Walker Products 211-91002 Engine Coolant Temperature Sensor (ECT Sensor)

An engine coolant temperature sensor measures coolant temperature. It does this through changing resistance and sends this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered. Symptoms of failure include no start, engine flooding, steady check engine light and/or poor fuel economy. Recommended service should be performed every 25,000 to 35,000 miles and consists of cleaning or replacing sensors that are non-functional.
