corrosion that forms when dissimilar metals come in contact. See the service parts
guide for the correct GM part numbers to order and use.
Q: Can the grommet (and washer) be replaced?
A: The grommet (and washer) can and should be replaced if the sensor is removed
from the wheel. The rubber grommet provides the air seal in the valve stem opening,
and a new one should be used to ensure a fresh seal after each service. See the
service parts guide for the correct GM part numbers to order and use.
Q: Can the rubber valve stem be replaced by itself?
A: The rubber valve stem is attached to the sensor electronics by a TORX screw. The
valve can and should be replaced whenever the sensor is removed from the wheel.
See the service parts guide for the correct GM part numbers to use.
Q: Can the sensor be cleaned with a sharp pin?
A: NEVER use a sharp object to clean the pressure port of the sensor; it can be
damaged and lead to part failure. If the dirt/grime/obstruction cannot be removed
with a cloth, replace the sensor.
Q: How long will the sensor's battery work?
A: The sensor is designed to last for 10 years or 150,000 miles
(240,000 kilometers).
Q: Are tire pressure sensors compatible with aftermarket tire
sealants?
A: Tire pressure sensors are not compatible with commercially-available tire
sealants. Tire sealant materials can clog the pressure port of the sensor, and lead to
inaccurate pressure readings and improper Low Tire warnings. Additionally, some
sealant products use materials that can degrade the protective potting material that
covers the sensor's electronics.
Q: Are tire pressure sensors compatible with GM Inflator Kits?
A: While tire pressure sensors are NOT compatible with commercially-available
sealants, they HAVE been tested and ARE compatible with GM Inflator Kits and the
sealant that they use. After inflator kit use, the sensor should be inspected for any
damage, and replaced/cleaned as needed.
Q: Are tire pressure sensors compatible with nitrogen inflation?
A: Tire pressure sensors are compatible with nitrogen inflation (normal air is already
78% nitrogen).
Q: How do changing outside temperatures affect tire pressure?
