The TPMS (Tire Pressure Monitoring System) light typically does not directly cause an emissions test failure , as emissions tests focus on pollutants from the engine/exhaust (e.g., CO, NOx, hydrocarbons) and the functionality of emissions control systems (e.g., catalytic converter, OBD-II diagnostics).
Will TPMS Warning Fail Emissions Test?
Here are some indirect considerations about Will Tpms Light Fail Emissions:
1. TPMS and Emissions Testing
- The TPMS light itself (e.g., a malfunctioning sensor or low tire pressure) is not part of emissions testing criteria in most jurisdictions. Emissions tests primarily check:
- Exhaust gas composition (via tailpipe sniffer or OBD-II scan).
- Readiness monitors (e.g., catalytic converter, oxygen sensors).
- TPMS issues are unrelated to emissions control systems, so they generally won’t cause a test failure.
2. Indirect Effects
- Low Tire Pressure : If the TPMS light is on due to underinflated tires, it could theoretically reduce fuel efficiency and increase emissions over time. However, emissions tests measure instantaneous tailpipe output , not long-term fuel economy, so this would not directly cause a failure.
- OBD-II Readiness : If the TPMS malfunction triggers a broader OBD-II system fault (unlikely), it might affect readiness monitors. But TPMS faults are usually isolated and do not impact emissions-related systems.
3. Safety vs. Emissions Inspections
- In states/countries with combined safety and emissions inspections (e.g., New York, California), a malfunctioning TPMS light could result in a safety inspection failure , even if emissions are compliant. For example:
- New York State : TPMS functionality is part of the safety inspection for vehicles model year 2008 and newer. A failed TPMS could result in a rejected inspection sticker, even if emissions pass.
4. What to Do
- Check Local Regulations : Verify if your jurisdiction includes TPMS in its inspection criteria (safety or emissions).
- Address TPMS Issues : Fixing the TPMS (e.g., correcting tire pressure, replacing faulty sensors) ensures compliance with safety standards and avoids potential complications during inspections.

Is It Ok to Drive Without Tpms Sensors?
No, it is not OK to drive without TPMS sensors. Tire Pressure Monitoring Systems (TPMS) are designed to alert drivers when tire pressure falls below a certain threshold and can help prevent accidents caused by under-inflated tires.
Without this system in place, you may find yourself driving on tires that are dangerously low on air pressure and could suffer from decreased traction or even a blowout as a result.
This could lead to dangerous situations such as skidding or loss of control of your vehicle which puts both yourself and others around you at risk.
The cost associated with replacing or fixing an under-inflated tire is something that could have been avoided had the TPMS sensor been present in the first place.
Therefore, for your safety and for those around you, it is recommended that all vehicles be equipped with functioning TPMS sensors before hitting the road!
How Serious is a Tpms Light?
A TPMS (Tire Pressure Monitoring System) light is a warning signal that can be triggered when the pressure in one or more of your tires falls below the recommended level.
It’s important to take this warning seriously, as improperly inflated tires not only reduce fuel efficiency but also increase the risk of an accident due to reduced handling and braking ability.
Even if you don’t notice any difference in ride quality, it’s best to take immediate action when your TPMS light comes on.
Check all four tire pressures with a reliable gauge, and then use compressed air or a portable compressor to bring them back up to their recommended levels before continuing your journey.
If you’re unable to do this, have your vehicle towed somewhere safe where the tire pressure can be checked and adjusted by a professional technician.
Ignoring this warning could put yourself and other road users at increased risk – so make sure you act quickly if your TPMS light illuminates!
Will Tpms Throw a Code?
TPMS, or Tire Pressure Monitoring System, is an important safety feature found on many modern cars. The system is designed to alert drivers when their tire pressures are low, helping them avoid dangerous situations caused by flat tires or underinflated tires. But does TPMS throw a code?
The answer depends on the type of TPMS system your car has installed. On some vehicles, TPMS will not throw a code in the event of a low tire pressure warning – it simply triggers an indicator light on the dashboard that alerts you to check your tires manually.
Other systems may be more advanced and actually trigger a fault code if there’s an issue with the system itself or one of its sensors; this type of fault code must be diagnosed and cleared by a technician using special scan tools.
In either case, though, it’s important to monitor your tire pressures regularly so that you can stay safe while driving—even if your vehicle isn’t equipped with TPMS at all!
Will Low Tire TPMS Warning Light Fail Car Inspection?
Can You Pass Emissions With Tire Pressure Light on in Arizona
In Arizona, passing emissions with a tire pressure light on is allowed as long as the vehicle passes all other tests.
However, if the tire pressure light stays illuminated after being checked and corrected by a qualified technician, it may be an indicator of another issue that should be addressed to ensure safe driving conditions.
If your vehicle fails any other aspect of the emissions testing process, including but not limited to exhaust system issues or malfunctioning catalytic converters, you will not be able to pass inspection until these issues are resolved.
Conclusion
Tire pressure monitoring systems (TPMS) can play an important role in helping to keep your car running safely and efficiently. It is important to be aware of the fact that TPMS lights may fail emissions if they are not functioning properly.
Therefore, it is recommended that you regularly check your TPMS light whenever possible and pay attention to any warning signs or indicators that could indicate a problem with the system.
Doing so will help ensure that your car passes emissions tests and remains safe on the road.
