An engine coolant sensor is a tool that measures the temperature of the coolant in an inner combustion engine. It’s sometimes positioned within the cylinder head or radiator hose and gives enter to the engine’s digital management unit (ECU) to regulate the gasoline combination and ignition timing. A defective engine coolant sensor can result in a lot of issues, together with engine overheating, poor gasoline financial system, and decreased efficiency.
Testing an engine coolant sensor is a comparatively easy process that may be carried out at dwelling with just a few primary instruments. First, disconnect {the electrical} connector from the sensor. Subsequent, use a multimeter to measure the resistance between the sensor’s terminals. The resistance ought to be inside the producer’s specs. If the resistance is simply too excessive or too low, the sensor is defective and ought to be changed.
