This procedure covers the replacement of a Tire Pressure Monitoring System (TPMS) sensor on a 1994-2007 Dodge Ram 2500 with 5.9L Cummins diesel engine.

Warnings

⚠TPMS sensors on 1994-2007 Ram 2500 were not factory-installed. This procedure assumes an aftermarket TPMS system has been added. Verify system is present before proceeding.

ℹ️Ensure vehicle is on stable, level ground before jacking. The weight of the 4WD Cummins diesel configuration requires proper support.

⚠Deflate tire completely before breaking the bead to avoid damaging the TPMS sensor during disassembly.

Preparation

Park vehicle on level, solid surface and set parking brake
Loosen lug nuts on the wheel with the faulty TPMS sensor while vehicle is still on the ground
Identify which wheel has the faulty sensor using the TPMS warning light or programming tool diagnostic mode
Gather all tools and the replacement TPMS sensor

Procedure

1
Raise and support vehicle
Position floor jack under the appropriate frame rail or axle housing near the wheel requiring service. Lift vehicle and support with jack stands at a secure frame point. Remove lug nuts completely and remove the wheel and tire assembly from the vehicle.
2
Deflate tire completely
Use the valve core removal tool to completely remove the valve core from the TPMS sensor valve stem. Allow all air pressure to escape from the tire. Ensure tire is fully deflated before proceeding to bead breaking.
3
Break tire bead
Position the tire with the TPMS sensor location away from the bead breaker. Break both tire beads from the wheel rim using a bead breaker or tire machine. Work carefully to avoid damaging the sensor during this process.
4
Remove tire from wheel
Using tire spoons or a tire machine, carefully demount the tire from the wheel. Take care when working near the TPMS sensor valve stem area to avoid bending or breaking the sensor body or mounting hardware.
5
Remove old TPMS sensor
Locate the TPMS sensor mounted to the wheel rim. Remove the retaining nut from the valve stem on the outside of the wheel. Carefully pull the sensor and valve stem assembly through the wheel rim from the inside, removing it completely.
6
Install new TPMS sensor
Insert the new TPMS sensor valve stem through the valve stem hole in the wheel rim from the inside. Ensure the sensor body is properly oriented and seated against the rim. Thread the new retaining nut onto the valve stem from the outside and hand-tighten securely. Do not overtighten as this may damage the sensor or stem.
7
Remount tire to wheel
Position the tire back onto the wheel, aligning carefully to avoid striking the TPMS sensor. Use tire spoons or tire machine to seat both beads back onto the rim. Ensure beads are properly positioned in the bead seat area around the entire circumference.
8
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 listed on the door placard (typically 65-80 PSI for Ram 2500 depending on tire size and load rating). Apply soapy water solution around the valve stem and bead areas to check for air leaks. Verify beads are properly seated.
9
Program TPMS sensor
Because these trucks were not factory-equipped with TPMS, any system present is aftermarket. Use the programming/pairing method specified by the aftermarket TPMS system manufacturer to register the new sensor to the aftermarket receiver/display unit. There is no factory OBD-based relearn on these vehicles.
10
Reinstall wheel and lower vehicle
Mount the wheel and tire assembly back onto the vehicle hub. Thread all lug nuts by hand until snug. Lower the vehicle until the tire just contacts the ground but the full weight is still on the jack stands. Tighten lug nuts in a star pattern. Lower vehicle completely and perform final lug nut tightening to 135 ft-lbs (verify against year-specific factory spec, typically 130-145 ft-lbs for the 8-lug Ram 2500) in a star pattern.

Reassembly

Ensure all lug nuts are properly torqued to 135 ft-lbs in a star pattern
Verify tire pressure matches the vehicle door placard specification
Double-check that the new TPMS sensor is properly programmed to the vehicle

Verification

Start the vehicle and verify the TPMS warning light extinguishes after a few seconds or after driving briefly
Use the TPMS programming tool to confirm the new sensor is transmitting and being received by the vehicle system
Drive the vehicle at low speed and verify proper TPMS operation and that the tire holds air pressure
Recheck tire pressure after 24 hours to ensure no slow leaks are present
