An engine temperature sensor, or coolant temperature sensor, is an digital machine 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 a wide range of issues, together with engine overheating or injury, in addition to decreased gas effectivity. Testing an engine temperature sensor is a comparatively easy process that may be carried out at residence with a couple of primary instruments. First, find the sensor, which is usually positioned close to the engine’s thermostat. After getting positioned the sensor, disconnect {the electrical} connector and take away the sensor from the engine. Subsequent, join a multimeter to the sensor’s terminals. The multimeter ought to be set to the ohms setting. If the sensor is functioning correctly, the multimeter will show a studying of between 200 and 300 ohms. If the sensor shouldn’t be functioning correctly, the multimeter will show a studying of infinity. In case you are not sure take a look at an engine temperature sensor, you’ll be able to all the time seek the advice of a professional mechanic. Changing a defective engine temperature sensor is a comparatively cheap and simple restore that may assist to forestall severe engine injury.
