The cooling system parts are built to last for long years to come, but as they are exposed to the flow of coolant that contains aggressive chemicals, malfunctions are possible. So, when these parts are faulty or eventually wear out, your engine will stop function properly, and there will be risk of overheating. Without the data that the switches and sensors collect, the ECU wouldn’t be able to correctly regulate such functions as ignition and fuel supply. Coolant temperature sensors and switches are responsible for measuring the engine temperature: once the temperature reaches a specific threshold, the ECU gets this information and activates the radiator fan, which continues to run till the engine cools down and its temperature drops to a predetermined level. Seemingly insignificant and sometimes overlooked, the switches and sensors it uses are actually crucial parts, as they are involved in system management. Sealed Anti-Static Protective Packaging ensures that electrical components are not damaged during shipping.All automobile systems that are responsible for energy transfer rely on switches, sensors, or relays, and the engine cooling system is no exception.Holstein Parts uses only the highest quality materials, manufactured to exacting standards to provide long-term function and performance.Holstein Parts Coolant Temperature Sensors offer superior coverage for domestic and import applications.What makes Holstein Parts Coolant Temp Sensors the Best? Signs of a coolant temperature sensor failure could include poor fuel economy, irregular temperature readings, an overheating engine, and /or your check engine light coming on.
Coolant temperature sensor how to#
How to determine if a Coolant Temperature Sensor is failing? The sensor becoming corroded or poor electrical connection to the ECU If your car’s computer senses a problem with the signal your sensor is sending, it may trigger the check engine light. You may see your check engine light come on if your coolant temperature sensor is failing or has failed. While some vehicles utilize an auxiliary temperature sensor to. Will a malfunctioning Coolant Temperature Sensor cause a check engine light? One of the most severe symptoms of coolant temperature sensor failure is engine overheating. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath the air intake pipe. However, depending on the model of your car, you might also find the temperature sensor attached to a cylinder head. Most of the temperature sensors are usually located close to the thermostat housing. The coolant temperature sensor will be located directly behind the coolant pipe. For you to locate the temperature sensor, you have to open your vehicle. Where is the Coolant Temperature Sensor located? What does the Coolant Temperature Sensor do?Ī coolant temperature sensor is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off. 3 Year / 36,000 Mile Warranty on all Holstein Parts Coolant Temp Sensors.Holstein Parts Coolant Temp Sensors offer superior coverage for domestic and import applications.Holstein Parts uses only the highest quality materials and engineering for parts that are truly built to match or exceed the OE part.The computer will also scale back engine performance settings if it detects that the engine temperature is too high in order to protect the engine from possible damage due to overheating.īecause temperature plays such a vital role in engine performance calculations, a problem with a coolant temp sensor can quickly translate into engine performance issues. This signal is then sent to the electronic control unit (ECU) so that changes can be made to the engine’s timing and air/fuel mixture for optimal performance, as engines require more fuel when they are cold and less fuel when they are fully warmed up. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant. The Coolant Temperature Sensor, also known as the coolant temperature switch, is an engine management system sensor used to monitor the engine coolant’s temperature.
