Lots of fixes done but have question on tire pres sensors

[Ken Dalton]

I have a 08 Tahoe LTZ and after looking into upgrading to a 2016 or so I realized I didn't want to spend $30k or more so I just put some money into my 2008.
Arnott Air shocks, struts, brakes, full tune up, new mirrors, sway bar bushings, etc etc. It drives SO much better.

But I had 1 tire sensor suddenly go out. I tried to reprogram it thinking it really didn't break. During the reprogram process that same one wouldn't register so now the 3 other won't register. So I went from 1 not working to all 4 not working & the dash just has the air warning on it.

I'm not going to worry about it until I get new tires but wondering if I could just reprogram the tires and use 1 tire twice to trick it??

Also, when doing the front driver strut I found a black plastic hose just hanging down. It looked plugged up and I don't know what this is for. Sunroof drain maybe? It was hanging down close to the brake caliper and I moved it way by the chassis. (no its not a brake line...feels more like an air line...thin plastic)

thanks for any help/advice.

Here's a tip, speaking of tire sensors...Don't use the Fix-a-Flat aerosol sealant. It screws up the tire sensor to the point that you need a new one. Even if it states on the can that it won't damage the tire sensor...it will and it does. I had a can that was "supposedly" okay to use with the sensors and in a pinch I had to. I repaired the tire and soon after, like the next day, the tire sensor warning came on and never went out. Luckily my tire center took pity on my dumb a$$ and replaced it for free. Lesson learned...

2008 sensors are probably about done, the batteries last about 10 years on average, sometimes more. And no you can’t get away with using 3. Honestly I would replace all 4 with quality AC Delco parts if you want them to last another 20-12 years. If you do one, the others are going to go out one by one in short order. The batteries can’t be replaced either. I just replaced all mine on my 08 Silverado.

ok, I didn't' realize they took batteries but of course they do! Yeah, I will for sure do all 4 at once. I was just trying to get rid of the nag warning until I get tires (next 3 months) but I guess its not a big deal.

I did buy some cheap eBay sensors for my Cad CTS and none of them worked so lesson learned there. Tires are already installed and eBay seller just says "sorry, got a bad batch".

I highly recommend Titan TPMS. They are affordable, work well, and their customer service is awesome.

The ACDelco TPMS sensors are only $15 each on amazon.

Speaking of lesson learned, don’t bother with purchasing TPMS sensors except from the tire installer.

The supposed ligit seller on Amazon sold me four outdated units with questionable batteries. The greedy scammy seller forced me to pull the 1st two out and have the shop charge me for their parts, plus labor.

If your tire dude installs them, he’s on the hook for replacement & labor (tire removal + mount + balance). If you have to to one, do all four and save the headache later.

A tech II scanner will provide TPMS battery voltage if you’re ready to step up to a long term investment for the truck. It’ll also reprogram all the TPMS to each corner.

I checked around and the tire dealers I spoke with wanted $400 to replace all 4 on my 2005. So, I just ignore the TPMS message in the DIC.

For $100 you can get a little box that will send a signal for all 4 tires fooling the TPM System and not have to worry about ever replacing the sensors or having the light on. I believe @Jolly Roger uses one of them.

Buy the AC Delco sensors on Amazon for about $60-80 and take them in. All they have to do is break the bead to install them, they don’t need to dismount the tires. They should charge about $15 a tire.
