DTC P0118:00: Notes

DTC P0118:00	ECT sensor circuit high input
DETECTION CONDITION	The PCM monitors the ECT sensor signal. If the PCM detects that the ECT sensor voltage is above 4.6 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	ECT sensor connector or terminal malfunction ECT sensor malfunction PCM connector or terminal malfunction Short to power supply in wiring harness between ECT sensor terminal A and PCM terminal 2AH Open circuit in wiring harness between ECT sensor terminal A and PCM terminal 2AH Open circuit in wiring harness between ECT sensor terminal B and PCM terminal 2AY PCM malfunction
