TPM Sensor / Wheel Warranty Reviews
During the last warranty review period it was noted that wheels being returned under the GM New Vehicle Warranty were being shipped back to General
Motors with the TPM sensor still attached to the wheel. Return rates ran as high as 60% with the TPM sensors still attached. Operational TPM sensors
should not be returned to GM and are to be transferred to replacement wheels if they become necessary.
Important:
Operational TPM Sensors that are returned under warranty to General Motors will be charged back to the dealer.Sensors have a 10 year /150,000
mile (240,000 km) battery life, and should be transferred if one or more wheels are replaced.
TPM Valve Stem / Grommet (0-ring) Replacement
When the TPM sensors are transferred to new wheels you should replace the component used to seal the TPM sensor stem to the wheel. On sensors with
an aluminum stem and visible nut on the outside of the wheel a replacement grommet (0-ring) should be used to assure a proper seal. The sensor
retaining nut (except Aveo) should be tightened to 7 N.m (62 lb in) for all vehicles except Pontiac Vibe (4.0 N.m (35.4 lb in)).
Important:
^
DO NOT overtorque the retaining nut.
Notice:
^
Factory installed TPM Sensors come with plastic aluminum or nickel-plated brass stem caps. These caps should not be changed. Chrome plated steel
caps may cause corrosion of aluminum valve stems due to incompatibility of the metals.
On current style sensors the entire rubber stem is replaceable. The service interval on the revised TPM sensor with replaceable stem is the same as for
any other traditional valve stem. Replace the stem at the time of tire replacement sensor transfer or whenever air seepage is suspected at the valve stem.
When replacing the valve stem tighten the screw to 1.3 N.m (11.5 lb in).
For either style of TPM sensor see the service parts guide for the correct GM part numbers to order and use.
