Will a Low Tire Pressure Light Fail Inspection?
Can a TPMS Light Cause Inspection Failure?
It depends on your state’s inspection requirements. In some states, a Tire Pressure Monitoring System (TPMS) warning light can cause a failed safety inspection, while in others, it does not affect passing or failing the test.
State-by-State Rules for TPMS Light During Inspection
States That May Fail a Vehicle for a TPMS Light
- New York
- Texas
- Virginia
- Massachusetts
- Pennsylvania (for some inspections)
In other states, the TPMS light is not checked as part of the inspection process.
Why a Low Tire Pressure Light Might Cause Failure
- Indicates Low Tire Pressure – Low-pressure tires can affect handling and braking.
- TPMS Malfunction – Some states require all dashboard warning lights to be off.
- Tire Safety Concerns – Underinflated tires increase the risk of blowouts or poor fuel efficiency.
How to Fix a Low Tire Pressure Light Before Inspection
- Check and Inflate Tires – Use a tire pressure gauge to ensure all tires are at the manufacturer-recommended PSI.
- Reset the TPMS System – Some vehicles require a manual reset after adjusting pressure.
- Drive for a Few Miles – The system may take a few minutes to recognize the correct pressure.
- Check for Faulty TPMS Sensors – If the light stays on, a sensor may need to be replaced.
- Replace Dead TPMS Sensor Batteries – Sensors inside the wheels use batteries that last 5–10 years.
Final Thoughts
A low tire pressure light may or may not cause an inspection failure, depending on your state’s requirements. To avoid issues, inflate your tires properly, reset the TPMS, and check for faulty sensors before going for an inspection.
FAQs
1. Can I pass an inspection with the TPMS light on?
In some states, yes (especially emissions-only tests). In others, no, especially if a full safety check is required.
2. How do I reset my TPMS light before inspection?
- Inflate all tires to the recommended PSI.
- Drive for a few miles to let the system update.
- Some cars have a TPMS reset button inside the glove box or dashboard.
3. What if my TPMS sensors are bad?
If a sensor is malfunctioning, it may need to be replaced, which costs $50–$150 per sensor.
4. Can I disable my TPMS light to pass inspection?
No, removing or tampering with the TPMS system is illegal in some states and may cause failure.
5. How often should I check my tire pressure?
At least once a month or before long trips to ensure safe driving conditions.
