This procedure covers the replacement of one or more TPMS (Tire Pressure Monitoring System) sensors in the wheels of a 2015-2020 Ford F-150 with 5.0L V8 engine.

Warnings

Tools required

Parts

• TPMS sensor × 1 — Motorcraft TPM-19 or equivalent 433MHz sensor
• TPMS valve stem nut × 1 — Use OEM specification
• TPMS service kit (valve core, cap, stem seal) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Chock the wheels that will remain on the ground
3. Loosen wheel lug nuts on the wheel with the faulty TPMS sensor while vehicle is still on the ground
4. Identify which TPMS sensor requires replacement using TPMS diagnostic tool or fault code from instrument cluster

Procedure

1. 1

   Raise vehicle and remove wheel
   Raise the vehicle using a floor jack at the appropriate jacking point for the wheel being serviced. Secure the vehicle on a jack stand rated for the vehicle weight. Remove the wheel lug nuts completely and remove the wheel from the hub.
2. 2

   Deflate tire completely
   Remove the valve cap and use a valve core removal tool to extract the valve core from the TPMS sensor valve stem. Allow the tire to deflate completely. Confirm tire is fully deflated before proceeding to bead breaking.
3. 3

   Break tire bead
   Using a bead breaker or tire machine, break the tire bead on both sides of the wheel. Work around the circumference to ensure the bead is fully separated from the wheel rim on both the outer and inner beads.
   ⚠Keep hands and body clear of pinch points between tire and wheel during bead breaking.
4. 4

   Remove tire from wheel
   Mount the wheel on a tire machine or use tire spoons to carefully pry the tire over the wheel rim. Work the outer bead off first, then remove the inner bead. Take care not to damage the wheel finish or tire bead during removal.
5. 5

   Remove old TPMS sensor
   Locate the TPMS sensor mounted to the valve stem hole on the inside of the wheel. Remove the retaining nut from the valve stem on the outside of the wheel. Push the sensor and valve stem assembly through the wheel rim from the outside and remove it from the wheel. Inspect the valve stem hole for damage or corrosion.
6. 6

   Install new TPMS sensor
   Insert the new TPMS sensor valve stem through the valve stem hole from the inside of the wheel. Ensure the sensor body is oriented correctly (angled away from the center of the wheel). Thread the valve stem nut onto the valve stem from the outside and hand tighten. Torque the nut to specification, being careful not to over-torque and damage the sensor body.
   ⚠Do not over-torque TPMS valve stem nut. Typical torque is 35-45 in-lb (4-5 Nm). Follow sensor manufacturer specifications.
7. 7

   Reinstall tire on wheel
   Position the tire onto the wheel, ensuring proper directional orientation if applicable. Lubricate the tire beads with approved tire mounting lubricant. Using a tire machine or tire spoons, work the inner bead over the wheel rim first, then mount the outer bead. Ensure the TPMS sensor is not contacted or damaged during tire installation.
8. 8

   Seat tire beads and inflate
   Install a new valve core into the TPMS sensor valve stem using the valve core tool. Inflate the tire slowly, monitoring to ensure both beads seat properly on the wheel rim. You should hear distinct pops as each bead seats. Inflate to the pressure specification listed on the driver door jamb placard (typically 35 psi front and rear for F-150).
   ⚠Stand clear of tire sidewall during initial inflation. If beads do not seat by 40 psi, deflate and reposition tire.
9. 9

   Balance wheel assembly
   Mount the wheel and tire assembly on a wheel balancer and balance according to balancer manufacturer instructions. Apply balance weights as needed to achieve proper balance. This step may be performed at a tire shop if balancing equipment is not available.
10. 10

    Reinstall wheel
    Position the wheel onto the hub, aligning the lug nut holes. Thread all lug nuts onto the studs by hand to prevent cross-threading. Use a torque wrench to tighten the lug nuts in a star pattern to specification.
    Torque spec

    Wheel Lug Nuts140 Nm (103 lb-ft)
11. 11

    Program TPMS sensor
    Using a TPMS programming tool compatible with Ford vehicles, activate the new sensor and program it to the vehicle. Follow the tool manufacturer instructions for the programming sequence. For 2015-2020 F-150, this typically involves entering learn mode through the instrument cluster menu or using a scan tool, then triggering each sensor in the correct sequence (LF, RF, RR, LR).

Reassembly

1. Lower vehicle from jack stand using floor jack and remove jack stand
2. Lower vehicle completely to the ground
3. Perform final torque check on wheel lug nuts in star pattern after vehicle is on the ground
4. Install valve stem cap on TPMS sensor valve stem

Verification

• Start the vehicle and verify the TPMS warning light extinguishes after a few seconds of driving
• Use a TPMS diagnostic tool to confirm the new sensor is communicating properly and reporting correct pressure
• Check tire pressure with a manual gauge to confirm it matches the TPMS reading and vehicle specification
• Drive the vehicle for 10-15 minutes above 20 mph to ensure all sensors report to the system
• Verify no TPMS fault codes are present in the instrument cluster or body control module
