DTC DETECTION LOGIC
| DTC No. | Trouble diagnosis (Trouble diagnosis content) | DTC detecting condition | Possible cause | |
|---|---|---|---|---|
| P0196 | EOT SENSOR [Engine oil temperature (EOT) sensor range/performance |
A) | Rationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signals from engine coolant temperature sensor and intake air temperature sensor. |
|
| B) | The comparison result of signals transmitted to ECM from each temperature sensor (ECT sensor, EOT sensor, and FTT sensor) shows that the voltage signal of the EOT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |
