One of the most important of these sensors—and perhaps one of the most overlooked—is the coolant temperature sensor, sometimes abbreviated as the CTS. The In-Car Temperature sensor (ICTS) is a negative temperature coefficient sensor. How hot does your vehicle’s engine get during an average drive? - A 48 parts numbers range - An expert on Cooling Systems, Valeo … Choose Valeo water temperature sensors for: - The know-how of a worldwide key player. If you see the Check Engine sign light up, take your car in for professional servicing right away. All Rights Reserved. These problems do not necessarily mean an issue with the coolant temperature sensor. Let the engine run for a … Hint – if you can’t find a temperature sensor in your car – this article should help. The part, which is normally located near a vehicle’s thermostat near the base of … SELECT YOUR VEHICLE. As with any other component in your car, the sensor can go bad over time and fall into disrepair. This can cause a range of problems, including overheating the engine. When the signal is sent to the ECM, the computer adjusts the vehicles ignition timing, fuel flow, and other factors that trim or enhance performance based on the coolant temperature. Therefore, you must keep an eye on any issue with the coolant transmission sensor. The sensor detects the temperature of this coolant and feeds this information back in the form of an electrical current to the engine control unit (ECU). As a result, the engine will get to a point where it is very hot without any action from the car’s computer to trigger the fan or any ways to cool down the engine. The engine temperature sensor connects either to the temperature gauge or to the temperature indicator in the dashboard. This aspect of preventative maintenance can certainly save you some headaches and hassle in the long run. A DTC will be set if an abnormal reading occurs, P0116 for sensor performance, P0117 low input or P0118 for a high input. Labor cost depends on the number of hours mechanics spend fixing your issue and the hourly rate for these mechanics. Your car is a complex machine that relies on systems of interworking parts and pieces to collaborate together to produce the most effective conditions for optimal driving.

For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1 °C, the sensitivity is 1 cm/°C (it is basically the slope dy/dx assuming a linear characteristic). Related Article, Did you know In this case, the coolant might get contaminated; thus, you might need to get the entire system flushed. The readings from this sensor are then fed back to the Engine control unit (ECU), which uses this data to adjust the fuel injection and ignition timing.On some vehicles the sensor may also be used to switch on the electric cooling fan. From there, your vehicle’s computer will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature at an ideal level. The ECU then responds to a change in the temperature difference and readjusts the engines fuel injection. Like any other car’s fluid, the coolant liquid has to be in a certain amount to perform properly. In the end, never ignore problems related to the coolant temp sensor to avoid very high repair costs from severe damages. Related Article, Did you know In any vehicle, the engine has to stay within a specific range of temperature to work properly and avoid overheating. FIND A MEINEKE Upon measuring the coolant temperature, the sensor passes on a signal to the […] However, if there is a leak somewhere, the coolant level can get reduced and cause problems to the coolant temperature sensor. If the engine sustains any kind of trauma or damage, sensor replacement is. With AutoZone's great selection of coolant temperature sensors, you can easily find the perfect sensor for your exquisite … Choose the working place that works best for this job. https://resource-center.meineke.com/how-does-a-car-temperature-sensor-work If the car’s computer gets the wrong information about the engine’s temperature, causing problems with the fuel mixture adjustments. Input the amount of time, in minutes, that the car has been parked in those conditions. that when a battery is drained, it never fully regains its charge? Once the coolant temperature sensor measures the temperature, it will send a signal to the on-board control system. This device measures the temperature of the vehicle’s engine coolant. The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Different brands and car manufacturers have different ways of placing the coolant temperature sensor depending on the car design. Engine RPM Sensor. With the car getting older, the coolant temp sensor can get damaged or become faulty. How to test a coolant temperature sensor. The sensor will eventually need to be replaced altogether after time. The sensor keeps tabs on the operating temperature and alerts the on-car computer when there’s a potential problem. Generally speaking, if your sensor is not working, it will send a signal to the computer and your Check Engine light will be illuminated. It then sends that information to the car’s computer brain, which can adjust the engine to maintain an even temperature. Can be much simpler than that in coolant piece, keep in mind that it cool!
