The engine coolant temperature sensor must be changed approximately every 100,000 miles on average. Unless you keep your engine cooling system in good working order, the sensor may fail considerably sooner than expected. A service professional will use a diagnostic scan tool to establish the cause of the problem if this occurs, and the check engine light will illuminate.

What are the symptoms of a bad coolant temperature sensor?
Engine overheating, a check engine light on, poor fuel efficiency, a rough idle, and poor engine performance are all possible indicators of a defective coolant temperature sensor, among other things. Coolant Temperature Sensor: What is the operation of coolant temperature sensors?
What happens if you don’t replace your coolant temperature switch?
Without the CTS, your vehicle’s engine would perform badly and overheat on a frequent basis, causing it to overheat and fail to start. If the situation is not addressed, the engine will eventually fail and the car would become unusable. The Coolant Temperature Switch (Sensor) Replacement service is the most often requested service by readers of this site.
How does a coolant temperature sensor work?
A typical engine cooling temperature sensor is a Negative Temperature Coefficient (NTC) thermistor, which implies that as the temperature rises, the electrical resistance of the sensor falls. One of the cooling system tubes has the tip of the ECT sensor protruding into it, which is submerged in coolant at the time. Many automobiles are equipped with more than one coolant temperature sensor.
How long do temperature sensors last?
The air charge temperature sensor, like the majority of electrical components in your car, may be anticipated to live for around five years. Misfires are one of the indications that your vehicle’s air charge temperature sensor may need to be replaced.
Should I replace my coolant temp sensor?
Your engine is running hot and consuming more gasoline than usual. P011X codes indicate that it is time to replace the coolant temperature sensor in your vehicle.
What are the signs of a failing temperature sensor?
- The following are the most noticeable signs of a faulty coolant temperature sensor: The Check Engine Light is illuminated.
- Overheating of the engine
- Fuel economy is substandard.
- Engine Performance Is Subpar
- Pump for water not working properly
- The ability to control the cooling fan
- Exhaust pipe emitting a thick black smoke
What happens when the coolant temperature sensor goes out?
The coolant temperature sensor may malfunction, resulting in the transmission of cold signals to the computer.This action causes the computer to get confused, and it encourages it to enrich the fuel mixture needlessly as a result.As a result, the fuel mixture may become too lively, and the fuel may not be able to be utilized sufficiently within the combustion chamber during the combustion process.
Can a coolant temp sensor cause starting problems?
Cold starting difficulties are caused by a faulty coolant temperature sensor. The owner, on the other hand, had to keep the engine going by pumping the pedal. If you have to constantly push the gas pedal to keep your car going in the morning, you may have a faulty engine coolant temperature sensor.
Does coolant temp sensor affect idle?
Is it possible for a faulty coolant temperature sensor to create choppy idle?Yes, as a result of the erroneous signal supplied to the auto computer, the air-fuel combination will be adjusted.The provided mixture will not be sufficient, resulting in vibrations and shaking at idle or during low-speed maneuvers, as well as other unusual behavior and a loss of engine power in other situations.
How much does it cost to replace a coolant temperature sensor?
A replacement engine temperature sensor will cost you between $150 and $193 on average, depending on the model. Labor expenses range between $82 and $105 per hour, while component prices range between $66 and $88 per hour. Taxes and fees are not included in the estimated cost of the project.
Does the coolant temp sensor control the fan?
As soon as the control system receives the temperature reading from the CTS, it may decide whether or not to switch on or turn off the cooling fan. Besides that, it may indicate the requirement for a richer fuel mixture or the necessity to open the exhaust gas recirculation system.
How do I know if my temperature sensor is working?
- How do you test a thermocouple or resistance thermometer that is not working properly?
- Check to see if the -ve and +ve leads have been switched.
- Check for any problems with the thermocouple cable wiring.
- Check for problems with the local heat source.
- Ensure that the Temperature Transmitter settings are correct.
- Check the settings on the temperature controller.
- The use of a multimeter for troubleshooting temperature sensors
