Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is turned off.
Disconnect the negative battery terminal for safety.

2. Inspect and Inflate Tires

Check the tire pressure of all four tires using a tire pressure gauge.
Inflate tires to the recommended pressure as indicated on the driver’s door jamb sticker.
Inspect each tire for visible damage or wear.

3. Check and Replace TPMS Sensors

Remove the tire from the wheel using a tire changing machine.
Inspect the TPMS sensor for any visible damage.
If damaged, replace the sensor with a new one. Ensure the correct part number is used for the 2018-present Toyota Camry.
Reinstall the tire onto the wheel and balance it.

4. Reset the TPMS

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Press and hold the TPMS reset button (located under the steering wheel or in the glove compartment) until the TPMS light blinks three times, then release the button.
Drive the vehicle for a short distance (approximately 10 minutes) to allow the system to recalibrate.

5. Final Inspection

Confirm that the TPMS warning light is no longer illuminated.
Recheck tire pressures to ensure they remain at the correct levels.
