Symptoms
  • Warning light for low tire pressure illuminated on the dashboard.
  • Possible visual inspection may show one or more tires appear deflated.
  • Decreased handling or stability while driving.
  • Possible increase in road noise or vibration.
Diagnostic Steps

  1. Visual Inspection:

    • Check each tire for visible signs of deflation or damage (bulges, punctures, cracks).

  2. Check Tire Pressure:

    • Use a tire pressure gauge to measure the pressure in each tire.
    • Compare the readings to the recommended tire pressure listed on the driver’s door jamb or in the owner’s manual.

  3. Scan for Error Codes (if applicable):

    • Use an OBD-II scanner to check for any TPMS-related error codes.

  4. Inspect TPMS Sensors:

    • If the tire pressure is normal, the TPMS sensors may need inspection. Check for any damaged sensors or wiring.

  5. Check for Tire Leaks:

    • Perform a soapy water test on the tires. Spray a mixture of soap and water on the tire surface and valve stem. Look for bubbles indicating air leaks.
Repair Instructions

  1. Adjust Tire Pressure:

    • If any tires are below the recommended pressure, inflate them to the proper level using an air compressor.
    • Ensure to also check the spare tire, if applicable.

  2. Repair or Replace Tires:

    • If a tire is found to be damaged or leaking, either repair it (if it’s a minor puncture) or replace it with a new tire if the damage is extensive.
    • For tire repairs, follow these steps:
      1. Remove the wheel from the vehicle using a lug wrench.
      2. If repairing, apply a tire plug or patch kit as per manufacturer instructions.
      3. Reinstall the tire and torque the lug nuts to the manufacturer's specifications.

  3. TPMS Sensor Replacement (if needed):

    • If diagnosed that the TPMS sensor is faulty:
      1. Remove the tire from the wheel.
      2. Unscrew the old TPMS sensor and install the new sensor.
      3. Reassemble the wheel and tire back onto the vehicle.

  4. Reset TPMS Light:

    • After correcting the tire pressure or replacing any parts, reset the TPMS light by following these steps:
      1. Turn the ignition to the "ON" position (do not start the engine).
      2. Press and hold the TPMS reset button (usually located under the steering column) until the TPMS light blinks three times, then release it.
      3. Start the vehicle and check if the warning light has turned off.
Tools Required
  • Tire pressure gauge
  • OBD-II scanner
  • Air compressor
  • Soapy water solution (for leak detection)
  • Tire plug or patch kit (if repairing)
  • Lug wrench
  • Torque wrench (for lug nuts)
  • Replacement TPMS sensors (if needed)
Estimated Time for Repair
  • Adjusting tire pressures: 10-15 minutes.
  • Tire repair: 30 minutes to 1 hour (depending on the severity).
  • TPMS sensor replacement: 1-2 hours (including tire dismount and remount).
Safety Warnings
  • Ensure the vehicle is on a flat surface and securely supported when working on tires.
  • Follow proper safety procedures when using an air compressor and handling tools.
