The importance of this device cannot be overemphasized since the status of your tires is not something to be trifled with, for your safety as much as for others too. But can the TPMS be disabled deliberately for some reasons without any risks?
The United State Department of Transportation, for instance, has mandated that effective from 2008, all vehicles manufactured must have the TPMS installed in them. Furthermore, even though you cannot disable the pressure monitoring device in any General Motors(GM) vehicle, you can reset it after you have checked your tires and inflated them properly.
In essence, you are not advised to disable a TPMS device. However, you can disable the system in some vehicles by removing the red wire from pin 2 and replacing it with the blue wire, pin 6. Doing this will completely disable it and its light will no longer shine on the instrument cluster of the dashboard. (Read Also: Is Uneven Tire Pressure Bad?Find Out)
How do you trick a tire pressure sensor?
Rather than pulling the pressure system apart, you can simply wiggle it around and stretch it out ever so slightly, until the light goes off eventually. This is the one way you can effectively trick the system, which is still not advised with good reasons.

Can you drive without a tire pressure sensor?
You can, but you really shouldn’t. Though you may really not get pulled over by the police for not having a tire pressure sensor, it is possible for you to fail a safety inspection if your state transport regulatory authority requires it. In cases where you wish to install a set of new wheels on your vehicle without the TPMS sensors, you may have to do that yourself, an effort that is not recommended at all.
How do I know if my tire pressure sensor is bad?
Causes of faulty TPMS sensors include a dead or failing car battery or when the TPMS module is not receiving any signal from one or more sensors due to antenna or wiring issues. Most vehicles have a tire pressure sensor relearn or retrain mode.
While in this mode, some vehicle sensors will send a signal to the module if the air is either removed or added to the tire. This pressure signal can then cause a horn chirp. Any sensor that does not produce this chirp is faulty.
How long does tire pressure sensors last?
The lithium-ion batteries provided in every tire pressure sensor can last anywhere between five to ten years. However, older versions of TPMS sensors last for only about five to six years.
The TPMS does not just broadcast a continuous signal arbitrarily, but broadcast signals only when the vehicle is in motion. Even at such times, the signal they broadcast is only intermittent in order to conserve the battery life.
Can you turn off a tire pressure sensor?
Yes, you can turn them off if you wish, though that is not advised, and to do so, you must first reprogram them for your vehicle too. The easiest way to disable them is by removing the red wire in pin 2 and replacing it with the blue one of pin 6. This will completely turn it off and it’s light on the dashboard will no longer illuminate as well. (Read Also: How Long Will Tires Last With Cords Showing?)
How accurate is the tire pressure monitoring system?
The direct TPMS measures the tire’s actual air pressure. Notably, such systems are usually accurate to within about 1 PSI. However, the current direct systems use a gauge mounted to the vehicle’s wheels or tire valve, which sends a signal to the vehicle’s computer system. So, the TPMS is as accurate as possible, just like most other devices such as fire alarms, burglary signals, smoke sensors and so on.Â
How do you fix a bad tire pressure sensor?
To fix a bad tire pressure sensor, first, apply a thread lock sealant to the outside surface of the threads of the recourse sensor saver approximately about 1/8 inch from the end that has no valve cap on it.
This should do the trick. However, if you only need to reset the system in order to get it going, start the car first, before turning the key to the ‘on’ position.
Then, press the TPMS reset button and hold it until its light blinks about three times before releasing it. Next, start the car and allow it to run for approximately 20 minutes in order to properly reset the sensor. The tire pressure reset button is commonly found beneath the vehicle’s steering wheel.
Frequently asked questions(FAQ)
Will TPMS light come on if the tires are overinflated?
Yes, they will. The tire pressure monitoring device is meant to notify you if anything is the matter with your tires in order to provide you with good enough notice early so that any accident can be averted before it occurs. Consequently, whatever concerns your tire pressure, you are bound to see the warning light coming on the dashboard.
How do you fix a tire pressure system without replacing it?
First, apply some lock sealant to the outside surface of the threads of the recourse sensor saver, approximately about 1/8 inch from the end which bears no valve entirely.
Can I use my old TPMS on my new wheels?
Indeed you can, but with careful observation to necessary details. As long as they are not damaged or have any malfunction, they are fully transferable. To do this properly, simply move your TPMS sensors to your new wheels from the old ones. Though you can easily do this switch-over, it is highly recommended that you order a new set of TPMS system hardware kit for your new wheels that include new seals suitable for your original TPMS sensors.
Do TPMSÂ need to be replaced?
Yes, they need to be under certain conditions. For example, you can replace them for reasons having to do with battery failure. Typically, TPMS sensor batteries have an average life span of between 5 to 10 years or after moving about 100 000 miles. Should their batteries die, it is necessary to replace the entire system.
Can I use wheels without TPMS?
Ideally, there should be no problem with running tires without a tire pressure sensor apart from, as you might have suspected, the warning light coming on and staying so.
However, when a tire is removed from the rim, there is no pressure, which implies that the TPMS has to be reset when the tire is either reinstalled or replaced with another.(Read Also: Can Tire Pressure Sensors Leak Air?Find Out Now)
How much does it cost for an alignment?

To put it simply, Sam’s Club does not offer any services that relate to the automobile oil change, as well as TPMS sensor replacement.
Why is my tire pressure light on even when my tires are fine?
In the majority of the cases, the tire pressure warning light can be mistakenly triggered by a tire that is about only 10 to 15 per cent low in air pressure. Also, cold or icy weather has the tendency to reduce the tire air pressure. However, by taking the car out for a short drive, it may heat up the tires thereby increasing the pressure. Consequent to these reasons, your tire pressure light may come on even when your tires have no issues.
How much does it cost to fix a tire pressure sensor?
All in all, complete TPMS sensor replacement costs are likely to be in the range of 230 and 750 dollars in most cases. Different from other auto repairs, the cost is mostly determined by the prices of the parts rather than the labour involved. TPMS sensors cost anything from 180 to 680 dollars mostly.
How can you tell when you have a bad tire pressure sensor?
Luckily, it is very easy to know when you have a faulty tire pressure sensor. Whenever the tire pressure sensor detects any problem, it will relay a signal to the car’s computer, which will, in turn, illuminate a light on the dash for your alert. This light is commonly bright yellow, and resembles an exclamation mark (!), within a ‘U’ shaped symbol.
Why do tire pressure sensors go bad?
In most cases where the TPMS are faulty, it is caused by tire pressure sensors that have become bad mostly due to expiration. The batteries inside the tire pressure sensors have a device life that usually ranges from 5 to 7 years. The tire pressure sensors are commonly known to fail as a result of corrosion on or inside the valve stem of the system.
Do I need to replace TPMS when replacing tires?
It is common for most auto shops to recommend that you service the TPMS after changing your vehicle tires or even the wheels by replacing any of the valve core, retaining nut, seal and cap on its valve system to make sure that it is functioning as it should at all times. Also, many direct systems can actually display the actual pressure in each of your vehicle tires.
What happens if you don’t replace TPMS sensors?
