Solution

Certainly! Here’s a detailed guide on how to diagnose and fix the Tire Pressure Monitoring System (TPMS) error in your 2018 Toyota Camry (XV70).

Tools Required

Tire pressure gauge
OBD-II scanner
TPMS reset tool (optional, but may be helpful)
Air compressor (if tire pressures need adjustment)
Basic hand tools (screwdrivers, wrenches)
Tire patch kit (if a tire puncture is found)

Repair Instructions

Step 1: Adjust Tire Pressures

Inflate or deflate the tires to match the recommended pressures. This may require using an air compressor or releasing air.

Step 2: Replace a Faulty TPMS Sensor

If tire pressures are correct and the warning light persists, one or more TPMS sensors may be faulty.
Remove the tire from the rim using a tire machine or manual tire removal tools.
Inspect the TPMS sensor for damage or corrosion.
If necessary, replace the sensor:
- Use a 7mm socket to remove the valve nut securing the TPMS sensor.
- Replace the old sensor with a new one, ensuring proper alignment.
- Reinstall the valve nut and torque it to specifications (typically around 4.5 ft-lbs).

Step 3: Reprogram the TPMS (if applicable)

After replacing a sensor, it may need to be reprogrammed to the vehicle’s system. This can typically be done with a TPMS reset tool or through the OBD-II scanner.
Follow the specific instructions for your tool/model to program the new sensor.

Step 4: Recheck the System

After adjustments or repairs, reset the TPMS again if necessary.
Start the vehicle and check if the TPMS warning light has turned off.

Conclusion

If after following these steps the TPMS warning light remains illuminated or new error codes appear, further investigation may be necessary. This may involve checking the wiring and connectors related to the TPMS or consulting with a professional technician for more advanced diagnostics.
