A bad coolant temperature sensor can cause your car to stall, according to The Truth About Cars. This is because the car relies on the sensor to tell it when the coolant is too hot, and when it gets too cold, the car will stop working. If you have a low coolant temperature sensor, this could be causing your car to stall. While there are many things that can go wrong with your car, a bad coolant temperature sensor is one of the most common causes of a stalled car. If you experience a stall while driving and think that your coolant temperature sensor may be the problem, take your car into a mechanic and have them check it out for you.
What is a Coolant Temperature Sensor?
A coolant temperature sensor is a device that monitors the coolant temperature in a car. If the coolant temperature becomes too high, the sensor can cause the car to stall.
How Do Coolant Temperature Sensors Work?
The car’s cooling system works by circulating coolant through the engine and then back to the radiator. The radiator stores heat until it can be expelled out of the car.
Coolant temperature sensors work by sensing when the coolant is too hot or too cold. When the sensor detects that the coolant is too cold, it will turn on the car’s AC to help warm up the coolant. When the sensor detects that the coolant is too hot, it will turn off the AC to prevent damage from happening to the car’s engine.
What to Do If Your Car Stalls Because of a Bad Coolant Temperature Sensor
If you’re driving your car and it stalls, one of the first things you should do is check your coolant temperature sensor. A bad coolant temperature sensor can cause your car to stall, and if you don’t catch it in time, it could lead to a more serious problem down the road.
Here are four ways to check if your coolant temperature sensor is causing your car to stall:
First, turn off your car and disconnect the battery. Next, use a thermometer to measure the interior temperature of your engine bay. If the temperature is above normal, then the sensor may be causing your car to stall. If you can’t determine which part of the engine bay is causing the high temperature, then you can also test the sensor by connecting a wire from the sensor to a metal object and measuring how long it takes for the voltage to drop below 3 volts. If there’s an issue with the sensor, then replacing it will solve the problem.
If none of these tests work, then there may be something else going on with your car that’s causing it to stall. However, testing and replacing the coolant temperature sensor is always a good idea in case it’s causing the stall.
Conclusion
If your car has a bad coolant temperature sensor, it could cause the car to stall. If you’re experiencing any of these symptoms, it’s important to bring your car in for service: -The engine will not start. -Car struggles to accelerate. -The check engine light is on.
