    Weird TPMS activity

    Today my passenger rear started indicating the tire pressure was increasing slowly. later increased to the point that it started flashing. passenger front seems to be losing air according to the sensor but not by feeling the tire. Even added some and it didn't go up.

    anybody got any clues??????

    appreciate any/all replies

    It sounds like you have a failing tire pressure sensor.

    Yeah yeah when it rains it pours. My alarm doesn't work, my sunroof is messed up., between my work schedule and all the rain this last week I have not been able to get it to the "stealer" and now this. I know its not going to be cheap. only had it abt 6 weeks Love it though, waiting on rest of revshift stuff so all gets done at once.

    Rock Auto (mail order) sells sensors (315 mhz) for a little over $30.00. Any tire store can install them for a few dollars. Finally, some tire stores even carry them, and most tire stores know how to program them.

    They should - the sensors for the 03 Deville are also 315 mhz. (According to the Rock Auto listings.)

    Any way other than installing to find out if they work? I think I read somewhere their lifespan is abt 10 yrs.

    It is my understanding that you test the batteries before installation by seeing if they will respond the the programming sequence, but you cannot verify the accuracy of the tire pressure sensing ability without mounting them. I would drop by a tire store or even a dealer and ask - I have had both help me with TPMS issues for no charge. (And yes, the life expectancy is 10 years.)
