P0196: Engine Oil Temperature Sensor Range/Performance
Can you still drive? Yes, this is a low-severity code. The oil temperature reading is used for oil life monitoring and minor calibration adjustments. Driving is safe, but the oil life monitor may not be accurate.
What Does P0196 Mean?
Code P0196 indicates that the engine oil temperature sensor is reading outside of the expected range for the current engine operating conditions. The ECM compares the oil temperature to the coolant temperature and ambient temperature during warm-up, and flags P0196 when the oil temperature reading does not correlate logically with other temperature inputs.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

Frequently Asked Questions
Where is the engine oil temperature sensor?
The oil temperature sensor is typically located in or near the oil filter housing, the oil pan, or the engine block near an oil gallery. Some vehicles integrate it into the oil level sensor in the oil pan.
Can overfilling oil cause P0196?
Indirectly, yes. Overfilling can cause oil aeration and abnormal temperatures, which may cause the sensor to read outside expected ranges. Always fill oil to the correct level on the dipstick.
