Are you sure they are oem? Gm and aftermarket sensors don’t usually mix. And yes I know it says oem but eBay does lie.

The pictures have the correct part number on the label. Like Jason said, the seller has good feedback.

I need to figure out how to break the bead on the tires so I can install these myself.

Breaking the bead isn’t hard. You let out all the air and stomp/jump on the area next to the tire/rim.

Putting it back on, as I’m sure you’ve seen seems a little harder.

Hairspray and a grill lighter

This is interesting.



That looks like an H2 wheel.

You have to be quick with the air to fill it to though is the problem. That expansion blows it on but then comes a vacuum from it going out without o2. So if your not quick enough with the air then it doesn’t matter.

If it sets on the rim correctly, it shouldn't come back off. Otherwise you wouldn't need tools to UN-set it in the first place.

It looks like it might be possible to use a large bore air blow gun in the tire valve after you've removed the stem core. I might try it on the spare tire just for the hell of it.

That’s how they seat them at tire places. Take out the core and use lots of pressure with lube.

I’m correct on the stuff with fire, fast and loud did a horrible job at doing one and they were using a ton of flammable fluid. He didn’t get the air in it like 4 times soon enough and it wouldn’t seat.

Dad can show you how to break down a bead. He's got a 'technique'.

Literally first 5 seconds of this video. Just make sure you have an empty tire before you do this.

Similar, but my dad uses a board to get up and on to the tire and place it next to the rim properly.

So on the topic of TPMS, I wanted to make sure the sensors were actually bad before I committed to paying to replace them. I say that because I had the body control module (home of the tire sensor receiver) out of the truck when I had the dash out. The back of it looked like it may have gotten wet at some point. It was either that or just solder flux residue from when it was made. I couldn't be sure.

So I picked up a potentially broken GM tire sensor tool on eBay. It was cheap enough and I had a good guess what was wrong with it. Turns out I was right. The rechargable battery packs were terminally dead, and the kit didn't include a charging cradle. The terminal inside the device was damaged due to the dead pack corroding it.

Fortunately you can use generic C batteries with these things. So I fixed the terminal and dropped in some recharagable C-cells from Amazon. It fired right up.

All four of the sensors are bad. The spare tire seems ok though.



The other cool thing about this is it has a simulation mode. You can basically put it in reverse and have it pretend to be each wheel, to see if the BCM can successfully do a sensor relearn. It did. The BCM is ok.

I hope to never need it, but it works on the Corvette too. I should try it on the Mazda.

That’s very cool!

Jeff and a new toy!

I like my toys

I found out later there's an identical OTC tool that works with multiple brands. It looks like exactly the same hardware. I want to find out if I can load the OTC software on mine.

Only Jeff buys a GM tire pressure monitor sensor tool and the contemplates hacking it

This. Lol.
