  Q: How do you replace the Engine Coolant Temperature (ECT) sensor for Toyota Camry and 2007 through 2015 Toyota Avalon?

  A: To replace the Coolant Temperature Sensor, start by ensuring the ignition key is in the OFF position. Then, remove the engine covers and drain approximately one gallon of coolant from the cooling system. Next, remove the air filter housing. Disconnect the electrical connector and unscrew the sensor. For four-cylinder models, the ECT sensor is located on the left end of the cylinder head, while for V6 models, it is located on the left end of the engine on the coolant crossover between the cylinder heads. Before installing the new sensor, wrap its threads with Teflon sealing tape to prevent leakage and thread corrosion. Finally, carefully handle the coolant sensor during installation, as damage to it can affect the operation of the entire fuel injection system.
