DTC P0118-00; ECT Sensor No. 1 Circuit High Input: Notes
DTC P0118:00 (SKYACTIV-G 2.0) DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0118:00 |
ECT sensor No. 1 circuit high input |
| DETECTION CONDITION |
- The PCM monitors the ECT sensor No. 1 signal. If the PCM detects that the ECT sensor No. 1 voltage at the PCM terminal 1AK is above 4.9 V for 5 s, the PCM determines that the ECT sensor No. 1 circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (engine cooling system).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA/Snapshot data is available.
- DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Fixes the water temperature for the engine control at 40 °C {104 °F}, and for the idle air control at 80 °C {176 °F}.
- Operates the cooling fan (high speed rotation).
- Inhibits the fuel cut control during shift change.
|
| POSSIBLE CAUSE |
- ECT sensor No. 1 connector or terminals malfunction
- ECT sensor No. 1 malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between ECT sensor No. 1 terminal A and PCM terminal 1AK
- Open circuit in wiring harness between the following terminals:
- ECT sensor No. 1 terminal A-PCM terminal 1AK
- ECT sensor No. 1 terminal B-PCM terminal 1AM
- PCM malfunction
