With the vehicle lifted properly and tire/wheel assembly removed, the following steps that should be followed to replace the Tire Pressure Sensor. Before you take the tire on; lay the cap of the sensor and its valve on a clean surface while the cap should be aluminum and the valve nickel-plated so that it is not easily corroded. When detaching the tire bead from the wheel, locate the bead breaking fixture 90 degrees away from the valve stem and locate the mounting/dismounting head parallel with the tire iron or pry bar could get inserted only slightly clockwise of the sensor body. Use the tire machine applying the tire/wheel assembly clockwise in the movement and transfer the tire-bead to the exterior side of the wheel rim, reiterate for the internal beads preceded to remove the tire from the wheel. If any of the tire sealant is there, wash all residual liquid sealant from the interior of the tire and wheel surfaces, and wash out the tire pressure sensor nut, as well as the sensor itself. For installation, clean the grommet sealing area of any dirt or debris, insert the sensor into the wheel hole with the air passage to the back of the wheel, install the sensor nut while aligning the body of the sensor with the inside surface of the wheel while tightening it to 7 Nm (62 inch lbs.). Position the mounting/dismounting head 180 degrees away from the valve stem and position the bead transition area 45 degrees counterclockwise of the valve stem before replacing the tire. Roll the tire/wheel assembly in a clockwise direction to move the tire bead to the inside of the wheel rim, followed by the other bead to the exterior, before the tire installation on the wheel. Not to mention that a service replacement tire pressure sensor is shipped in OFF mode, thus prohibiting the sensor's unique identification code from being learned into the memory of the antenna module; to turn the sensor away from OFF mode, spin the tire/wheel assembly at a rate of ring over 32 km/h (20 mph) for at least 10 seconds. Finally, mount the tire/wheel assembly to the vehicle, lower the vehicle, and teach the tire pressure sensors.
