A coolant temperature sensor is responsible for monitoring the temperature of the engine coolant and relaying that information to the car’s computer. The computer then uses that information to adjust the fuel mixture and ignition timing. A failing coolant temperature sensor can cause overheating, as the computer will not be able to adjust the engine’s settings properly.
When it comes to how long a coolant temperature sensor lasts, there are a lot of variables. In this article, we will talk about how long a coolant temperature sensor usually lasts.
How Long Does A Coolant Temperature Sensor Last
It’s normal for engine coolant temperature sensors to damage. The sensor may corrode at the point where it enters the engine coolant channels if you don’t maintain the engine cooling system as directed by the manufacturer’s guidelines. Most coolant temperature sensors will last the lifetime of the vehicle, but they can fail prematurely. Usually, after 100,000 miles, the engine coolant temperature sensor needs to be replaced. The sensor could fail significantly sooner if the engine cooling system is not properly maintained.
In that case, a service professional will use a diagnostic scan tool to identify the issue once the check engine light illuminates. The on-board diagnostics port, located under the dashboard of the vehicle, is where the user will connect the scan tool. The codes generated by the data stored in your car’s computer will be compared to the settings. The coolant temperature sensor will be examined by your mechanic if the temperature readings are inaccurate. If that is the issue, the sensor and sensor circuit will be examined to see if replacement is necessary or not.
Your automobile specialist will unplug the electrical connector from the sensor in order to replace it. Before a new sensor is installed into the thermostat housing or engine block, a sealant will be sprayed on its threads.
In general, sensors have high durability. They might even outlive your car if there are no electrical or other problems. The coolant temperature sensor can, however, stop working due to wear and use. If the sensor fails, your car’s temperature control cannot work properly. This may result in a number of problems, including overheating and strange engine behavior. The coolant temperature sensor does not generally have a recommended replacement period.
