Affected Component

Electrical

Estimated Time

1-3 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Ensure the vehicle is securely parked and on a level surface before beginning any work.

Symptoms

•TPMS warning light illuminated on the dashboard
•Possible uneven tire wear
•Decreased fuel efficiency
•Vehicle handling issues (e.g., pulling to one side)
•Tire pressure readings may be inaccurate or absent on the dashboard display

Diagnostic Steps

1
Inspect each tire visually for obvious signs of damage or under-inflation.
2
Check the tire pressure of all four tires using a tire pressure gauge.
3
Verify if the TPMS sensor is functioning by using an OBD-II scanner to check for any error codes related to the TPMS.
4
Reset the TPMS system through the vehicle’s settings or by following the reset procedure in the owner’s manual.
5
Check the vehicle's battery voltage and condition, as a weak battery may affect TPMS operation.
6
Inspect the TPMS sensors for corrosion or damage, especially if the vehicle has been in harsh conditions.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, torque wrench.

2. Inspect Tires

Sub-steps:
1. Use the tire pressure gauge to measure the pressure in each tire.
2. If a tire is significantly under-inflated (below manufacturer specifications), inflate it to the correct PSI as indicated on the driver’s door jamb.
3. Examine each tire for any visible punctures, cuts, or bulges.

3. Check and Replace TPMS Sensors (if needed)

Sub-steps:
1. If tire pressures are correct but the light remains on, use the OBD-II scanner to check for TPMS-related error codes.
2. If codes indicate a faulty sensor, proceed to replace the TPMS sensor.
3. Remove the tire from the wheel using a tire changing machine or manually with a jack and jack stands.
4. Remove the old TPMS sensor from the wheel and install the new sensor, ensuring proper torque specifications (usually around 5-7 ft-lbs).
5. Reinstall the tire onto the wheel and ensure it’s properly balanced.

4. Reset TPMS

Sub-steps:
1. Start the vehicle and navigate to the TPMS reset function in the settings menu, or follow the manual reset procedure (usually involves pressing the TPMS reset button).
2. Drive the vehicle for a short time (10-15 minutes) to allow the system to recalibrate.

5. Final Check

After resetting, monitor the TPMS light. If it remains illuminated, further diagnosis may be required.
