Engine Water Temperature Sensor

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 most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.

Engine water temperature sensor.

How to control a coolant temperature sensor without removal. This video does not constitute or replace a real specialized technical man. These measurements produce essential data for the engine system of your vehicle. The coolant temperature sensor is what tells the car s computer what the engine s running temperature is.

Keep your engine cool regardless if the temperatures are skyrocketing outside by making sure your coolant temperature sensor is operating correctly. Based on this data the ecu also controls the additional functions such as switching on. Helping to ensure less fuel is supplied when the engine is warm or more when the engine is cold. Ecu in turn adjusts and regulates the fuel quantity ignition timing.

A functional coolant temperature sensor not only ensures a safer ride but it also prevents your vehicle from using more gas than necessary. On most vehicles the coolant temperature sensor cts can be found somewhere near the engine thermostat which allows it to function optimally. This will then translate to how the engine runs. When the sensor is functioning properly it will tell your on board computer if the temperature is too high alerting the driver that a problem exists.

But how does this car temperature sensor really work and what s its purpose. The engine temperature sensor informs the engine s ecu about the current ongoing variations in the engine temperature. Before the automated systems in vehicles this was the sole purpose of the temperature sensor. The coolant temperature sensor also known as the coolant temperature switch is the engine management system that monitors the temperature of the coolant and relays this information to the ecm.

How the temperature sensor works. Pentair 520272 air water solar temperature sensor with 20 feet cable replacement pool spa automation control systems and pump 4 6 out of 5 stars 310 23 99 23. The water or coolant temperature sensor t411973 is used to measure the temperature of the engine coolant which can then be fed back to the ecu to adjust the timing and fuel ignition. The tip of the cts is probably located right next to the engine coolant.
