This procedure covers the replacement of a Tire Pressure Monitoring System (TPMS) sensor on a 2014-2018 Chevrolet Silverado 1500, including tire removal, sensor replacement, and system relearn.

Warnings

Tools required

Parts

• TPMS sensor (GM 13581561 or equivalent) × 1 — GM 13581561
• TPMS valve core × 1 — Use OEM specification
• TPMS grommet/seal kit × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Loosen wheel lug nuts on the wheel with the faulty TPMS sensor before raising vehicle
3. Raise vehicle with floor jack and support securely on jack stands
4. Ensure TPMS relearn tool is charged and ready, or have access to compatible scan tool

Procedure

1. 1

   Remove wheel
   Remove the lug nuts completely and take off the wheel. Note which position the wheel was in (LF, RF, LR, RR) as this will be needed during the relearn process.
2. 2

   Deflate tire completely
   Remove the valve cap and use a valve core tool to completely deflate the tire. Remove the valve core and set aside if reusing. Ensure tire is completely deflated before proceeding to bead breaking.
3. 3

   Break tire bead and remove tire from wheel
   Using a tire machine or manual bead breaker, break both beads of the tire away from the wheel rim. Carefully dismount the tire from the wheel, taking care not to damage the wheel finish or tire bead.
4. 4

   Remove old TPMS sensor
   Locate the TPMS sensor mounted to the valve stem hole inside the wheel. The sensor is typically held by a hex nut on the valve stem. Unscrew the retaining nut and carefully pull the sensor and valve stem assembly through the wheel from the inside. Note the orientation of the sensor for proper installation of the new unit.
5. 5

   Install new TPMS sensor
   Install the new grommet/seal onto the new TPMS sensor valve stem. Insert the sensor assembly through the wheel valve hole from the inside. Thread on the retaining nut finger-tight, then tighten to ensure a secure, leak-free seal. Do not overtighten as this can damage the sensor body or grommet. Typical tightening is 4-6 lb-ft but verify with sensor manufacturer specifications.
6. 6

   Mount tire back onto wheel
   Place the tire back onto the wheel, ensuring proper bead seating. Use tire machine or manual tire irons to mount the tire onto the rim. Ensure both beads are properly seated in the drop center of the wheel before inflating.
7. 7

   Inflate tire and check for leaks
   Install the valve core into the new TPMS sensor valve stem. Inflate the tire to the recommended pressure as shown on the driver door jamb placard (typically 35 PSI front, 35 PSI rear for this vehicle). Apply soapy water solution around the valve stem to check for leaks. Verify tire bead is properly seated all around the wheel.
8. 8

   Reinstall wheel on vehicle
   Lift the wheel and tire assembly onto the hub. Thread on all lug nuts by hand to prevent cross-threading. Using a torque wrench, tighten lug nuts in a star pattern to specification.
   Torque spec

   Wheel Lug Nuts140 Nm (103 lb-ft)
9. 9

   Lower vehicle
   Raise the vehicle slightly to remove jack stands, then lower the vehicle completely to the ground. Perform a final torque check on all lug nuts in a star pattern with vehicle weight on the ground.
10. 10

    Perform TPMS relearn procedure
    Turn ignition to ON position (engine off). Using the TPMS relearn tool, activate the relearn mode through the vehicle's Driver Information Center or use a scan tool to initiate relearn mode. Starting with the left front tire, hold the TPMS tool against the tire sidewall near the valve stem and activate. Wait for horn chirp confirmation. Repeat for right front, right rear, and left rear in that order. Turn ignition off. Start engine and verify TPMS light is off and all tire pressures display correctly on instrument cluster.

Reassembly

1. Ensure all lug nuts are torqued to specification in star pattern
2. Verify tire pressures match door jamb specifications
3. Confirm TPMS warning light is extinguished and all tire pressures read correctly on instrument cluster

Verification

• Start the vehicle and observe that the TPMS warning light illuminates briefly during bulb check then goes off
• Check Driver Information Center or instrument cluster to verify all four tire pressures are displaying and reading correctly
• Drive vehicle at speeds above 25 mph for at least 10 minutes to confirm TPMS system is functioning and warning light remains off
• Verify no air leaks from the new sensor valve stem by checking tire pressure after 24 hours
