ACDelco 25773946 Tire Pressure Monitoring System (TPMS) Sensor

These units have their batteries sealed inside (non-changeable). I was a little concerned purchasing them and not knowing the manufacture date. However, when I received them, the date code was very recent (only 3 months old, my last ones were still working after 11 years, but I figured it was time to change them with this tire swap). The TPMS units were the OEM parts in perfect factory sealed condition and worked perfectly when installed. The price was great from Amazon ($15 each less than the best dealer or parts store price) and they were delivered as expected. I couldn't be happier with the purchase.

Part works well and is priced well, but didn't come with the nut to secure it to the wheel. They probably expected you to have the nut from the replaced part, but if you don't.....

Good product and for the price, can't beat it from a long shot. Those magazines want 100.00 for this item. I saved 65 dollars buying from these people.

Got a set of 4 sensors and had them installed. Dealer could not get them to work because of weak batteries.

ordered another set of 4 sensors and the dealer checked them before trying to install them, found all 4 sensors

also had batteries too weak to activate the tpms. Returned the second set and ordered a set of dorman sensors. The dorman sensor batteries were ok and they worked like they should have when the dealer installed them. Lots of wasted time making 3 trips to finally getting the results that should have happened the first trip to get the sensors installed.
