P0195: Engine Oil Temperature Sensor Malfunction
Can you still drive? Yes, but monitor your oil temperature gauge if available. If the engine overheats or oil pressure drops, stop immediately.
What Does P0195 Mean?
Code P0195 indicates a general malfunction with the engine oil temperature sensor circuit. The ECM uses oil temperature data to manage engine cooling, oil pressure, and variable valve timing systems. When the sensor signal is irrational or outside its expected range, this code is set.
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.
