Will Car Pass Inspection With TPMS Light On? (State By State)

When it comes to your tire air pressure, the TPMS has become one of the most useful systems a car can have because of how it automatically gives you real-time information regarding the air pressure in your tires.

So, when your tires are low in air pressure, the TPMS light on your dash board will turn on to warn you that you need to put some air in your tires. That said, if your TPMS lights are on when you have your car inspected, can you still pass the safety inspection?

Will your car pass with TPMS light on?

You can still pass your car safety inspection in the USA with the TPMS light is on provided that the tires actually have the right air pressure in certain states. That’s because the TPMS is only there to tell you that your tires are low on air pressure but the TPMS is not exactly always right especially when it is worn out or faulty. However, in most European countries like UK/Ireland, you will fail the test.

But less concentrate on the USA and while the safety inspectors do indeed check the TPMS to see if the light is on, they will not fail your safety inspection just because it is on. Remember here that the important part is that your tires have enough air pressure.

As such, it becomes immaterial that the TPMS light is on as long as your tires actually have the right air pressure regardless of what the TPMS is saying.

Will the car pass inspection with the TPMS light on?

One of the most amazing safety features that have been quite useful when it comes to many drivers is the TPMS.

That’s because the TPMS is capable of monitoring the tire pressure in your car and then provide a real-time feed of the readings to your dash board so that you yourself can see the status of your tire’s air pressure.

When the TPMS does indeed detect that one or more of the tires are beginning to lose air pressure, that is the time when the TPMS will inform you through a warning message or a warning light called the TPMS light.

So, when the TPMS light is on, that could mean that your tires may be losing air pressure and that it is time for you to put air into your tires again.

Of course, this can be useful because of the very fact that you no longer have to manually check your tires for air as the system automatically does it for you.

And another thing you need to consider here is the fact that knowing how much air pressure is in your tires from a real-time standpoint can be a lifesaver especially when you consider the dangers involved with having tires with low air pressure.

You don’t want to lose control over your car while driving at high speeds on the freeway.

That said, if you have your car undergo inspection and your TPMS light is on, what happens? Will your car pass the safety inspection even if the TPMS light is on? Well, the answer to that question depends on certain factors.

For starters, the safety inspector will indeed check the TPMS to see if the light is on. If it is on, that is a cue for the inspector to check the air pressure of your tires. So, in that regard, the tires are still more important in the sense that, as long as the tires have the right air pressure, your car will pass the safety inspection regardless of what the TPMS says.

The reason for this is due to the fact that the TPMS isn’t always accurate in telling whether or not the air pressure in your tires is enough.

That’s because the TPMS is still bound to fail from time to time especially if it has become worn out or if it is faulty. 

Of course, there is also the fact that the tires are still the more important pieces here. There was a time when people didn’t rely on the TPMS but were still able to make sure their tires had enough air in them.

As such, as long as you made sure to keep the right air pressure in your car, you are more likely safe to go regardless of what the TPMS light is saying.

So, even if your TPMS made a mistake by turning on the warning light even, you can still pass the safety inspection as long as the tires have enough air in them. But this is still subject to another factor.

Do you need to fix the TPMS light before the inspection?

Now that you know that you can still pass your safety inspection even if your TPSM light is on, you still need to know one more consideration, and that is the TPMS itself.

So, if your TPMS light is on due to a faulty system or to damaged sensors and not due to a simple mistake, this can still be a cause for not passing your car for safety.

The reason for that is due to the fact that there are some states that will require you to make sure that you have a working and functional TPMS before they pass your car for safety.

As such, if your TPMS light is on due to a damaged TPMS, then there is a chance that you still won’t pass the safety inspection even if your tires have the right air pressure.

As of this writing, the states that require you to have a functional TPMS to pass safety inspection are Hawaii, Rhode Island, Vermont, and West Virginia. If you live in those states, you need to make sure that your TPMS is working properly regardless of whether or not your tires have the right air pressure.

Then there are also states such as New York that will still inspect your TPMS to see if it is working. However, the TPMS is not a factor for failing your car’s safety inspection even if the TPMS is not working. Still, you would have to make sure that your tires have the right air pressure for you to pass.

How do you turn off the TPMS light before the inspection?

The only way for you to turn off the TPMS light before inspection is to reset the TPMS.

Resetting the TPMS can be different from car to car but you usually have to press the reset button and hold it until it blinks.

From there, all you need to do is to let your car run for about 20 minutes for the sensors to detect the air pressure in the tires.

Resetting the TPMS light should work before inspection if and only if your tires have enough air. However, if you tried resetting the TPMS even if your tires don’t have any air in them, then the TPMS light will still turn on later.

This is why it is very important to make sure that your tires have the right air pressure.
