This procedure covers the replacement of a TPMS (Tire Pressure Monitoring System) sensor on a 2018-2024 Honda Accord with the 1.5L turbo engine.

Warnings

Tools required

Parts

• TPMS sensor × 1 — Use OEM Honda TPMS sensor or compatible aftermarket
• TPMS valve core × 1 — Included with most TPMS sensors
• TPMS grommet/seal × 1 — Replace if damaged or cracked

Preparation

1. Park vehicle on level ground and engage parking brake
2. Locate the affected wheel with the faulty TPMS sensor (use TPMS diagnostic tool to identify which sensor has failed)
3. Loosen wheel lug nuts slightly while vehicle is on the ground
4. Safely raise vehicle with floor jack and support on jack stands
5. Remove wheel completely

Procedure

1. 1

   Remove wheel from vehicle
   With vehicle safely supported on jack stands, remove the wheel lug nuts completely and remove the wheel from the hub. Set wheel on a clean work surface for tire dismounting.
2. 2

   Deflate tire completely
   Using a valve core removal tool, remove the valve core from the TPMS sensor valve stem to completely deflate the tire. Ensure all air pressure is released before attempting to break the bead.
3. 3

   Break tire bead
   Use a bead breaker or tire machine to break both the inner and outer beads of the tire away from the wheel rim. Work around the entire circumference to ensure the bead is completely separated on both sides.
4. 4

   Remove tire from wheel
   Using a tire mounting machine or manual tire spoons, carefully dismount the tire from the wheel. Work slowly near the TPMS sensor location to avoid damaging the sensor during removal. Note the rotational position of the old sensor for reference.
   ⚠Use plastic tire spoons or protective covers when working near the TPMS sensor to prevent damage to the sensor body.
5. 5

   Remove old TPMS sensor
   From inside the wheel, remove the retaining nut or clip securing the TPMS sensor to the wheel. Carefully pull the sensor and valve stem through the wheel rim hole from the outside. Inspect the grommet/seal for damage.
6. 6

   Install new TPMS sensor
   Install a new grommet/seal onto the new TPMS sensor valve stem if required. Insert the sensor valve stem through the wheel rim hole from the outside. From inside the wheel, install the retaining nut or clip and tighten by hand only - do not over-torque the sensor mounting hardware. Ensure the sensor body is positioned correctly according to manufacturer specifications.
   ⚠Hand-tighten TPMS sensor mounting nut only. Over-tightening can crack the sensor body or damage internal components.
7. 7

   Remount tire onto wheel
   Using the tire mounting machine or manual tire spoons, carefully mount the tire back onto the wheel rim. Ensure the tire bead is properly seated in the drop center of the rim. Work carefully to avoid contacting or damaging the newly installed TPMS sensor.
8. 8

   Seat tire bead and inflate
   Install a new valve core into the TPMS sensor valve stem. Inflate the tire to seat both beads properly on the rim. You may hear audible pops as the beads seat. Once beads are seated, adjust tire pressure to the specification shown on the driver door jamb label (typically 32-35 PSI for the Honda Accord).
9. 9

   Reinstall wheel on vehicle
   Mount the wheel back onto the hub, ensuring it sits flush against the mounting surface. Install all lug nuts by hand first. Torque the lug nuts to specification using a star pattern to ensure even seating of the wheel.
   Torque spec

   Wheel Lug Nuts140 Nm (103 lb-ft)
10. 10

    Program TPMS sensor
    Use a TPMS activation tool or Honda HDS (Honda Diagnostic System) to program the new TPMS sensor to the vehicle. Follow the tool manufacturer's instructions for your specific programming tool. The sensor must transmit its unique ID to the vehicle's TPMS control module. Some sensors are automatically learned during a drive cycle, while others require manual programming.

Reassembly

1. Lower vehicle from jack stands
2. Perform final torque check on wheel lug nuts with vehicle on ground using star pattern
3. Clear any TPMS fault codes from vehicle computer using diagnostic tool if necessary

Verification

• Start the vehicle and verify the TPMS warning light turns off after a few seconds of driving (may require up to 10 minutes of driving)
• Use a TPMS scan tool to verify the new sensor is transmitting properly and the vehicle is receiving the signal
• Check tire pressure with a gauge to confirm it matches the door jamb specification
• Verify all four TPMS sensors are reporting correct pressures on the instrument cluster display if equipped
• Test drive the vehicle and confirm the TPMS light does not illuminate
