How To Fix Tire Pressure Monitoring System On A Jeep?

A tire pressure monitoring system (TPMS) ensures that all the tires are at standard pressure and running fine. However, any instability can cause tire damage, drive failure, or even tire bursts. Therefore, a faulty TPMS is not an option. So, how to fix the tire pressure monitoring system on a jeep?

You need to ensure there’s no interference with the radio signals. Try resetting the sensor with a 20 minutes drive above 15mph speed to reflect the reinflation. Unfortunately, a damaged battery can give inaccurate readings, and there’s no way to replace the battery. Instead, it would be best if you replaced the whole TPMS sensor.

Don’t ever drive with a faulty TPMS sensor. It would help if you fixed it as quickly as possible. Let’s learn more about it in detail.

What Causes Of Tire Pressure Monitoring System Failure?

Each tire has a valve stem to which the tire pressure monitoring system (TPMS) stays attached. They signal your display whenever there’s a problem, pressure drop, or increment inside the tire. An LED will show you the signals.

However, you need to find out the root cause of TPMS failure and then take action accordingly. Here are the most common reasons for TPMS failure in your jeep:

Radio Wave Interference

The TPMS sensors use radio waves to communicate with your jeep’s computer. Therefore, radio waves can easily face interference because of obstacles on the way.

And the most common interference can be tire chains, tinted windows, ice, snow, etc. Though radio waves have larger frequencies, they can be interrupted by these simple obstacles. As a result, you will face TPMS failure on your jeep.

Damaged Sensors

Whenever you see the light blinking without stability for about a minute, it indicates a problem with the TPMS itself. There’s nothing wrong with your jeep tires.

When the tires are low, it will mean steady tire pressure light. As a result, there’s a high chance that the TPMS sensor is damaged.

However, it can be a software issue. It would be wise to reprogram the sensor from your dealership or tire shop. If the problem remains, it’s clear that the sensor has lost its functionality.


Sometimes we use aftermarket parts whenever it comes to replacing parts. That’s because new parts cost way more than aftermarket parts. As a result, the OEM TPMS sensors are suitable for your jeep.

The OEM sensors can’t provide accurate readings. So, your TPMS will fail. And most of the time, there are no TPMS sensors with the new tires. So, you will have to buy them separately.

Dead Battery

The TPMS sensor runs on an embedded battery. And you can’t replace the battery when it’s dead. So, your TPMS will show failure.

The only way to recover from this situation is to replace the TPMS sensor with a new one.


Whenever the TPMS sensors come in contact with water, they easily damage and show fault readings. And the one and only reason is corrosion. The metal parts and wire system will damage and cause TPMS failure.

How To Fix The Tire Pressure Monitoring System On A Jeep?

Due to the tire pressure monitoring system failure, you won’t get accurate signals for tire pressures. And without proper pressure on tires, there will be difficulties in your driving, and it even causes serious incidents. So, fix the problem immediately.

Equipment Needed

If you fix your TPMS system from professionals, you won’t need any equipment. But when you want to fix it by yourself, you would need the following:

  • New TPMS (if replacement is necessary)
  • PC or Laptop and the essential programs (if reprogramming is required)
  • Wrench and lift tools to inflate the tires

Here are the possible fixes for your TPMS failure: 

Method 1: Replacement

You might wonder, why not replace the battery if it is damaged? But the battery stays embedded with the sensor. So, you can’t detach it. It would be best if you replaced the whole TPMS sensor.

It would be tough to do it in your garage. But if you are capable enough, you must inflate the tires first. Then, buy a TPMS sensor for each tire. Finally, install the new ones and go for a test drive.

Method 2: Reset

Resetting the TPMS is the most common solution to failure. And the majority of the time, it gets fixed. Try these steps to reset the sensor:

  • Step 1: First, inflate all the tires that have 3PSI pressure readings. And deflate the tires a bit below the correct pressure and, finally, reposition.
  • Step 2: You need to drive around 20 minutes with a speed above 15 mph. It would turn the light off and reset the sensor. It would also warm them to reflect the reinflation.
  • Step 3: Open the battery terminal if the light is still on.
  • Step 4: Remove the positive terminal and start the jeep.
  • Step 5: Press the horn for 3 seconds and reconnect the battery.

Method 3: Reprogram

It would help if you reprogrammed the sensor when none of the described methods worked. And the best way to fix it is to contact the mechanic or your local dealer.

Method 4: Ensure Proper Radio Connection

You need to remove the hindrance to get proper radio signals. Ensure there are no tinted windows or tire chains when you have trouble with the sensor. Remove excess snow from the tire and your car for proper signals.

How Much Does It Cost To Fix The Tire Pressure Monitoring System

The cost of the tire pressure monitoring system depends on some facts, such as labor and sensor costs.

Buying an aftermarket TPMS sensor will cost around $40 to $100, depending on the dealer. And remember, the cost is for each sensor unit. However, if you want factory-made and new sensors, you will have to add $30 to $70 to the previous price.

And the labor cost will be $10 to $35. However, it would be best to know if they charge hourly or task-wise. That’s because TPMS replacement requires a bit of extra time. So, an hourly charge may not be the best deal for you.

Things To Avoid When Fixing The Tire Pressure Monitoring System

It’s crucial to avoid some facts when fixing the tire pressure monitoring system on your jeep. First, you must remember that the TPMS sensors can’t be the exact substitute for proper tire maintenance. So, here’s the list of tasks you must avoid:

  • Buying aftermarket OEM sensors won’t be wise unless you are on a budget. They don’t last long.
  • Check the readings from the TPMS after installing the new one.
  • Don’t put the wrong programs while reprogramming if you don’t get the authentic source.
  • Don’t drive with a faulty TPMS sensor thinking that the repair shop is a few miles away. Your tires can explode at any minute.


Fixing the TPMS sensors is a must. And it won’t be wise to drive with a faulty sensor. So let’s check some frequent related questions about TPMS for better views:

Can I find a fuse in the tire pressure monitoring system?

Yes, it has a fuse. The TPMS fuse is located inside the fuse box of your jeep. You will find the fuse box right under the left side of your steering wheel’s dash. There will be approximately 33 fuse slots.

Can I repair the pressure monitoring sensor from a tire repair shop?

Yes, you can repair the TPMS from the tire repair shops. However, you should first find a shop with such facilities, not the local ones.

Primarily, they will repair or replace the TPMS after installing new tires. You might also need to replace the valve core, stem, retaining nut, and several other parts.

How long does a tire pressure monitoring system last?

A typical tire pressure monitoring system can last about 5 to 10 years. It can be damaged and need fixing earlier than the average lifespan if you use it roughly. But most drivers change their TPMS when required, like battery damage.

Final Words

The tire pressure monitoring system signals the LED if there’s any pressure instability inside the tires. Therefore, it’s a crucial element and needs to run all the time properly.

It’s not the best idea to drive with a damaged sensor. Hopefully, the discussion has shown you how to fix the tire pressure monitoring system on a jeep.

You can apply several methods to resolve the issue with TPMS. Try each one until it’s fixed. And always go to the professionals for sensor replacement. Have a safe journey!
