How Does A Coolant Sensor Work At Lindy Green Blog An engine coolant temperature sensor or ect measures the temperature of the liquid coolant. a typical engine cooling temperature sensor is a negative temperature coefficient (ntc) thermistor, which means its electrical resistance decreases when the temperature increases. the tip of the ect sensor protrudes into one of the cooling system. Here is a more detailed list of the signs of a bad or failing coolant temperature sensor to look for: 1. check engine light. one of the first signs of all coolant temperature sensor symptoms you will probably notice is that the check engine light will show up on your dashboard. if the computer detects any problem with the sensor’s circuit, it.

How Does A Coolant Sensor Work At Lindy Green Blog A faulty engine coolant temperature sensor affects the way the pcm supplies fuel to the engine, which can reduce the vehicle’s engine performance. here are the most common symptoms that you might notice when your vehicle has a bad ect sensor. a faulty engine coolant temperature sensor affects the way the pcm supplies fuel to the engine, which. Reconnect the electrical connector. if you choose, you may use a small amount of di electric grease on the connector terminals to help keep water off of the pins, which would otherwise result in electrical resistance. add coolant. s tart the engine and check for coolant leaks around the sensor. A bad coolant temperature sensor may result in a lean fuel air mixture, causing a difficult cold start. 5. fluctuating temperature gauge. the engine temperature gauge on your car’s dashboard gets its input from the coolant temperature sensor. a faulty sensor can cause it to fluctuate erratically as you drive. 6. The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. this can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping. 4. check engine light comes on. an illuminated check engine light is another symptom of a potential.
