TPMS Problems

HI All. I've read a lot about the TPMS system not working....I'm in the same boat. 2007 GMC Sierra SLT.

 

I've tried every which way to get the horn to chirp and it doesn't. Air decrease, air increase, 5 seconds and wait, 10 seconds and wait...30 seconds and wait....rub my belly and pat my head...etc

 

Anyway, nothing works so I figure I'm choosing between either waiting a day at the dealer or not having an operational TPMS system.

 

Or....I read somewhere that the parking brake must be set. I haven't done that. Is that a MUST do, or SHOULD do?

 

Has anyone relearned tire positions without having the parking brake set? I just don't want to drive all the way to the free air gas station for the 10th time to find out! :)

 

Thanks in advance.

I think there was an update to fix that issue on some of the earlier '07s that would not go into learning mode properly. However, you do not need to set the parking brake. Any reputable tire shop will do your reset for cheap or no money at all.

The TPMS sensore do wear out. I had a set of rims from a H3 I used on my Colordo and one tire just had a bad sensor. I had it replaced and no mor issues.

 

The batteries in them die.

On my 2011 which is not supposed to be able to use the air out method, I successfully set them this way:

 

Wait at least 20 minutes with no tire movement or pressure changes (including the set just removed if you are swapping winter/summer).

Have the tires aired up above the low pressure threshold - say 32-35 PSI.

When the light indicates the wheel to synchronize -

quickly let out a lot of air so the sensor goes below the low pressure alert value.

 

Works for both my OEM and aftermarket set. It may seem like it is taking forever but keep letting air out until the horn chirps.

 

I never set the parking brake.

I took my 08 to the dealer since dic was always showing low pressure. Claimed they reset due to the larger wheels but the dic is still the same. Does anyone think its the TPM bad because they need replaced? Dealer said all is normal and they have no clue. Any ideas?

They don't work but the dealer says all is normal? Sounds like they just don't want to be bothered with you.

You could buy an aftermarket TPMS and see if it can be paired with the truck to see if yours are bad or if the problem is with the receiver unit.

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
