Important safety information - read before proceeding

•Ensure the vehicle is securely supported on jack stands before removing tires.
•Always allow tires to cool before measuring tire pressure for accurate readings.

Symptoms

•Tire pressure warning light remains on
•Inconsistent tire pressure readings
•Possible rough ride or decreased handling
•Low tire pressure in one or more tires
•Increased fuel consumption

Diagnostic Steps

1
Check the tire pressures of all four tires using a tire pressure gauge.
2
Inspect the tires for visible damage or signs of a puncture.
3
Use an OBD-II scanner to check for any related fault codes in the tire pressure monitoring system (TPMS).
4
Inspect the TPMS sensors for battery life and proper installation.
5
Reset the TPMS system following the manufacturer's procedure.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, OBD-II scanner, and a jack.
Ensure that the vehicle is parked on a level surface and the engine is off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from all tire valves.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Compare readings with the recommended pressures found on the driver's door jamb.
4. Inflate any under-inflated tires to the recommended PSI.
5. Replace valve caps securely.

3. Inspect TPMS Sensors

Sub-steps:
1. If tire pressure is correct, remove the tires one at a time to access the TPMS sensors.
2. Visually inspect the sensors for damage or corrosion.
3. Replace any faulty sensors with new ones, ensuring they are properly secured.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the ON position without starting the engine.
2. Locate the TPMS reset button (usually under the steering wheel or in the glove box).
3. Press and hold the reset button until the TPMS light blinks three times, then release.
4. Start the engine and allow the system to recalibrate.
