Affected Component

Suspension

Estimated Time

1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported if working underneath it.
•Allow the tires to cool before measuring pressure to avoid inaccurate readings due to heat expansion.

Symptoms

•Tire pressure warning light illuminated on the dashboard
•Possible fluctuation in vehicle handling or ride comfort
•Audible alerts when the vehicle is started or driven
•Visual indication of specific tire with low pressure (if equipped)
•Possible decrease in fuel efficiency

Diagnostic Steps

1
Verify the tire pressures using a tire pressure gauge, checking against the recommended PSI listed on the driver's door jamb.
2
Inspect each tire for visible damage, punctures, or foreign objects that may cause air loss.
3
Check the condition and functionality of the TPMS sensors in each wheel.
4
Scan the vehicle’s computer using an OBD-II scanner to check for TPMS-related error codes.
5
Reset the TPMS system through the vehicle’s settings or using the reset button (if applicable).

Solution

Solution

1. Preparation

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

2. Check Tire Pressures

Remove valve caps from each tire.
Use the tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to match the recommended PSI (found on the driver’s door jamb).

3. Inspect Tires

Visually inspect each tire for cuts, punctures, or signs of excessive wear.
If damage is found, consider replacing the tire or having it repaired by a professional.

4. Inspect and Test TPMS Sensors

Remove the tire from the wheel if necessary to access the TPMS sensor.
Check the sensor battery life and functionality; replace if necessary.
Reinstall the tire and ensure it is properly seated on the rim.

5. Reset TPMS

Locate the TPMS reset button (usually found under the steering wheel or in the glove compartment).
Turn the ignition to the "ON" position (do not start the engine).
Press and hold the TPMS reset button until the TPMS light blinks three times, then release.
Start the engine and wait for a few minutes for the system to recalibrate.
