How do I resolve the recurring TPMS warning light on my Corolla E210?

To resolve a recurring Tire Pressure Monitoring System (TPMS) warning light on your Toyota Corolla E210 (2019-2024), follow these detailed steps:

Symptoms:

• TPMS warning light illuminated on the dashboard.
• Possible message indicating low tire pressure or TPMS malfunction.

Diagnostic Steps:

1. Check Tire Pressure:

   • Tools Required: Tire pressure gauge.
   • Steps:
     1. Park the vehicle on a level surface and ensure the tires are cool.
     2. Refer to the driver’s side door jamb for the recommended tire pressure (usually around 32-35 psi for most models).
     3. Use the tire pressure gauge to measure the pressure of each tire, including the spare if applicable.
     4. Inflate any tires that are below the recommended pressure using an air compressor.

2. Inspect for Tire Damage:

   • Steps:
     1. Visually inspect each tire for signs of damage such as punctures, cuts, or sidewall bulges.
     2. If any damage is found, replace the tire as needed.

3. Reset the TPMS:

   • Steps:
     1. Turn the ignition to the "ON" position without starting the engine.
     2. Locate the TPMS reset button, typically found under the steering wheel or in the glove box.
     3. Press and hold the reset button until the TPMS light blinks slowly three times.
     4. Start the car and let it run for a few minutes. Drive at a speed above 25 mph for at least 10 minutes to allow the system to recalibrate.

4. Scan for TPMS Fault Codes:

   • Tools Required: OBD-II scanner with TPMS capabilities.
   • Steps:
     1. Connect the OBD-II scanner to the diagnostic port under the dashboard.
     2. Scan for any TPMS-related error codes.
     3. If codes are present, refer to the scanner’s manual or a repair manual for specific troubleshooting steps.

5. Check TPMS Sensor Batteries:

   • Steps:
     1. If the TPMS warning light persists, the sensor batteries may be depleted.
     2. TPMS sensors typically have a lifespan of 5-10 years. If your vehicle is within this range, consider replacing the sensors.

Parts/Components That May Need Replacement:

• TPMS sensors (if batteries are depleted or sensors are faulty).
• Tires (if damaged).

Estimated Time for Repair/Maintenance:

• Checking and adjusting tire pressure: 15-30 minutes.
• Resetting TPMS: 5-10 minutes.
• Scanning for codes and further diagnostics: 30-60 minutes.
• Replacing TPMS sensors: 1-2 hours.

Safety Warnings:

• Ensure the vehicle is parked on a stable, flat surface before performing any checks or repairs.
• Use caution when inflating tires to avoid over-inflation, which can lead to tire damage or failure.

By following these steps, you should be able to resolve the TPMS warning light issue on your Toyota Corolla E210. If the problem persists after performing these steps, it may be necessary to consult a professional technician for further diagnosis.
