| DTC P0117:00 |
ECT sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor signal. If the PCM detects that the ECT sensor voltage is below 0.2 V
for 5 s
, the PCM determines that the ECT sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (engine cooling system).
- The MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- Engine overheating (cooling system malfunction)
- ECT sensor connector or terminal malfunction
- ECT sensor malfunction
- Short to ground in wiring harness between ECT sensor terminal A and PCM terminal 2AH
- PCM connector or terminal malfunction
- Short circuit in ECT sensor signal circuit and ground circuit each other
- PCM malfunction
