The CHT temperature sensor is designed to measure the material temperature of the unit head. Anyway, the general rule is to open the hood and search for the front, center of motor (the upper radiator hose) in order to find a thermostat housing. Most often it is installed near the thermostat or radiator, in some cases the on-board computer uses the readings from both or one of the coolant sensors, depending on the vehicle brand and model.įor example, on 2008 the Ford F-150 its location is in front of the engine compartment. In order to repair it you should find the location first. Malfunctions are not quite obvious, as they coincide with those of some adjacent components. It is responsible for the correct functioning of the cooling system.Īlthough the device itself is quite simple and does not require expensive maintenance, it occasionally fails. The essence of its work is to give a signal to the motor control unit, which regulates the composition of the fuel mixture, as well as the speed of the crankshaft, as well as the angle of advance of the ignition. The element is a very important element responsible for the coolant temperature of the cooling system. Next, disconnect the wiring and turn the sensor with the key 19. All you have to do is drain the coolant down to a level just below the device position. You’ll also need a key for 19, an electric kettle and a container to drain the coolant. It is only important to have at hand a multimeter for measuring voltages (although it is not necessary to know this indicator for initial assessment) and resistances, as well as any device for measuring temperature. What’s very good is that modern ones make it possible to check almost at home.
