    Default Tire pressure problems

    This all started by changing out the battery. After about 200 miles tpms fault started, all 4 showing dashs, then they started reading correctly again, few more miles dashs again, relearned all sensors ok, 100 miles or so,l same thing. brought the car back home, dropped all the air out, refilled with nitrogen and performed a relearn again, seemed to work, all sensors showing correct pressure, drove it again around 100 miles it's back, but shortly started reading correctly. Any insights would be helpful.

    Having issues with my TPMS also. Installed new tires. Set my sensors and after a couple days boom my senor fault went on and no pressure showing on all 4 corners. Got out ..looked ..had air.
    Tried to inflate deflate relearn ..etc etc still the same shit.

    Was told that this is a sign of a sensor failure. How do you tell which one I asked .. You dont. So I guess I need all new sensors ..not worth the BS IMO. So I have the fault showing.

    I've changed my battery after 5 years. New tires, same sensors. I'm not having that issue. It's hard to believe that all 4 sensors quit at the same time.
    Rest in Peace Charlie!

    Exactly ..After never having an issue before and all of a sudden .. Called a different service dept ..they did say 1 fault could cause all of them not to relearn and cause the fault for all 4

    Go into Engineering mode. There it will show the tire pressures and the bad sensor will read really high. (148 psi if I remember correctly)

    p.s. Order on the tire pressure settings in Engineering mode : LF LR RF RR

    I have had two go bad one at a time, now about every 100 miles they all go blank, they may come back in 10 miles or 100, no pattern to it, resetting doesn't work when they are all dashes, I guess I will replace the remaining two and post the outcome

    It's the battery in the sensor. They don't last forever.
