TPMS Sensor

This procedure covers the replacement of a Tire Pressure Monitoring System (TPMS) sensor on a 2007 Ram 3500, including sensor removal, installation, and relearning.

Warnings

Tools required

Parts

• TPMS sensor × 1 — Mopar 56053031AD or equivalent 315MHz sensor
• TPMS valve service kit × 1 — Includes valve core, cap, and grommet

Preparation

1. Park vehicle on level, solid ground and engage parking brake
2. Identify which wheel has the faulty TPMS sensor using a TPMS scan tool or instrument cluster display
3. Loosen lug nuts on the affected wheel while vehicle is still on the ground
4. Raise vehicle with floor jack and support securely on jack stands rated for the vehicle weight
5. Remove lug nuts and remove the wheel from the hub

Procedure

1. 1

   Deflate tire completely
   Remove the valve cap and use the valve core tool to completely remove the valve core from the TPMS sensor. Allow all air to escape from the tire. Store the valve core if the sensor is being reused, otherwise discard.
2. 2

   Break tire bead
   Using a tire mounting machine or manual bead breaker, break both beads of the tire from the wheel rim. Work carefully around the circumference of the tire on both sides to fully release the beads from the rim.
3. 3

   Remove tire from wheel
   Using a tire mounting machine or tire spoons, carefully work the top bead over the rim, then remove the bottom bead. Take care not to damage the rim or contact the TPMS sensor location with tools during this process.
4. 4

   Remove old TPMS sensor
   Locate the TPMS sensor mounted to the valve stem inside the wheel. Remove the retaining nut from the backside of the wheel that secures the sensor valve stem. Pull the sensor and valve stem assembly through the rim hole from the inside. Inspect the sensor mounting hole in the rim for damage or corrosion.
5. 5

   Install new TPMS sensor
   Install the new rubber grommet from the service kit onto the new TPMS sensor valve stem. Insert the sensor valve stem through the rim hole from the inside. Thread the retaining nut onto the valve stem from the outside and tighten by hand. Position the sensor body so it will not contact the tire during installation.
6. 6

   Tighten sensor mounting nut
   Using a torque wrench or tightening by feel, secure the TPMS sensor valve stem nut. Tighten to the sensor manufacturer's specified torque (commonly around 44-62 in-lbs for clamp-in style sensors). Verify the exact spec for the installed sensor. Do not overtighten as this can damage the sensor or grommet. Do not overtighten as this can damage the sensor or grommet. Ensure the sensor hangs properly into the drop center of the wheel.
7. 7

   Reinstall tire on wheel
   Apply tire mounting lubricant to both tire beads. Position the tire on the wheel with the bottom bead over the rim edge. Using tire mounting machine or tire spoons, work the top bead over the rim edge, being extremely careful to avoid contacting or damaging the TPMS sensor.
8. 8

   Inflate and seat tire beads
   Install the new valve core from the service kit into the TPMS sensor valve stem and tighten securely. Inflate the tire to seat both beads on the rim. You should hear audible pops as each bead seats. Inflate to the vehicle's recommended tire pressure as shown on the door jamb placard. Refer to the placard for the exact front and rear pressures for this specific vehicle and tire configuration.
9. 9

   Check for leaks and balance wheel
   Spray soapy water around the valve stem and bead areas to check for air leaks. If no leaks are present, install the valve cap. Have the tire and wheel assembly balanced on a tire balancing machine before reinstalling on the vehicle.
10. 10

    Reinstall wheel on vehicle
    Mount the wheel onto the hub, ensuring it seats properly. Thread all lug nuts on by hand. Tighten lug nuts to the factory spec (commonly 145 ft-lbs for 2007 Ram 3500) using a torque wrench in the manufacturer-specified sequence. Verify the exact torque and pattern for this vehicle, especially for dual-rear-wheel (dually) configurations.
11. 11

    Perform TPMS relearn procedure
    Using a TPMS diagnostic tool or the vehicle's built-in relearn procedure, program the new sensor to the vehicle. For 2007 Ram 3500, use a TPMS activation/scan tool to trigger each sensor and register it to the vehicle via the appropriate relearn procedure. Verify the correct relearn method for this vehicle, as it typically requires a TPMS tool rather than a dashboard reset button. Alternatively, use a TPMS tool to activate each sensor and program it to the correct wheel position.

Reassembly

1. Remove jack stands and lower vehicle completely to the ground
2. Perform final lug nut torque check with vehicle weight on the ground in a star pattern
3. Verify tire pressure is correct for all four tires per door jamb specifications

Verification

• Start the vehicle and verify the TPMS warning light goes off after a few seconds of driving
• Use a TPMS scan tool to verify all four sensors are transmitting and reporting correct pressures
• Check the instrument cluster or EVIC display to confirm all tire pressures are reading correctly
• Drive vehicle at speeds above 15 MPH for several minutes to ensure the system fully recognizes the new sensor
