The coolant temperature sensor is a crucial part of your car’s cooling system. It helps regulate the engine temperature by constantly sending information to the car’s computer while it is running. If this sensor is malfunctioning, it can cause the engine to overheat and consume more fuel. That’s why you should entrust it only to engine coolant temperature sensor experts in Phoenix, AZ.

As such, our seasoned experts at Virginia Automotive share three things you must know about coolant temperature sensors. Here they are:

1. How does your vehicle’s coolant temperature sensor work?

The coolant temperature sensor is a small, cylindrical component located near the radiator. Moreover, it is directly connected to the Engine Control Module (ECM) of most modern vehicles.

As its name suggests, it monitors coolant temperature and sends that information to the car’s computer. The computer then uses this information to determine how much cooling is needed and adjusts the engine’s performance accordingly.

For example, this device instructs the engine to adjust the fuel mix, fuel injection, ignition timing, and cooling fan. The data from the coolant temperature sensor is also displayed on the engine temperature gauge on your dashboard.

2. What are the symptoms of a faulty coolant temperature sensor?

There are three main symptoms of a faulty coolant temperature sensor. First, the Check Engine Light will come on. This indicator may mean dozens of other car problems, so it’s best to bring your car to experienced mechanics for diagnostics. Our team in Phoenix, AZ, will accurately determine whether your coolant temperature sensor is the root cause behind this.

Secondly, your vehicle will likely overheat. If the engine temperature gauge is constantly in the red, this is a clear sign that the coolant temperature sensor is not working properly.

Lastly, the performance of your car may decrease. You might experience poor acceleration, or the engine might stall frequently. Additionally, you may have noticeable drops in fuel efficiency.

3. How to repair a faulty coolant temperature sensor in Phoenix, AZ?
