Car Engine Temperature Sensor

The engine temperature sensor informs the engine s ecu about the current ongoing variations in the engine temperature.

Car engine temperature sensor. An engine temperature sensor also known as engine coolant temperature sensor ects or coolant temperature sensor cts is a small device in your engine s cooling system. The exhaust temperature sensor is often installed in diesel engines. It is used to measure the exhaust gas temperature before and after the particle filter in order to optimize particle filter regeneration. On most vehicles the coolant temperature sensor cts can be found somewhere near the engine thermostat which allows it to function optimally.

There are many ways you can tell if your engine s temps are shooting up. The tip of the cts is probably located right next to the engine coolant. The coolant temperature sensor abbreviated as cts in your car is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason. It is found along the coolant pipe and works with your vehicle s electronic control unit ecu.

Depending on the vehicle engine model you often have 1 to 4 exhaust gas temperature sensors. The coolant temperature sensor s function. Ecu in turn adjusts and regulates the fuel quantity ignition timing. The sensor works by measuring the temperature that s being given off by the thermostat and or the coolant itself.
