A-Premium 4PCS Pre-programmed TPMS Sensor Tire Pressure Monitoring Sensor - Compatible with Chrysler, Dodge, Jeep Models - 300 2009-2016, Charger 2009-2015, Challenger 2008, Magnum, Gladiator - 433MHz

I purchased this A-Premium 4-pack of pre-programmed TPMS sensors after one of my rear tire sensors started failing. While I was driving, the reading suddenly jumped from 38 to 0, even though I had checked my tires before leaving and knew the tire was not flat. A few seconds later, it returned to 38, then repeated the same issue over the next two days. Since I was already planning to have new tires installed, I decided to replace all four sensors at the same time because I suspected the others might not be far behind. I ordered the sensors on July 4th, and they arrived on July 8th. They fit my 2014 Dodge Charger RT, were already programmed, and I have not had any problems so far. Other customers should know that replacing all four sensors during a tire change can save an extra trip back to the shop if the original sensors are aging, especially since TPMS sensor batteries typically last 5 to 10 years and I have owned my car for 10 years.

Once installed the nut and tightened if you remove it would not keep the valve tight after a couple days you start loosing air, ONLY if you install and remove which was my USER ERROR

I learned the hard way that Jeep had changed the sensors half way through the year (June of 2021) due to Covid disrupting the supply chain. My Jeep was built in April of 2021 and, when I bought new tires I also replaced the tpms sensors. Unfortunately, the first set I bought (for a 2021 Jeep Gladiator) did not work. It took some research to find these and they work perfectly! Of course I had to pay again to have them replace the first non working set.

Perfect fit for my 2020 Jeep Gladiator. Easy to program. Leave key 10ft from vehicle for 15 minutes, then drive at a constant speed of 15mph or better until the light goes out. Easy peazy.

Timing is always difficult on these types of items. One must schedule time to get the TPMS sensors installed in the tires, get them programmed if necessary, and then run them for some period to evaluate them and their performance. These work similar to most Dodge TPMS sensors, as they self-activate and the car recognizes them after some number of miles, pressure change, etcetera. So far they seem to work reasonably well. The pressure indicated seems to agree within a pound or three of a manual tire gage. The tire shop reported nothing unusual during installation, and so far aft a month of use, the batteries and the units still operate. As compared to the original factory units which performed for 10 years, only time will tell. Should they fail in under 5 years, I will report back..
