AICEL TPMS Relearn Tool EL-50448 for GM Tire Pressure Sensor, Orange

This TPMS tool works as it should. When using it, point it at the sensor next to the tire not the rim. Also, if you have a new sensor that doesn't want to read, give it a couple days of driving. On my Silverado, the right rear sensor wouldn't read. And the computer wouldn't acknowledge the 3 that were read. So I tried it a few days later and it read the 4th sensor. Hope this helps someone.

Didn't work - had to return it. I read other reviews and they were mixed so I decided to try myself. But it was no go so it went back.

Very great item to add to your tool box and saves you from going to pay for a program at dealerships or tire stores, works perfectly fine on your resets if needed and very easy to use, while programming you’ll her it beep and car will actually honk for you as you reset it on tire stems, price very budget friendly and a great purchase for me, very fast shipping

Probably works, but with no clear instructions, how can I use it? It says to be sure the "learn" function is on in the car, but gives no clue about how to do that. Pretty useless...

This device worked great for 315mhz sensors on both 2015 malibu and 2008 Yukon XL. The only knock is, after finishing, I wanted to take out my 9volt battery. When I took it out, it to bent the 2 battery contact prongs and they would not contact the battery when re-installed. I was able to bend them back with a plastic tool but this is caused because of the design of the battery compartment. Don't let this keep you from buying, it did wake up both type of sensors I bought. Changing out 8 tpms sensors was a workout for this old man. Saved a lot of $$$

Works as advertised. Completed the relearn in less than a minute.

I bought this and tried it out and even bought another tool to try and clear my light and it was not effective at all for my 2020 Subaru Forester.

This little tool saved me having to replace the Tire Pressure Sensor located inside the tire at the valve stem. Once the batteries got installed, this device worked like a charm, starting at the front left and working clockwise with each tire, following the instructions that came with the unit. The reason I bought it was because the hole-in-the-wall tire shop said the TPSensor inside one tire wasn't working and would need replacing. It did not, the shop manager was trying to scam me. I had a feeling when the dash computer tire pressure only had no register for all the tires. Will be avoiding their business now. Easy to use folks, just follow the simple instructions. YouTube also has references for "Tire relearning procedures".

No instructions probably because TPM setup is vehicle specific. I used YouTube to work out what to do with my truck. I should have bought this years ago
