The Tire Pressure Monitoring System (TPMS) in the Honda Accord serves as a safeguard, alerting you to any irregularities in tire pressure. Issues with the TPMS can stem from low tire pressure, sensor battery life, or system calibration needs. This guide will help you identify common issues and ways to restore your TPMS to optimal functioning.
1. Key Causes of Honda Accord Tire Pressure Sensor Fault
For Honda Accords, TPMS faults are typically due to:
- Low Tire Pressure: Cold temperatures, gradual air loss, or small punctures can drop tire pressure below recommended levels.
- Sensor Battery Depletion: The lifespan of TPMS sensors is generally between 5-10 years, after which they may need replacement.
- Sensor Damage: Potholes, curb impacts, or mishandling during tire changes can damage the sensors.
- TPMS Recalibration Needs: After any tire rotation, replacement, or realignment, Honda recommends recalibrating the TPMS.
2. Troubleshooting Honda Accord Tire Pressure Sensor Faults
Step 1: Check and Adjust Tire Pressure
- Using a tire pressure gauge, measure the pressure in each tire.
- Match the pressure to the recommended level (found in your Accord’s manual or on the door sticker).
- If the light stays on, try driving for a few minutes to allow the system to recognize the adjustment.
Step 2: Reset the TPMS in Your Honda Accord
- Manual TPMS Reset: Many Accord models have a reset option within the settings.
- From your dashboard, navigate to TPMS Calibration and follow the prompts to reset the system.
- Drive for 20-30 minutes after resetting to allow the system to recalibrate.
Step 3: Inspect TPMS Sensors
- Persistent TPMS alerts might be due to a damaged or dead sensor. A tire service shop can test each sensor.
- During regular tire changes or rotations, ask the technician to inspect TPMS sensors for wear or damage.
Step 4: Visit a Professional for TPMS Diagnosis
- If issues persist, a professional scan can reveal specific sensor faults or battery issues.
- Certified auto shops can replace sensors as needed and reprogram them to sync with your Accord’s TPMS system.
3. Preventive Tips for Avoiding TPMS Warnings
- Monthly Tire Pressure Checks: Check your tire pressure regularly, especially with weather changes.
- Avoid Rough Impacts: Potholes and curbs can damage both tires and TPMS sensors.
- Prepare for Battery Replacement: After five years, TPMS sensors may start showing signs of low battery. Plan for proactive replacement to avoid unexpected alerts.
