Affected Component

Electrical

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the vehicle to cool before working on the tires.

Symptoms

•TPMS warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed
•Warning message related to tire pressure on the information display
•Possible loss of tire pressure leading to handling issues

Diagnostic Steps

1
Scan the vehicle's onboard diagnostics using an OBD-II scanner to retrieve any TPMS-related error codes.
2
Visually inspect all tire pressures using a reliable tire pressure gauge to ensure they are within manufacturer specifications.
3
Check the condition of the tire pressure sensors for any visible damage or corrosion.
4
Verify the battery status of the tire pressure sensors, especially if the vehicle has a low battery warning.
5
Reset the TPMS system through the vehicle's settings or using a TPMS reset tool after checking tire pressures.

Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, TPMS reset tool, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery for safety if working on electronic components.

2. Tire Pressure Check

Using a tire pressure gauge, measure the pressure of each tire.
Inflate or deflate the tires as necessary to meet the recommended pressure specifications found in the owner’s manual or on the driver's side door jamb.

3. Sensor Inspection

Remove each tire using a jack and jack stands.
Inspect the tire pressure sensors located within the tire valve stems.
Look for any signs of damage such as cracks or corrosion on the sensor body.
If damaged, proceed to replace the sensor (see next step).

4. Sensor Replacement (if necessary)

For each damaged sensor, remove the tire from the rim using a tire machine.
Replace the old tire pressure sensor with a new one, ensuring it’s the correct part for the Toyota Camry.
Reinstall the tire onto the rim and balance as necessary.

5. TPMS Reset

After addressing any issues, use the TPMS reset tool or follow the vehicle's manual to reset the TPMS system. This usually involves turning the ignition on without starting the engine and pressing the TPMS reset button until the TPMS light blinks three times.
Confirm the system has reset by checking for the TPMS light status.
