Description

DESCRIPTION

CAUTION: The use of tire sealants is strictly prohibited for vehicles equipped with the Tire Pressure Monitoring system. Tire sealants can clog tire pressure sensors.

CAUTION: Tire pressure sensor valve stem caps and cores are specially designed for the sensors. Due to risk of corrosion, do not use a standard valve stem cap or core in a tire pressure sensor in place of the original equipment style sensor cap and core.

CAUTION: Do not attempt to install a tire pressure sensor in a steel wheel or aftermarket wheel. Use tire pressure sensors in original style factory wheels only.

A tire pressure sensor/transmitter is installed in each wheel of this vehicle as part of the tire pressure monitoring system. A special valve stem incorporated into each tire pressure sensor/transmitter attaches it to the wheel.

VALVE STEM CORE AND CAP

On this vehicle, the valve stem is part of the tire pressure sensor/transmitter and is used as its antenna. If corrosion were to develop in the valve stem, it would affect the ability of the tire pressure sensor/transmitter to send the radio frequency signal to the TPM module.

The valve stem used on this vehicle is made from aluminum. Corrosion of aluminum will be caused by putting a dissimilar metal in contact with it. To prevent this type of corrosion from developing within the valve stem, the core of the valve stem is made of a compatible metal and is specially coated.

For this reason, a standard valve stem core must never be installed in this valve stem. If the core of the valve stem is removed when servicing the tire, the original valve stem core must be reinstalled. If the valve stem core needs to be replaced, it must be replaced with an original equipment valve stem core.

The valve stem caps used on this vehicle are specially designed for their use on the valve stem of the tire pressure sensor/transmitter. Each valve stem cap has an O-ring in the upper end of the valve stem cap to provide a positive seal at the end of the valve stem. This keeps dirt, contamination and corrosion out of the valve stem caused by moisture. As listed earlier, these conditions can affect the ability of the tire pressure transmitter to send the radio frequency signal to the TPM module.
