Identify the Cause of the TPMS Warning Light
 

• • First, determine why the Tire Pressure Monitoring System (TPMS) warning light is on. It could be due to low tire pressure in one or more tires, a change in temperature, or a fault with the TPMS sensor.

 
Check and Adjust Tire Pressure
 

• • Ensure all tires are inflated to the recommended pressure level specified on the door placard, typically found on the driver’s side door jamb. Use a reliable tire pressure gauge to check the current pressure and adjust as needed.

 
Initialize the TPMS
 

• • Once the tire pressures are adjusted, the TPMS may need to be reset, or initialized. For the 2021 Toyota Camry, first ensure the car is in park and the ignition is turned to the "ON" position without starting the engine.

 
Locate the TPMS Reset Button
 

• • Find the TPMS reset button, which is typically located beneath the steering wheel or in the glove box area. Consult your owner's manual if you're having trouble locating it.

 
Press and Hold the Reset Button
 

• • Press and hold the TPMS reset button until the TPMS light flashes slowly three times. Release the button after the third flash.

 
Drive the Vehicle
 

• • Start your Camry and drive for about 10–30 minutes at a speed of 25 mph or more, allowing the system to complete the reset process. This helps the vehicle to recalibrate and recognize the current tire pressures.

 
Verify the Reset Process
 

• • After driving, check that the TPMS warning light is off. If it remains on, repeat the process, ensuring all tire pressures are correct. If the problem persists, there may be an issue with one of the TPMS sensors, or it might require professional service.
