This procedure relearns the Tire Pressure Monitoring System (TPMS) sensors on a 2021 Ford Transit 3.5L V6 EcoBoost AWD after tire rotation, sensor replacement, or pressure adjustment.
Warnings
ℹ️TPMS relearn must be performed with the vehicle stationary and ignition on, engine off.
ℹ️Ensure all tires are inflated to the correct pressure listed on the driver door jamb placard before beginning the relearn procedure.
⚠Do not perform TPMS relearn while vehicle is in motion or with ignition in accessory mode.

Preparation
- Park vehicle on level ground and engage parking brake
- Verify all four tires plus spare (if equipped with TPMS sensor) are inflated to manufacturer specifications on door placard
- Ensure TPMS relearn tool has fresh batteries and is functioning properly
- Locate TPMS sensor valve stems on all four wheels (and spare if applicable)
Procedure
- 1Access TPMS Training ModeTurn ignition to ON position (engine off). Press and release the brake pedal. Turn ignition OFF, then back to ON position three times, ending in ON position. Press and release brake pedal again. Turn ignition OFF. This cycle prepares the system for relearn mode entry.
- 2Enter TPMS Relearn ModeTurn ignition to ON position (engine off). Complete the ignition and brake-pedal key-cycle sequence from Step 1 to enter TPMS Training Mode. When training mode is successfully entered, the horn will sound once and the TPMS indicator light will begin flashing to confirm relearn mode is active. If the horn does not sound, repeat the ignition/brake pedal cycle in step 1.
- 3Activate Left Front SensorStarting with the left front tire, place the TPMS relearn tool at the valve stem location against the tire sidewall. Activate the tool according to manufacturer instructions to trigger the sensor. When successfully activated, the horn will sound once. Wait for the horn confirmation before proceeding to the next wheel.
- 4Activate Right Front SensorMove to the right front tire. Place the TPMS relearn tool against the tire sidewall near the valve stem and activate. Wait for the single horn confirmation before proceeding.
- 5Activate Right Rear SensorMove to the right rear tire. Place the TPMS relearn tool against the tire sidewall near the valve stem and activate. Wait for the single horn confirmation before proceeding.
- 6Activate Left Rear SensorMove to the left rear tire. Place the TPMS relearn tool against the tire sidewall near the valve stem and activate. Wait for the single horn confirmation. After the left rear sensor is successfully learned, the horn will sound twice to indicate the relearn procedure is complete.
- 7Exit Relearn ModeTurn the ignition OFF after hearing the double horn confirmation. The TPMS warning light should extinguish within 2 minutes of driving, or immediately if using the instrument cluster to verify sensor status.
Reassembly
- No disassembly is required for this procedure
Verification
- Turn ignition to ON position and verify the TPMS warning light is not illuminated on the instrument cluster
- Navigate to the tire pressure display on the instrument cluster and confirm all four tire pressures are displaying correctly
- Drive vehicle for 2-5 minutes at speeds above 20 mph to allow the system to fully initialize and verify all sensors are communicating
- Verify no TPMS fault codes are present using instrument cluster diagnostics or scan tool if available
