The first step to uninstall the Tire Pressure Warning Valve and Transmitter requires users to remove both front and rear wheels from the vehicle. You must first leave air out of the tire by taking off the valve core and cap before removing the nut and washer holding the tire pressure warning valve and transmitter so they can fall into the tire. Save all Tire Pressure Warning Valve and Transmitter hardware including caps, valves, cores, nuts, and washers because they will be needed for reassembly. Place the valve and transmitter inside the tire while the tire bead is disengaged but take caution to prevent damage to the valve and transmitter from encountering the tire bead. Remove both tire beads normally before pulling out the tire pressure warning valve and transmitter. Afterward, finish the bead removal on the lower rim. First inspect the grommet for fractures or breakage then get a new one if the inspection shows damage.

First, remove the front and rear wheels.

Set the wheel disc on the mounting machine and install the lower tire bead, positioning the main body of the valve and transmitter within the designated shaded area.

Begin by removing the front and rear wheels.

Extract the tire pressure warning valve and transmitter from the tire and remove the bead on the lower side as well.

Inspect the tire and register the transmitter ID, followed by inspecting the tire pressure warning system.

The tire pressure sensor system includes the tire pressure warning valve and transmitter.
