My TPS light just started flashing and is now constant and looks like it isnt reading the rear starboard tire pressure.... i dont have the manual with me.. what the hell is going on?!?!?!?!.. FML is it the tire or the system how do i check it. The tires are at the correct pressure at 60°F, so i know the tire isnt low.. Can i pull the fuse to make it go away.. or will that screw up other systems or throw a code?. |

Gosh Darn your good Scar0! Took the culprit tire off the jeep, put it face down with a slight angle so the stem was down hill. As i let air out a little water came out maybe a teaspoon, aired it down to 15, back up to max pressure (55psi) and down to 33... put the tire back on. Took it off the jacks, put the key in and ....BOOM!!!   ... TPS is reading it again and the light is gone!!!! Thanks a whole bunch!!! Should i have it replace anyway or do you think it will be ok?

Glad you got it fixed up. It should be good to go. Its a semi common problem with the cold weather setting in. Condensation gets in the sensor and causes problems. It can even freeze in there if it is cold enough. If possible always us air that has a condensate water separator in the line when airing up. |

That's unfortunate to hear on a 2012. |

It could still have water freezing inside it. You could try airing down & back up again. |

The TPMS flashing means the computer lost contact with one of the sensors. I've had it happen a few times on other cars too. The fact it is the right rear makes sense because that is the furthest from the module, which is located in the steering column. It may be you got a bad sensor and the battery is dying. |

The RR is also the only wheel well without a transceiver. There are only 3 transceivers RF, LF and LR. The fourth location of the sensor is determined by process of elimination by the WCM (wireless control module). |
