ECT SEN/CIRC (Engine coolant temperature sensor 1 circuit range/performance) |
A |
Diagnosis condition |
Engine cold start |
|
Signal (terminal) |
Engine coolant temperature sensor signal |
|||
|
Threshold |
The comparison result of signals transmitted to ECM from each temperature sensor (IAT 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 |

Signal (terminal) |
Engine coolant temperature sensor signal |
