NOTE:
If DTC P0196 is displayed with P0197 or P0198, first perform the trouble diagnosis for DTC P0197 or P0198. Refer to DTC 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. |
