An engine temperature sensor, or coolant temperature sensor, is an digital system that measures the temperature of an engine’s coolant. This data is then despatched to the engine’s pc, which makes use of it to regulate the engine’s efficiency. A defective engine temperature sensor can result in quite a lot of issues, together with engine overheating or injury, in addition to decreased gasoline effectivity. Testing an engine temperature sensor is a comparatively easy process that may be carried out at house with a couple of fundamental instruments.
