P0196 INFINITI – Engine Oil Temperature Sensor Range/Performance

P0196 INFINITI Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light)

P0196 INFINITI Possible Causes

Faulty Engine Oil Temperature sensor,Engine Oil Temperature sensor harness is open or shorted,Engine Oil Temperature sensor circuit poor electrical connection

P0196 INFINITI Description

The engine oil temperature sensor is used to detect the engine oil temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine oil temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
