While the coolant temperature might be cooler than the ambient air, the coolant temperature can send inaccurate readings to the car computer. Especially if the engine doesn’t warm as it supposes to, you have to contact your mechanic to diagnose and track down the problem in your cooling system. If you notice temperature fluctuations in your temperature gauge, or it stays lower or higher than expected when the engine is running, it could be an indicator of a failing or lousy coolant temp sensor. So, before a coolant temp sensor failure escalates to more significant auto repair for your transmission or engine, it will give the following signs Irregular temperature readings:

In this article, we’ll discuss at length how to tell if your coolant temp sensor is bad, the signs and symptoms of a defective coolant temp sensor, and how to fix the problem. Hence, you should always watch out for symptoms of a bad coolant temp sensor.

The sensor sends a signal to the car computer to make changes for gas calculation and engine timing for peak performance.Īs the vehicle engine requires less gas when warmed and more gas when cold, the car computer will adjust the engine performance setting if it receives a signal that coolant temp is above the normal operating temperature to save the engine from catastrophic damages due to the engine overheating.īecause the coolant temperature sensor plays a critical role in the engine timing and calculation for optimal performance, a lousy coolant temp sensor can easily affect your engine’s performance.

The coolant temp sensor functions perfectly by monitoring the coolant temp with the aid of an electrical circuit. The coolant temp sensor is one of the car engine management systems that monitor the temp of the radiator coolant.
