Tire Pressure Sensor: Notes
CAUTION:
The use of tire sealants is strictly prohibited for vehicles equipped with the Tire Pressure Monitor (TPM) system. Tire sealants can clog tire pressure sensors.
CAUTION:
Before installing tire pressure sensor, ensure you have the correct sensor. Sensors can be easily identified by a white outline oval (with black center) insignia on the sensor body.
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 tire pressure sensor.
CAUTION:
The valve stem used on this vehicle is made from aluminum, and the core is nickel-plated brass. Retain original valve stem core for reinstallation. Do not substitute a valve stem made of a different material, as the different metals will cause corrosion.
CAUTION:
Any time a sensor is to be installed in a wheel, a new seal and washer must be installed on the stem 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.
NOTE:
If tires require leak-testing, a water test may be used to check for a leak around the sensor, as long as any water at the valve core is removed when procedure is completed. Water can be expelled from the core area by pushing in on the core for several seconds, allowing escaping air to drive out any moisture. Reinflate tire as necessary. Install original valve stem cap.
