Where is the temperature sensor located?
Usually, this sensor is located behind the grille but is in front of the radiator and radiator support. This is the best location for the sensor as it is away from the heat of the engine and can accurately read the ambient temperature of the air around it; that is the temperature of the air entering the intake manifold at the front of the engine.
What are the symptoms of a bad coolant temperature sensor?
Another symptom of a problem with the coolant temperature sensor is an overheating engine. 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.
What happens if the coolant sensor is not working?
Without a properly operating cooling system, the engine will run hot which will cause the engine to operate inefficiently and may result in serious damage. The coolant sensor is basically a thermometer that reports the internal engine temperature to the engine’s control computer.
