Tire Pressure Sensor: Removal
- When replacing a wheel or tire, tire pressure sensors must be set up in one of the following ways:
- Remove the sensor from the old wheel and install it to the new wheel.
- Keep the same wheel with tire pressure sensor, and replace only the tire.
- Use a new wheel and sensor (the new sensor must be registered after installation).
- Remove wheel. Remove the valve core and cap, and release air from the tire. See Fig 1.
- After ensuring that air is sufficiently released, remove the nut and washer that is used to fix the tire pressure monitor valve sub-assembly and drop the sensor inside the tire.NOTE: Keep the removed cap, valve core, nut and washer.
- After dropping the tire pressure monitor valve sub-assembly into the tire, disengage the bead using the shoe of the tire remover. See Fig 2.NOTE: Be careful not to damage the tire pressure monitor valve sub-assembly due to interference between the sensor and tire bead.
- Remove the bead on the upper side in the usual operation.
- Take out the sensor from the tire, and remove the bead on the lower side as in usual operation.
- Remove the inner grommet from the tire pressure monitor valve sub-assembly.NOTE: Check that no cracks or damage is identified on the grommet. If so, replace the grommet together with the washer and nut.NOTE: Tire pressure sensor is powered by a lithium battery. When disposing sensor, remove battery and dispose of properly.
