Where is the Coolant Temperature Sensor Located?ĭifferent car manufacturers and brands have distinct ways of installing the coolant temperature sensor. However, if your vehicle only has a single coolant temperature sensor and it becomes faulty, your electrical fans may not function at all. Most automobiles come with two different temperature sensors for the fans, engine management and dashboard gauge. Some vehicles’ coolant temperature sensors control the electric cooling fans. This is a pointer that something is wrong with your coolant temperature sensor and must be checked out by a certified professional. This causes the engine to shake or vibrate when the vehicle is at low speed and can even bring about strange behaviors, power losses, etc.Įngines are highly sensitive, especially to inappropriate air-fuel mixtures at idle. Poor IdlingĪ faulty sensor can cause the fuel mixture to adjust.
This can be so severe that driving the vehicle in such a condition may result in environmental or excessive air pollution. This leads to the burning up of your vehicle’s exhaust pipe, thereby causing black smoke. This can cause the fuel mixture to be vibrant such that during combustion, the fuel can’t be adequately consumed within the chamber. This action confuses the computer and stimulates it to enrich the fuel mixture unnecessarily. The coolant temperature sensor can fail and transmit cold signals to the computer. But if your vehicle’s exhaust starts emitting black smoke, the coolant temperature sensor could be the culprit.

Black Smoke Emitted from the Engineįew drivers hardly notice this crucial coolant temperature sensor symptom. And the light will not go off until a specialist readily addresses the issue. If the computer detects an unsavory development with the sensor’s circuit or signal, it may set off the ‘Check Engine’ light. If the ‘Check Engine’ light suddenly comes on, this could imply a hitch with the coolant temperature sensor. And this will ultimately hamper engine performance. This will cause the automobile to use up more fuel than is necessary, thereby reducing fuel economy. The computer mistakenly assumes the engine is cold, even when it is not. It is also common for a coolant temperature sensor to fail without warning and send permanently cold signals to the computer. And the response of the computer may unbalance the timing and fuel calculations. If the coolant temperature sensor malfunctions, it can transmit a false signal to the computer. Poor fuel economy is another symptom that indicates your coolant temperature sensor is malfunctioning. This causes the computer to erroneously counterbalance the signal, thereby causing the engine to misfire or overheat. At times, the coolant temperature switch may fail such that it starts transmitting hot signals permanently. If you notice that your engine overheats, the coolant temperature sensor could be the problem. Symptoms of a Bad Coolant Temperature Sensor Overheating Engine These symptoms should alert you of potential problems with your automobile and push you to have it checked out thoroughly. This post discusses some of the common symptoms of a bad coolant temperature sensor. And this implies that if the coolant temperature sensor malfunctions, it may translate very quickly to engine performance hiccups. This occurs to prevent overheating, which can damage the engine severely.Īs you can see, temperature plays such a crucial role in the performance calculations of your engine. If the computer detects that the engine’s temperature is too high, it will automatically scale back engine performance settings. Most automobile engines require more fuel when they are cold but require less when fully warmed up. This includes changing the engine’s timing as well as the fuel calculations for premium performance. The signal generated is automatically transmitted to the computer so that necessary changes can be made. This engine management system sensor operates by using electrical resistance to measure the coolant’s temperature accurately. The coolant temperature switch – otherwise known as the coolant temperature sensor – is primarily responsible for monitoring the engine coolant’s temperature. A coolant temperature sensor remains one of the most vital engine management sensors.
