DTC P0117:00: Notes

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
