    Maybe an 05-6 change with the can bus electrical.

    I think that’s the case. In looking at the TPMS page from 2004 Tahoe manual, it looks like it is a generic indicator, not corner specific.

    Well I don't have any canbus in my 05 5.3 but I do have the steering wheel controlled DIC if that makes any difference. Tire pressures are at 'Odometer', 'Trip A', 'Trip B', 'Tire Pressures'. And mine cycles through each tire as HiHoeSilver commented.

    Somewhere I read that some aftermarket LED lighting can interfere with the TPMS radio signals? Seems unlikely to cause a low pressure reading though.

    That may be true, or not, but I've had zero issues with TPMS since I had the LED backlighting done to my cluster about a year ago.

    My guess is you have a bad battery in one of your sensors.

    Can't you try relearning your sensors? If one doesn't learn, then its the one with the bad battery.

    Seems like a simple first step to me...

    so the question is, in the 04 yukon l it says tire pressure low? instead of bad sensor? My 08 silverado says the actual sensor is bad.

    My 05 Tahoe currently doesnt have any sensors installed and it says service tire monitor.

    I had one sensor that was on its way out before I put wheels and tires on it and I cant remember what it said.

    I was just suggesting an easy check. Only 2 things I know of you can do on your own without a scanner. One is check pressures and the other is relearn. You've already done the first...

    EDIT: It did say that the tire was low when I had a flaky sensor. Found the picture on my phone and it said low tire pressure and the RF tire read 0 PSI.
