GMC tire pressure monitor employs a sensor inside each tires valve stem. Resetting the GMC Sierra’s tire pressure sensor is necessary when changing tires or when tire pressure gets low, making the TPMS lights on. Most GMC vehicles have an automatic reset feature, but a manual reset is possible.
Reset Procedure
- Push down the lock and unlock button on your car keys fob at the same time. The horn will chirp twice.
- Unscrew the front left valve stem cap.
- Press the valve stem for some seconds to let the air out of the tire until the horn chirps. Replace the valve stem cap.
- Repeat the third procedure in the right-front, right-rear, left-rear wheels in that order. The system will reset, and TPMS lights will shut off.
This procedure applies to the GMC Sierra 2004- 2020. Resetting helps solve GMC tire pressure sensor problems. Examine the pressure in all four tires to ensure TPMS functions correctly, and tires have the recommended pressure.
