Tire Pressure Sensor: Notes
CAUTION:
On models with Dual Rear Wheels: The inner dually wheels contain a unique senor that is identified by "ID" (1) marked on the sensor housing. It is not compatible in other locations and must always be mounted as an inboard wheel. It has a standard rubber snap-in valve stem. See Figure.
CAUTION:
To prevent moisture and contamination from entering the valve stem, the cap used on this valve stem contains an "O" ring seal. Retain original valve stem cap for reuse. A regular valve stem cap cannot be used as a substitute. After inspecting or adjusting the tire pressure, always reinstall the valve stem cap. This will prevent moisture and dirt entry into the valve stem, which could damage the wheel rim sensor.
CAUTION:
Any time a sensor is to be reinstalled in a wheel, a new valve stem assembly must be installed to ensure air tight sealing. See Figure.
CAUTION:
DO NOT reuse sensor-to-wheel grommet. Always use a new grommet when installing a pressure sensor and properly torque the sensor nut.
