DTC P0195-11: Engine Oil Temperature Sensor Circuit Short to Ground [12/2021 - ]: Description
A thermistor, whose resistance changes in accordance with the engine oil temperature, is built into the engine oil temperature sensor. As the engine oil temperature decreases, the thermistor resistance increases and as the engine oil temperature increases, the thermistor resistance decreases. The engine oil temperature sensor is connected to the ECM. A voltage of 5 V is supplied from terminal THEO via resistor R of the ECM. Since resistor R and the engine oil temperature sensor are connected in series, both the resistance and the electrical potential of THEO are subject to change in accordance with a change in the engine oil temperature.

HINT:
When a DTC is output, check the Data List item "Engine Oil Temperature Sensor" using the GTS.
Refer to DATA LIST / ACTIVE TEST [12/2021 - ]
| DTC No. | Engine Oil Temperature Sensor | Malfunction |
|---|---|---|
| P0195-11 | Higher than 164°C (327°F) | Short to ground in THEO circuit |
If the Data List displays a normal value, the normal value may be due to a temporary recovery from the malfunction condition. Check for intermittent problems.
