Engine Coolant Temperature Sensor Purpose Location And Failure Signs The engine coolant temperature sensor is responsible for monitoring the temperature of the engine coolant. it sends this information to the engine control module, which uses it to adjust the fuel injection and ignition timing. this helps ensure that the engine runs smoothly and efficiently, and that the emissions are kept within acceptable. The most common symptoms of a bad coolant temperature sensor include poor mileage, cooling fans not coming on, engine performance issues, an overheating engine, and a check engine light on your dashboard. here is a more detailed list of the signs of a bad or failing coolant temperature sensor to look for: 1. check engine light.
Coolant Temperature Sensor Location Where Is My Coolant A faulty engine coolant temperature sensor affects the way the pcm supplies fuel to the engine, which can reduce the vehicle’s engine performance. poor mileage if the ect sensor sends the wrong signal to the pcm (the engine is hot or cold when it’s not), the computer can produce an incorrect air fuel mixture and cause the engine to consume. Coolant is leaking under the motor: it's also common for the coolant temperature sensor to become loose and cause engine coolant to leak from under the motor. if you notice coolant in front of the motor, it may be coming from the engine coolant temperature sensor's location. note: the process of removing the coolant temperature sensor is very. 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 passages and is immersed in coolant. many cars have more than one coolant temperature sensor. 1. your check engine light is on: if the engine’s computer detects a problem with the coolant temperature sensor, or its circuit, it will turn on the check engine light. 2. your engine stalls: when the engine is first started, it will require more fuel in order to idle smoothly until it’s warmed up. the signal from the coolant temperature.

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.
