Where is the temperature sensor on a 2008?
Coolant temperature sensor is located on the radiator next to the front of the engine.
What are the symptoms of a bad coolant temperature sensor?
Symptoms of a Bad Coolant Temperature Sensor If your vehicle starts to use a lot more gasoline than usual, or black smoke is starting to come from the exhaust pipe, these are indicators that the coolant temperature sensor in your vehicle could be defective, and needs to be replaced.
What does coolant temperature 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 should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
How does the cylinder head temperature sensor work?
Some cars use a cylinder head temperature or CHT sensor instead of, or in addition to the ECT sensor. The CHT sensor (see the photo) works the same way, but it measures the temperature of the cylinder head metal and is not immersed in coolant. This allows the CHT sensor to measure the temperature of the engine correctly even with loss of coolant.
Where is the temperature sensor on a car?
This will vary on some cars where the pulleys are located on the side of the vehicle. However, the sensor is still located amongst the pulley system. Hold a drop light over the area and locate the sensor. You may need to remove the fan shroud in order to see into the space.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.

What do I need to test my coolant temperature sensor?
All you are going to need is thermometer and voltmeter to test the temperature sensor. The coolant temperature sensor will show different om reading at different temperatures. We will include the graph in the video so you can use it to test your temperature sensor.
What happens if the coolant sensor is not working?
When the coolant temperature sensor is not working properly the car will run sluggishly and could overheat. Replacing this sensor is an easy project that can be done in your own garage or on a flat driveway. On a newer car, locate the hood release beneath the steering wheel inside the car.
Where is the temperature sensor on a fan?
Hold a drop light over the area and locate the sensor. You may need to remove the fan shroud in order to see into the space. The sensor will have a terminal exposed with a single wire coming from it. The sensor sends its signals along a lone lead wire that is located at the top of the terminal.
