What does coolant sensor do?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
What are the symptoms of a bad coolant sensor?
Common symptoms of a bad engine coolant sensors are overheating, hard starting conditions, poor idle, check engine light ON and the electric fans do not work properly. The easiest way is to read the trouble code memory and check the value from the sensor, to make sure it’s a possible value.
What does a bad coolant sensor do?
A failing coolant temperature sensor will prevent a vehicle’s engine from entering a closed loop. This will cause the vehicle to run rich meaning the engine’s fuel mixture will have a higher percentage of fuel to air which will result in diminished fuel economy.
What is the correct way to check a coolant temperature sensor?
If your vehicle won’t start when cold, the easiest way to check the engine coolant temperature sensor is to depress the gas pedal while cranking the engine. If it starts, that’s a pretty good sign the sensor is off.
Where do I find the coolant temperature sensor?
