2009 Jeep Wrangler with low tire pressure warning light repair. We set tire pressure to specification, checked for tire pressure sensor problem, installed a new tire pressure sensor, and performed a TPMS reprogram and relearn.
Problem
2009 Jeep Wrangler with Tire Pressure Warning Light on but tire pressures were correctly set to factory tire pressure setting.
Diagnosis
Our Jeep technician performed a TPMS Sensor Failure Inspection. First step is to verify all tires have the correct air pressure as specified for the vehicle and tire size. Next, the technician did a scan test for TPMS sensor communication with vehicle computer.
The technician found that the passenger side front Tire Pressure Monitor Sensor was not sending a signal.
We sent the customer a detailed report of our diagnosis recommending a TPMS sensor replacement, clear TPMS error codes, perform a TPMS reprogram, and retest of the TPMS system. The customer approved the repair and we got to work.
Repair
Our Jeep technician removed the passenger front wheel from vehicle, used a tire machine to dismount the tire bead to gain access to and remove tire pressure monitor sensor from wheel. They cleaned the wheel's sensor mounting surface to prevent air leaks, installed a new TPMS sensor, and remounted the tire.
After installing the wheel onto the vehicle, the technician used a scan tool to place the vehicle into learn mode, and performed tire pressure monitor sensor programming. Next, they did a road test to verify the issue with tire pressure monitor system was fixed. The customer was contacted and told their Jeep was repaired and ready to be picked up.
During this repair a new Tire Pressure Monitoring System (TPMS) Programmable Sensor was installed and the TPMS system was reprogrammed.
Cost
Like most automotive parts, quality and price of TPMS sensors vary greatly. Original factory parts will be the most expensive, but usually the best quality and provide the longest life. Aftermarket TPMS sensors can have quality issues and most shops will sell sensors that have proven to be reliable.

Tips
If the TPMS problem is caused by a dead sensor battery, it will be better value to replace all TPMS sensors at the same time. Experience has shown that TPMS batteries have roughly the same life and when one dies the other sensors will quit soon after the first. Replacing sensors one at a time would require paying for diagnosis and reprogramming each time, rather just once for them all.
If the TPMS problem is caused by a failed or damaged sensor, and the vehicle is less than five years old, it is best value to replace only the bad TPMS sensor.
FAQ
Why do TPMS sensors fail?
There are two main causes that a TPMS stops working and displays a warning light.
First, each TPMS Sensor has a non-replaceable battery. When the TPMS battery reaches the end of its life the sensor must be replaced.
The second cause of a TPMS warning is the failure of the TPMS sensor unit. This failure can be caused by a technical problem with the sensor, or the sensor can be damaged when a tire is removed for a flat repair.
In either case, the TPMS sensor must be replaced and the TPMS system reprogrammed.
Do I have to replace all 4 TPMS sensors at the same time?
If one of your TPMS sensors fails and needs replacement, you can replace it individually. However, if the failure was caused by a dead sensor battery, it's likely that the other sensors are close to failing as well, and it is better value to replace all sensors at the same time. Given the cost of TPMS sensors, most drivers will choose to replace TPMS sensors on an as needed basis, but this may be poor value if the vehicle is seven years old or more.
What is the lifespan of a TPMS sensor?
The average TPMS sensor lifespan is 5-10 years.
