This guide assumes your tires are manually verified to be inflated to Honda’s recommended PSI (check driver’s door jamb sticker).
Contents
Most Likely Causes (Ranked)
- TPMS needs recalibration/reset (40% probability)
- Faulty TPMS sensor battery (30% probability, lifespan: 5-10 years)
- Signal interference (15% probability)
- System glitch requiring reboot (10% probability)
- Wiring/ABS module issue (5% probability)
Verify Tire Pressure Correctly
- Check all tires, including the spare (if equipped with TPMS).
- Measure pressure when tires are cold (not driven for 3+ hours).
- Compare to Honda’s recommended PSI (e.g., typically 32-36 PSI for most models).
Warning: If the ABS light is also on, stop driving and seek professional diagnosis immediately.
Reset the TPMS System
Model-Specific Reset Methods:
- 2018+ Accord/Civic/CR-V: Use touchscreen (Vehicle Settings > TPMS Calibration > Initialize).
- 2015-2020 Models: Hold TPMS button (left of steering wheel) until light blinks twice.
- Older Models: May require driving at 50+ mph for 10 minutes to auto-relearn.
After reset, drive for 15-20 minutes to allow the system to update.
Diagnose Sensor Issues
- Symptoms of a dead sensor: One tire’s pressure never updates, and intermittent warnings.
- Try this test:
- Deflate one tire to 25 PSI (temporarily).
- If the TPMS light doesn’t trigger within 5 minutes of driving, that sensor is faulty.
- Reinflate the tire immediately after the test.
Check for Interference
- Remove any aftermarket electronics (dashcams, GPS) near the dashboard.
- Avoid placing phones/keys near the center console while driving.
- If using aftermarket wheels, ensure they’re TPMS-compatible.
Professional Diagnostics (When DIY Fails)
- The cost estimate is $50-$150 for diagnosis at an independent shop and $100-$250 at a dealership.
- Technicians will:
- Scan for DTCs (e.g., code C1710 = right-front sensor fault).
- Test sensor RF signals with a TPMS tool.
- Check wiring harnesses near each wheel well.
Cost-Saving Tips
- Sensor replacement: $50-$150 per sensor (aftermarket) vs. $200-$350 (OEM).
- Independent shops often charge 30% less than dealerships for labor.
- Consider purchasing a TPMS reset tool ($50-$100) if you change tires seasonally.
Safety Note: Driving with a TPMS light is generally safe if pressures are confirmed correct; disable alerts at your own risk. Never ignore low-pressure warnings.
