![]() ![]() If you have a broken coolant sensor, it will automatically translate into bad performance of the vehicle when hot. Temperature plays a very important role when it comes to engine performance calculations. Symptoms of a Broken Coolant Temperature Sensor Imagine you run your car at high RPM alot and you are not aware that your sensor is bad, the car thinks the coolant temperature is normal and the fans don’t hook up when the vehicle goes above operating temperature and your engine will overheat, so address these issues with time. Overheating is a big issue for some engines, since they are prone to overheat, and these sensors are increasing the chance of overheating even more. The main computer also will scale downgrade engine performance settings, if this coolant temperature sensor detects that the temperature in the engine is too high in order to prevent the engine from possible damage caused by overheating. It does this because engines require less fuel when they are warm and more fuel when they are cool. Then this signal is sent to the ECU and the computer can make changes to the engine timing and also on the fuel calculations in order to get optimal performance. This computer then evaluates the signal and delivers constant adjustments to other components in the engine based on the new data.Ĭoolant temperature sensors are operating by using electrical resistance in order to measure the temperature of the coolant. Many sensors are regulating the work of the engine and send the data to the ECU that is the main computer on the car. And the coolant can also prevent freezing during the winter because the coolant is created for this specific purpose. The coolant runs through the engine to keep your car at operating temperature and prevent overheating. The coolant temperature sensor, also known as the coolant temperature switch, this sensor purpose is to monitor the temperature of the engine’s coolant. You probably don’t want to pay mechanics for these easy fixes. We are going to get in the details and explain how this sensor works and also get into the ways you can diagnose it and also fix it by yourself because if you are reading this. To find out what is causing these troubles. So, if you see a check engine light on your dash, better pay a visit to your local mechanic and they will make sure that your car is fixed and you should be back on the road in no time.īut we are here to learn more and dive deep into this issue. Usually, when a sensor breaks all kind of things can go wrong, bad idling, losing power, overheating, you name it. This sensor sends the engine incorrect information it may confuse the computer and make the car run badly. If your sensors go bad especially the coolant temperature sensor. Sensors are parts that are sending information to your main ECU and then the computer basing on this information is deciding what to do in this situation. Symptoms of a Broken Coolant Temperature SensorĬars are packed with technology these days, and sensors are known to go bad more often than other parts.If you see some of these symptoms happening you should probably consider checking out this sensor in order to get things done and make your car run properly. Some simple things may also cause this issue, simple as a coolant temperature sensor, which may be the culprit that you are looking for. ![]() Lately, you started gaining poor fuel economy, black smoke from the exhaust, overheating issue, and maybe even a check engine light? You probably think something really bad is happening with your car and you think of the worst, that it may die while you are driving, but you shouldn’t worry. So, you have noticed something weird is happening to your car. ![]()
