⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is secured on jack stands before working on it.
•Wear safety glasses when working with tires and sensors.

Symptoms

•TPMS warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed
•Tire pressure light blinking intermittently
•Possible loss of tire pressure
•Warning message on the vehicle's display

Diagnostic Steps

1
Check tire pressures using a reliable tire pressure gauge to ensure they are within manufacturer specifications.
2
Scan the vehicle's onboard diagnostics (OBD-II) system for any stored error codes related to the TPMS.
3
Inspect each tire for visible damage or leaks that may cause pressure loss.
4
Verify that the TPMS sensors are installed correctly on each wheel.
5
Check the vehicle's battery voltage to ensure it is sufficient for TPMS operation.
6
Reset the TPMS system via the vehicle’s settings or using a TPMS reset tool if applicable.

Solution

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check and Inflate Tires

Use a tire pressure gauge to measure the pressure of all four tires.
Inflate or deflate tires to match the recommended pressure specified on the driver’s door jamb sticker.

3. Replace TPMS Sensors (if required)

Tools Required: Tire iron, jack, TPMS sensor tool, torque wrench.
Sub-steps:
1. Loosen the lug nuts of the wheel where the TPMS sensor needs replacement.
2. Jack up the vehicle and safely secure it on jack stands.
3. Remove the wheel and tire assembly.
4. Use a TPMS sensor tool to remove the faulty sensor from the valve stem.
5. Install the new TPMS sensor onto the valve stem and tighten to manufacturer specifications (typically 4-5 ft-lbs torque).
6. Reassemble the tire and wheel onto the vehicle.
7. Torque the lug nuts to the manufacturer’s specified value (usually 76-86 ft-lbs).

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the "On" position without starting the engine.
2. Press the TPMS reset button (located under the steering wheel or in the glove compartment) until the TPMS light blinks three times.
3. Start the engine and drive the vehicle for about 10 minutes to allow the system to recalibrate.
