DTC Detection Logic
NOTE:
If DTC P0196 is displayed with P0197 or P0198, first perform the trouble diagnosis for DTC P0197, P0198. Refer to
"DTC LOGIC ".
| DTC No. | Trouble diagnosis name (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 (IAT sensor, ECT sensor, FTT sensor, and EOT sensor) shows that the signal voltage of the EOT sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state. |
