What should the coolant sensor resistance be in a cold engine?
In cold engine and an ambient temperature of 20 ºC the sensor resistance is between 2000Ω and 3000Ω. After the engine start, coolant temperature begins to rise. ECT gradually heats and its resistance reduces proportionately.
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 to do when your coolant sensor is replaced?
Properly dispose of used coolant. Step 16: Lower vehicle from jack stands. Place the vehicle back level to the ground. Once the coolant temperature sensor has been replaced, you need to start the engine, check for leaks, and refill the radiator fluid in most cases before you test drive the vehicle.
Where is the coolant temperature sensor located on a car?
The first item that needs to be completed after you compiled all of your tools and assets is to locate the coolant temperature sensor. In the image above, you can see that most coolant temperature sensors are located on the top, driver side of the engine. However, the location of this sensor may be different with your specific engine.
In cold engine and an ambient temperature of 20 ºC the sensor resistance is between 2000Ω and 3000Ω. After the engine start, coolant temperature begins to rise. ECT gradually heats and its resistance reduces proportionately.

Where is the intake air temperature sensor located?
You’ll see it on mounted on the engine block. It can be cleaned using a wire brush when you entirely change your engine coolant (approx. every 80,000 km or 50,000 miles). The intake air temperature sensor (IAT) tells the ECM the temperature of the air that is going into the engine.
Why is the temperature sensor on my car not working?
One of the common problems is when the sensor has poor connection inside or in the connector or in the wiring harness. This causes interruptions in the signal to the PCM and the PCM sets the fault. In some cars, symptoms of this problem show up as erratic readings of the temperature gauge.
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.
What does the coolant temperature sensor ( ECT ) do?
The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature. The onboard computer uses the signal of ECT as the main correction factor when calculating the ignition advance and the injection duration.
