    i tried to reset after the driver frt starting going in and out. Then I rotated and have tried three times since to reprogram. Its hard to get to the dealer due to when I work but I think I may have to make a trip. Will their computer be able to reprogram even if it isn't working manually?

    if the sensor has gone bad then nothing will work ... sounds like that may be the case here...

    Re: Resetting the TPS's

    if there's no double honk then it probably didn't take--and what it's showing for "--" as the driver front tire is actually the driver rear tire that's not responding. what's the battery life on these sensors?

    I figured that was the case, but I do get a honk on Driver front when I let pressure out. That indicates it is getting a reading Correct? But yet it still reads "---". The pass. rear that was low still read ~33psi even tho it only had 10 psi. I don't want to replace the wrong one and waste money.

    Thanks for the help.

    Just a little more info, I purchased the car back in Sept '10 and the Dvr frt was not reading at the time of sale. Two days later it came on and stayed on for weeks with no issue. Then went out and has not came back on since. Which is why I have tried to re-program manually and rotate and re-program. Really have no other issues with the car electronically with radio or the like.

    Re: Resetting the TPS's

    One of mine went bad last year. Front tires both honked and were programed. But when I got to the RR it would not honk. So I pulled out one of my winter rims, used it in place of the RR. It honked and I moved on to the last rim (LR). Now I have three reading correctly, with "--" in the RR.

    What I'm saying is, if one is bad, you'll have to skip that one and the next tire will show in its place. Or just move it to the LR (if you can) and the other three will read correctly until you can get a new sensor.

    rfid sensors don't use a battery, they get their power from the signal that is transmitted to them from the reader.

    Just a guess, but perhaps it reverts to the previous programming if your attempt is unsuccessful. Which is why it shows the wrong wheel as having a dead sensor.

    Re: Resetting the TPS's

    the car doesn't know you've rotated the tires until you fully program all four tires... so the readings are for where the tires used to be... unless i'm misunderstanding the situation

    edit: Aurora40 is correct... it won't shuffle around the location of the tires until you get the ending double honk ... notifying you that the car knows which tire is which and that they're all reading okay

    Re: Resetting the TPS's

    Does it have to be mounted on the car to be programmed? Meaning, if I use my spare to "fool" the system (leave in trunk, until I get the sensor replaced or exchange rims). That way I can at least get to comp mode or turn off stability sys. Not too concerned if it is actually reading the real pressure. Just want to use those functions.

    No, it doesn't need to be mounted. As long as the car can see it electronically you're good.

    the sensors do have batteries in them, most manufactures expect 7+ years of function from them, dont know what gm says itll be though. i agree you just have a bad sensor in the lr wheel. since it doesnt monitor the spare, id just take it somewhere and have them swap the two sensors, then you should be able to program it up fine and have it be functional

    why would the tire's RFID tags have batteries in them? I don't see why our tires would be active RFID's for the function they serve.

    I don't think the TPMS sensors are actually RFID. They communicate on the same channel that the remotes use, just a standard radio signal. RFID is usually much closer proximity than the sensors operate at, anyway.

    Re: Resetting the TPS's

    there are no initiators or anything, just the sensors an antenna, and the module(which i believe is integrated into the i/p) the sensors know when the car is moving based on centrifugal force, and send signals that are picked up by the antenna module when they think they should, at different time intervals based on whats happening... less often when stationary, more often when moving, and they are forced to repeat their signals when pressure changes, thats why they can be programed by changing the pressures, once in 'learn' mode, the module just looks for the repeated signals as ties it to a wheel position
