Are you experiencing Jeep tire pressure sensor problems? Have you recently done an aftermarket wheel and tire upgrade? Are you getting alerts that some tires aren’t working anymore? Have you been to the dealerships to have it checked out, only to find the TPMS error to reappear a few minutes from driving from the dealership?
If you are 100% sure the valves have not been replaced with regular ones, you need to simply drive the Jeep for 10 minutes at a constant speed, to allow the sensors to relearn the tire pressure. Pay little attention to the actual readings for now since these will fluctuate a bit during driving and stationary resting numbers.
You need to also determine if the problem lies with a sensor or with the TPMS module. You can do a simple tire rotation to determine where exactly the problem lies. More about that later.

Jeep Wrangler TPMS Sensor Not Reading
The Jeep Wrangler TPMS Sensor Not Reading can be a frustrating issue for owners. When the TPMS, or Tire Pressure Monitoring System, fails to read the sensor, it can cause concerns about the safety and functionality of the vehicle.
There are a few possible reasons why the TPMS may not be reading, including a faulty sensor, low battery, or interference from other electronic devices.
Owners need to address this issue promptly to ensure the proper functioning of the TPMS and the overall safety of their Jeep Wrangler.
Is your Jeep tire pressure sensor not reading? The TPMS uses wireless technology with sensors mounted on the wheel rims. These are used to monitor tire pressure levels. These wheel valve stem sensors transmit tire pressure readings to the receiver module. If that is not happening, you will experience any of the below symptoms.
- The system shows reading is unavailable
- The alert light remains on
- Reading signals are intermittent
- Not receiving signals on all 4 wheels
TPMS reSET and Reprogram
To rectify the issue of a Jeep Wrangler TPMS sensor not reading, one can try performing the 2019 Jeep Wrangler TPMS reset procedure to recalibrate the system and resolve any malfunction.
- Visit your local dealership to have the TPMS module scanned and possibly reprogrammed, and all-wheel sensors tested and reset.
- They have a portable device to do this without physically having to remove any wheels.
- A decent dealership shouldn’t charge you for a simple scan.
- Reprogramming each sensor will be charged for.
The tire pressure should vary with external temperature by roughly 1 psi (7 kPa) for every 12°F (6.5°C). This means that when the outside ambient temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure.
The tire pressure is determined after the vehicle has been parked for a minimum of three hours. Alternative if the vehicle has been driven less than 1 mile (1.6 km) after three hours.
If you managed to determine one or more of your sensors are defective, replace them with a genuine OEM part. Aftermarket sensors have proven to be more unreliable. There are 3 sensors located on the chassis that manage the 4x TPMS sensors on each wheel. Your spare tire sensor is inactive until it is replaced by one of the wheels.
The replacement part number is OEM:433 – Schrader 20398.
Low-Pressure Warning Limit
If the tire pressure drops below the low tire pressure warning limit, the driver will be alerted. Low External temperatures will trigger the alert as well as a deflated tire.
- The onboard alert will continue until the tire pressure is at or above the recommended cold placard pressure.
- When your Tire Pressure Monitoring System Warning Light appears, you need to increase the tire pressure immediately to the recommended Cold placard pressure before the TPMS Light disappears.
The TPMS system is quite intelligent and can determine all the required info from the 3 chassis sensors. The WCM (Wireless Control Module) receives the info from the sensors, which is then relayed to the driver onboard.
- The alert warning on the dashboard cluster will remain eliminated until the tire is inflated to the placard pressure.
- All this information is processed within seconds of the vehicle driving and all is done automatically.
Disconnecting the Battery to Reset
Owners have attempted to reset the TPMS monitoring system by disconnecting the battery. If you disconnect the negative battery terminal for 5 minutes – all electronic modules and capacitors lose their memory.
- This is not only applicable to your TPMS system but every electronic circuit on your vehicle.
- This procedure will also erase all onboard error messages.
As a process of elimination exercise, you can have the wheel with the faulty signals rotated with a wheel that has a good signal. If that same wheel is still giving problems at the new location, you’ve identified the wheel valve sensor to be faulty.
- Alternatively, if you’ve rotated wheels and the wheel that was behaving, now gives problems where the previous wheel did, you can safely conclude, that you have a faulty chassis sensor.
Removing the TPMS Completely
Another option, which is not supported or endorsed by your owner’s manual, is to completely remove the TPMS from the valves and replace them with regular valves. Use a TPMS programmer to switch off the TPMS system.
Jeep Wrangler TPMS Module Location
The Jeep Wrangler TPMS wireless receiver is located on the chassis cross member. The receiver gets its information from the dual-axis accelerometer in the wheel sensors. This is used to determine the front and rear position through its signal strength.
These are highly sophisticated sensors and should only be replaced by genuine OEM sensors. Avoid the cheap versions.
Both the Wrangler and Jeep Gladiator TPMS not reading is a common issue that Jeep owners have encountered, leading to frustration and uncertainty about tire pressure monitoring. When you adjust the tire pressure, you’ll need to drive the vehicle for up to 20 minutes at speeds above 15mph (24km/h). This is necessary for the TPMS to receive the updated information.
