|---|---|---|---|
| P0116 | ECT SEN/CIRC [Engine coolant temperature (ECT) sensor circuit range/performance] |
The comparison result of signals transmitted to ECM from each temperature sensor (ECT sensor, FTT sensor, and EOT sensor) shows that the voltage signal of the ECT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |
