Cold oil is thick and resistant to flow, while hot oil becomes thinner and less effective at lubricating. Understanding its function is the first step in appreciating its importance.
This allows for the detection of intermittent faults that might not trigger a permanent check engine light. How the Oil Temperature Sensor Works At its core, the sensor operates using a thermistor, a type of resistor whose resistance changes with temperature.
