Jeep Wrangler Tire Pressure Sensor Disable

Know the correct way to handle the problems with your TPMS 

It is common to find Jeep owners reporting problems with their TPMS. These problems usually arise right when you switch to new off-road tires or when you start navigating the roadless path more often. While figuring out the problem with their TPMS systems, many users suggest turning it off completely. While this idea seems tempting, it is also illegal. The correct way to address the problems with your TPMS should involve repair, replacements, or resetting, not a disablement. Read all that you need to know about Jeep wrangler tire pressure sensor disable.

It is not okay to disable your Jeep’s TPMS 

According to the National Highway Traffic Safety Administration’s Motor Vehicle Safety Act 49 USC 30122(b), the disabling of your car’s TPMS system is illegal. Under the ‘make inoperative’ provision of this act, any manufacturer, distributor, dealer, or motor vehicle repair business cannot make the TPMS inoperative intentionally. 

No doubt this would save you a lot of money, but it could also land you in trouble. The TPMS can be brought back into working order with the quality repair without indulging in its removal. Note that a bad TPMS sensor can definitely be replaced with a standard rubber valve stem if the TPMS failure occurred before the Jeep was brought in. however, an intentional disabling of this system would be a violation of the ‘make inoperative’ provision. 

This would not only create problems for you, but it would also bring consequences for the mechanic who indulges in this activity. It isn’t okay even if the TPMS system is disabled during the correction of some other issue or service. It is also not acceptable to install another set of wheels or tires without the required TPMS sensors. This would create problems for both the mechanic and the Jeep owner. New TPMS sensors must be sold along with new rims and they should be properly programmed into the vehicle’s TPMS system. 

To stay safe, one must maintain absolute precaution during the repair of a vehicle’s tires. Note that all tire repairs should only extend up to the tread area. The outside shoulder and the sidewall should not be included. The removal of the tire must be undertaken through the rim/wheel assembly and the subsequent repairs must not overlap. A puncture injury can be adequately filled with a rubber plug or stem that is sealed with the help of an inner liner. 

Jeep Wrangler Tire Pressure Sensor Disable

TPMS problems are commonly encountered with Jeeps used for off-roading 

Experts recommend always air down your tires well before hitting an unpaved path. They should ideally be taken down to 15-20 PSI for rough terrains. While this is a proper mechanism, it could still set off the TPMS light. Most Jeep users have learned to ignore this problem, but it can surely become annoying. This light doesn’t go off until the tire pressure is raised again. 

Although, a quality custom tuner can be used to adequately monitor the tire pressure and adjust the threshold of the warning. This issue could also arise for those who have purchased and installed bigger aftermarket tires. Improperly programmed tires could also play with the TPMS sensors. However, this problem can be adequately dealt with at a repair shop. 

Many off-road tire packages now come with inclusive TPMS sensors so you don’t have to purchase them separately. You must note how difficult it is to replace the TPMS sensors by yourself. Considering that you’ll need to completely deflate your tire and then use a tire remover to separate it from the wheel. 

There could be several reasons behind your faulty TPMS system

Several background problems could interfere with the proper working of your TPMS sensors. You must figure out the exact issue that is bothering your Jeep and get it corrected. 

There could be a disturbance in the sensor’s radio waves

The TPMS sensors are usually attached to the valve stem inside each of your Wrangler’s tires. These sensors utilize radio waves to communicate with your car’s computer. If there ever occurs a disturbance that disrupts the proper working of this signal, it could create annoying problems that make you wanna disable the sensor entirely. 

This essential signal could be disturbed by the presence of tinted windows, excessive snow or ice, and some tire chains. You must analyze the presence of these factors and examine the problem.

It is possible for your sensor to be damaged 

A constantly lighted up TPMS signal generally means low pressure in your tires. However, if the light keeps flashing for over a minute before turning completely on, it could be a symptom of an issue with the TPMS. It is possible that your TPMS sensor may be damaged. Although, there could also be a software issue in your Jeep’s computer that is likely to interfere. You may have to reprogram your computer at a trusted repair shop or dealership. 

Check if your sensor’s battery is dead

The battery that powers the TPMS sensor is embedded in the sensor itself and cannot be replaced. Therefore, you will have to replace the entire TPMS sensor to correct this problem. 

You may be using OEM TPMS sensor along with aftermarket tires 

Your system will not be able to accurately and appropriately respond if you are using OEM TPMS sensors along with your aftermarket tires. Your new aftermarket tires may not sit right with the old sensors. You may have to reprogram them to solve this issue. 

Check whether your TPMS is properly working

Your TPMS warning light will sometimes turn on even when your tires are properly inflated. Sometimes the sensor can be badly affected by the cold weather. So you must ensure to fill up warm tires by at least 4 PSI more than normal if you want to put the TPMS sensor light off. Because cold air is denser than hot air, it can cause the TPMS light to switch on and become the reason behind your irritability. 

It is great if you have manually checked all four tires and the spare tire with the help of a pressure gauge. The TPMS sensor can sometimes get tricked even when everything is fine. You may need to reset the TPMS to solve this problem. 

Perform a TPMS reset 

A TPMS light can become a headache when it doesn’t go off no matter what you do. If you have made all attempts at fulfilling its demands and maintained your tires at the proper air level, there has to be some other factor that is triggering the sensor. Because there is no specific TPMS reset button in Jeep Wrangler, this issue cannot be solved at ease. And the TPMS light wouldn’t go off until you have adequately scratched your head. 

There’s an alternative way to remind this sensor that your tires are at the right PSI level and must go to sleep. This process involves four essential steps. 

Inflate, deflate, and then inflate your tires 

You must inflate all four tires and the spare tire up to 3 PSI beyond the optimal pressure value. Then you must deflate them to a level below the correct pressure value. After this, inflate them to the correct and optimal pressure. 

Go on a twenty minutes drive 

As a part of the reset process, take your Wrangler out for a drive for 20 minutes while driving at 15 mph. Ideally, this should be enough to turn the TPMS light off. If you have filled your tires up to the correct PSI, this short drive should be able to warm them sufficiently. This reflection of reinflation should affect the sensors. 

Employ a TPMS programmer 

When the above mechanism fails, you’ll need to use a TPMS programmer to attain results. Your sensor has probably become faulty and needs to be reprogrammed. This can be best accomplished with the help of your local repair shop. You shouldn’t have to buy your own programmer to correct this issue. 

Once this is done, you can replace the TPMS sensor

In case the TPMS programmer is not able to correct this issue, you may have to replace the sensor itself. Even your TPMS programmer may signal that the sensor needs replacement. Completing this task on your own can be very tedious. It is suggested that you get it done at a trusted repair shop. 

Conclusion

A constant TPMS light may have become a source of irritation every time you take your Wrangler off the road or just out of your driveway. No matter how problematic this light maybe, you cannot just disable the TPMS sensors in your Wrangler. This is illegal and against your safety requirements. 

We have mentioned several tricks that will help you get rid of this problem without causing much or any interference with the sensors. If nothing solves your problem, drive it to a repair shop for an adequate solution. Many Jeep owners get used to this light as just another ‘Jeep thing’. But it is better if you get it repaired so that it can serve its purpose right.
