Oil temperature sensor

2015-12-31

When the car is on the go, almost every part that’s moving generates heat. If you’re not cautious enough to take note of these things, your car may break down in the middle of nowhere because of engine overheating or damaged components.

The oil temperature sensor monitors the temperature of the engine oil. This sensor’s purpose is to measure the oil temperature and display this measurement to the vehicle’s occupants. The engine can be in danger of damage if it operates at too high a temperature. As with the coolant temperature sensor, the OTS sensor allows operators to stop the vehicle and switch off the engine if the temperature of the oil gets too high as a result of an over heated engine. This would prevent any permanent damage to the engine.

The engine coolant temperature (ECT) sensor is a relatively simple sensor that monitors the internal temperature of the engine. Coolant inside the engine block and cylinder head(s) absorbs heat from the cylinders when the engine is running. The coolant sensor detects the change in temperature and signals the Powertrain Control Module (PCM) so it can tell if the engine is cold, warming up, at normal operating temperature or overheating.
