If your engine is overheating frequently.If the vehicle’s fuel consumption rises,.Possible symptoms of a damaged Coolant Temperature Sensor

An expert on Cooling Systems, Valeo offers a complete cooling systems selection with its thermostats, thermoswitches and water temperature sensors.

The know-how of a worldwide key player.

As the temperature of the engine changes, the potential difference output of the device also changes, and this can be measured by the engine's control unit. The device follows the principle of dependence of potential difference in temperature. There are two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard. In a nutshell, coolant temperature sensors monitor your engines temperature to ensure it doesnt overheat and can perform optimally. Depending on the car manufacturers, it is usually installed next to the thermostat or inside it. A standard two terminal NTC coolant sensor is generally located near the thermostat area to monitor changing coolant temperatures to assist the PCM in. The water temperature sensor enables the control unit to identify engine overheating or an unusual rise in temperature. Upon measuring the coolant temperature, the sensor passes on a signal to the car’s. Monitoring of the engine coolant is necessary as the engine’s fuel requirements are higher when it is cold, and lower when the engine is warm. A 48 parts numbers range - An expert on Cooling Systems, Valeo offers a complete cooling systems range with its thermostats, thermoswitches and water temperature sensors The coolant temperature sensor is responsible for monitoring the temperature of the coolant in your car engine. The Temperature sensor measures the coolant temperature & sends information to the ECU.Ĭhoose Valeo water temperature sensors for: - The know-how of a worldwide key player. If voltage is not present,Ĭheck if cooling fan fusible link 60A is open or not installed.Ĭheck if cooling fan relay is not installed or faulty.Ĭheck if the line between cooling fan relay and Cooling fan module is open.Valeo water temperature sensor range: Protect your engine and heat exchangers in extreme temperature conditions Check terminal 1 of cooling fan relay for battery voltage with ignition switch turned on. If no fault had been found with the wiring circuit, that would leave you with the PCM to check next.Ī missing power supply to the cooling fan would cause this as well. One of the most common cause would be a bad connection or ground circuit which should have been checked in the first instance.

When you reset a computer, you stop any software that’s running and erase the stored data. Coolant Temperature Sensor, ECT Temp Sensor D583 19022018 Compatible with Toyota Lexus - 4Runner Avalon Camry Corolla Highlander Matrix Prius RAV4 Sequoia Sienna Solara Tacoma Tundra Yaris ES350, More. How to control a coolant temperature sensor without removal.

You have replace the fan relay and that leaves you with a few other possibilities. Dorman Coolant Temperature Sensor and Switch Connector 645-164. 1.No, the coolant temperature sensor cannot be reset. Use the schematic diagram to find possible fault areas or components. The attached diagram gives brief description of the problem and possible causes. The car was leaking coolant at the coolant temperature sensor so I removed and replaced the temperature sensor o-ring and retaining clip with new parts from the dealership only to discover that that the leak persists. Guesswork is not a good idea for technical problems. Leak at Coolant Temp Sensor Retaining clip I have the same situation happening with my 04 Jettta TDI. To understand if the engine is running hot, a scan tool would allow you to read the coolant temperature of the engine.

It should be P0480 and not as that shown in your question.Įach code is specific to the cause of the problem and in this case it does not mention the engine coolant temperature as possible cause so the possibility of it being faulty is not high.

For a fault with the coolant temperature sensor, I believe you have typed in the wrong code.
