Its viscosity, or thickness, is highly dependent on temperature. If the sensor provides a false cold reading, the engine might run too rich or retard timing, wasting fuel.
Symptoms of a Bad Oil Temp Sensor and Engine Performance Issues
How the Oil Temperature Sensor Works At its core, the sensor operates using a thermistor, a type of resistor whose resistance changes with temperature. The oil temp sensor ensures the engine operates within the ideal viscosity range.
Advanced diagnostic tools can graph the sensor's output, showing the temperature curve during a cold start, warm-up, and normal operation. It is typically threaded directly into the engine block or the oil pan, positioned where it can make direct contact with the oil flowing through the galleries.
Symptoms of a Bad Oil Temp Sensor Affecting Engine Performance
On some performance vehicles, a second sensor might be located in the oil cooler line. Impact on Engine Performance and Longevity Engine oil serves multiple roles, including lubrication, cooling, and cleaning.
