⚠️ Safety Warnings

Important safety information - read before proceeding

•Allow tires to cool before checking or adjusting pressure to avoid inaccurate readings.
•Ensure the vehicle is secured on a flat surface when working on tires.

Symptoms

•Tire pressure warning light remains illuminated on the dashboard
•Possible decrease in fuel efficiency
•Uneven tire wear
•Vehicle handling issues (e.g., pulling to one side)
•Potential for a flat tire if pressure is significantly low

Diagnostic Steps

1
Check tire pressures using a reliable tire pressure gauge to ensure they meet manufacturer specifications.
2
Inspect each tire visually for any signs of damage, such as punctures or sidewall bulges.
3
Use an OBD-II scanner to check for any error codes related to the TPMS.
4
Inspect the TPMS sensors on each wheel for corrosion or damage.
5
Perform a reset of the TPMS system according to the vehicle's manual.
6
Monitor tire pressures after resetting to see if the warning light reappears.

Solution

Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, and tire inflator.
Ensure the vehicle is parked on a level surface and the tires are cold to get accurate pressure readings.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Inflate any tire that is below the recommended pressure (usually found on the driver’s side door jamb).
4. Replace valve caps after checking.

3. Inspect TPMS Sensors

Sub-steps:
1. Remove the wheel from the affected tire (if necessary).
2. Inspect the TPMS sensor located inside the tire for damage or corrosion.
3. If damaged, replace the TPMS sensor with a new one.
4. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications.

4. Reset the TPMS

Sub-steps:
1. With the vehicle in the "On" position (engine can be running or off), press the TPMS reset button (usually located under the steering wheel).
2. Hold the button until the TPMS light blinks three times, then release.
3. Drive the vehicle for a short distance (about 10 minutes) to allow the system to recalibrate.
