Sometimes the Jeep wrangler Tire Pressure Light won’t turn off despite having enough air pressure in your Tire. It happens because the TPM sensor can’t fully sync with your Jeep’s computer. That time you need to reset the Tire Pressure Light.
To reset the Tire Pressure Light on your Jeep Wrangler, ensure all four tires have the recommended PSI, then drive the car for some time. If that doesn’t happen, you have to use the OBDLink MX+ TPMS tool to reset it. Just connect the cable to your car and use the mobile app. And the tire pressure will reset automatically.
But if the issue still persists, you need to change the TPMS Sensor. No worries; keep reading to learn more. Resetting tire pressure is not rocket science.
Why Won’t My Wrangler’s TPMS Go Off Despite Having The Right Pressure?
Usually, the Tire Pressure Light indicator goes off when you put enough pressure (35-38 PSI) in your Wrangler’s tire.
You will find the PSI requirement at the bottom of your Wrangler’s left door. However, sometimes, it won’t go off as it should. Here’s some reasoning behind it:
1. Replaced Tire
If you replaced your original tire with aftermarket tires or second-hand ones, the TPMS sometimes wouldn’t sync properly with them. And you will face tire pressure light issues with your Jeep.
2. Malfunctioning TPMS
Sometimes the Tire Pressure Monitoring System is damaged while you are driving your Wrangler on rough terrain. When that happens, the pressure light won’t go off. But how can you know?
Well, when the pressure light flashes for 50–60 seconds before staying on, that means there’s an issue with the TPMS itself, not the tires.
3. System issues
Sometimes, after changing your tire, the TPMS won’t properly sync with your car’s computer. That time, the pressure light gives you a false alarm for your tire pressure.
4. Battery Problem
When the battery of your Tire Pressure Monitoring System is dead, It can’t send the data properly. At that time, the pressure light won’t turn off despite having the right pressure in your tire.
Unfortunately, you can’t change the battery of your TPMS, because the battery is embedded permanently in the sensor.
5. Disturbance with Sensor’s Radio Waves
Jeep installs the Tire Pressure Monitoring System in the valve stem inside each tire, and they use radio waves to send data to your Wrangler’s computer.
Sometimes those radio signals can’t reach the computer because of issues like tinted window glasses, tire chains, snow, hailstorms, etc. In That case, the tire pressure light doesn’t turn off.
When any of these happen, you need to reset the tire pressure light on your Jeep Wrangler.
But how can you reset the tire pressure indicator in your Jeep Wrangler? Or Does the Jeep Wrangler have a TPMS reset button? Continue reading to learn more.
Is There a TPMS Reset Button In The Jeep Wrangler?
Unfortunately, there isn’t a reset button in the Tire Pressure Monitoring System of any Jeep Wrangler model. So if the TPMS shows continuous errors, you need to replace it.
However, do not jump to a conclusion yet. Though the Jeep Wrangler doesn’t have a TPMS Reset switch, there are some steps you can take to reset the tire pressure light before replacing it.
Read the following section for details.
How To Reset Jeep Wrangler Tire Pressure Light
There are some methods to reset the Jeep Wrangler’s tire pressure light. You should try them before changing the TPMS sensor. Here are the solutions:
Method 1: Reinflate Your Tire’s Air & Drive The Car For 15+ Minutes
To reset the tire pressure indicator, the first thing you need to do is put about 3 to 4 PSI over the recommended value, then drop the pressure to the safety level. After that, drive the car for 15 to 20 minutes above 50 mph (80.47 km/h).
Then the car’s tire pressure light will turn back to normal.
Method 2. Use The TPMS Reset Tool
If driving your car doesn’t reset the tire pressure light, you should use a 3rd-party TPMS Reset Tool. Because the Jeep Wrangler doesn’t have any TPMS Reset button.
In my case, the OBDLink MX+ gave better performance than other alternatives. However, you also need the TTXSPP Cable Adaptor for Chrysler to connect the device to your car.
Read the following steps to use the device:
- Connect the cable adaptor to the OBDLink MX+ device
- Go underneath the steering wheel and detach the two cable connectors.
- Connect the tow port of the TTXSPP Cable Adaptor for Chrysler with your car’s cable.
- Check for the power light in your OBDLink MX+ device.
- Open your phone and open the OBDLink app.
- Select your car from the app interface.
- Choose your OBD adapter from the list and go to Adaptation.
- Select the TPMS settings.
- Lower the tire pressure or deactivate it as you see fit.
- Disconnect the car cables and put them back in your car.
And after completing the steps, the tire pressure light will reset and won’t bother you again.
Last Solution: Replace TPMS Sensor
If any of the 3 methods don’t fix your issue, your car’s TPMS Sensor is severely damaged. So you need to replace that to reset your tire pressure light.
