Engine oil is needed to lubricate the inner workings of your engine and prevent damage from friction. It works alongside the coolant that circulates in and around the engine to cool it. However, engine oil temperature must be strictly controlled. If the temperature crosses a threshold, engine damage can result. The oil temperature sensor's job is to monitor oil temp and communicate the information with the car's computer. The oil temp is displayed in the dash in some models, but many newer models only display engine coolant temperature. The oil temperature sensor works in tandem with the water temperature sensor and other temperature monitors to ensure that the temperature remains within an acceptable range. Like all other sensors, the OTS is subject to high heat on a regular basis, which can damage the wiring harness. If the oil temperature sensor fails, the oil temperature will read incorrectly or not at all. Monitoring the temperature of your engine during operation is essential. If the temperature rises to a critical level, the oil will damage the engine. With a functional oil temperature sensor, you will be able to monitor operating conditions and turn off the engine if necessary. Have the sensor inspected by our expert mechanics if you suspect that it is malfunctioning. Without access to accurate information about the oil temperature in your engine, the situation can become critical. If you believe there is a problem with the oil temperature sensor in your car, have the problem diagnosed by our experienced mechanics immediately.
