Common Tire Pressure Monitoring System (TPMS) Faults in the 2019 Toyota Camry
Common Causes of TPMS Faults
  1. Low Tire Pressure: One or more tires are under-inflated.
  2. Faulty TPMS Sensors: Sensors may become defective or damaged.
  3. Dead Sensor Batteries: TPMS sensors have batteries that can wear out over time.
  4. Signal Interference: Electronic interference may disrupt communication between sensors and the ECU.
  5. Improper Tire Installation: Incorrect installation of tires or sensors can lead to faults.
  6. Damaged Wiring: Wiring issues can prevent signals from reaching the ECU.
  7. TPMS Module Malfunction: The main control module for the TPMS may be faulty.
Step 1: Gather Tools
  • Tire pressure gauge
  • OBD-II scanner with TPMS capabilities
  • Tire inflator
  • Basic hand tools (wrench set, screwdriver)
  • Multimeter (for wiring issues)
  • Replacement TPMS sensors (if necessary)
Step 2: Check Tire Pressures
  1. Remove Valve Caps: Carefully remove the valve caps from each tire.
  2. Measure Tire Pressure: Use a tire pressure gauge to check the pressure in all four tires.
  3. Compare Readings: Compare the readings with the specifications found on the driver’s side door jamb.
  4. Inflate Tires as Necessary: Inflate any tire that is below the recommended pressure.
Step 3: Scan for Codes
  1. Connect OBD-II Scanner: Plug the scanner into the OBD-II port under the dashboard.
  2. Read TPMS Codes: Access the TPMS module and check for any stored fault codes.
  3. Document Codes: Write down any codes that are displayed for further analysis.
Step 4: Inspect TPMS Sensors
  1. Visual Inspection: Examine each tire for visible damage to the valve stem and sensor.
  2. Use a TPMS Tool: If available, use a TPMS tool to activate each sensor and check for response.
  3. Check Battery Levels: If the tool indicates a failure, consider the possibility of a dead battery within the sensor.
Step 5: Check Wiring and Connections
  1. Inspect Wiring: Check the wiring harness connecting to the TPMS module for any damage or corrosion.
  2. Use a Multimeter: Test continuity in the wiring harness to ensure there are no breaks.
Step 6: Reset TPMS
  1. Follow Reset Procedure: If all tires are properly inflated and sensors are functional, reset the TPMS.
    • Turn the ignition to the "On" position without starting the engine.
    • Locate the TPMS reset button (usually under the dashboard or near the steering column).
    • Press and hold the button until the TPMS light blinks three times, then release.
    • Drive the vehicle for a few minutes to allow the system to recalibrate.
Repair Instructions
Replacing Faulty TPMS Sensors
  1. Remove Tires: Use a tire changer or jack to lift the vehicle and remove the wheel with the faulty sensor.
  2. Unseat the Tire: Use tire levers to break the bead and unseat the tire from the rim.
  3. Remove Old Sensor: Unscrew the valve stem nut and remove the sensor from the tire.
  4. Install New Sensor: Place the new sensor in the valve stem hole and secure it with the nut.
  5. Re-seat the Tire: Carefully re-seat the tire onto the rim and inflate it to the correct pressure.
  6. Reinstall Tire: Mount the tire back onto the vehicle and torque the lug nuts to the manufacturer’s specifications.
Replacing TPMS Module (if necessary)
  1. Locate TPMS Module: Refer to the service manual to find the TPMS control module’s location (usually under the dashboard).
  2. Disconnect Battery: Disconnect the negative terminal of the battery to ensure safety.
  3. Remove Module: Take out the screws or bolts securing the module and disconnect the wiring harness.
  4. Install New Module: Connect the new TPMS module and secure it in place.
  5. Reconnect Battery: Reconnect the negative battery terminal.
  6. Recalibrate System: Follow the TPMS reset procedure to ensure proper operation.
Final Verification
  1. Test Drive: After repairs, take the vehicle for a test drive to confirm that the TPMS light turns off.
  2. Re-check Tire Pressures: After driving, re-check the tire pressures for consistency with the TPMS readings.

These steps should help you diagnose and repair common TPMS faults in a 2019 Toyota Camry. Always refer to the specific service manual for detailed specifications and procedures as they can vary by model and trim level.
