Easy Posted December 12, 2011 Report Share Posted December 12, 2011 When I've had my 10K oil change, I also asked for tires rotation. All nice and dandy, till I've got a low pressure warning on right-front tire yesterday. So there I was, topping up the respective tire in my garage, until I got it up to 36psi, like the manual (and the label on the door) says. However, when I looked at the EVIC two minutes later, it displayed the 250 kpa on the left-front tire!!! OK, I said to myself, maybe I'm seeing things or something... so I did the same to the right-rear tire. Sure enough, the EVIC showed the increased pressure on the left-front tire this time. As I moved through the remaining tires, it became clear that at some point in time, the EVIC had "lost track" of where each wheel is and my guess is... it probably happened when the tires were rotated a month or so ago. Now, my wife's car (2007 Chevy Impala) has a certain procedure of re-learning the tire locations, but I was unable to find any instructions of how to do it with 2011 Journey RT (or even earlier models, for that matter). Does anybody have any clue how it's done? Quote Link to comment Share on other sites More sharing options...
bramfrank Posted December 12, 2011 Report Share Posted December 12, 2011 There are 3 receivers on the vehicle and it is supposed to track which is where based on relative signal strength - the weakest is the 4th wheel;. It takes about 20 minutes of driving to relearn - have you not done much driving lately? Quote Link to comment Share on other sites More sharing options...
caperinmuskoka Posted December 12, 2011 Report Share Posted December 12, 2011 20 min of driving ...or just 20 min with the motor running? .Caper............ Quote Link to comment Share on other sites More sharing options...

Easy Posted December 12, 2011 Author Report Share Posted December 12, 2011 (edited) Nope, that's not it, the tires rotation happened over 3000 km ago. Did you say the sensors are in the wheels? What happens when you change the position of the wheels? Edited December 12, 2011 by Easy Quote Link to comment Share on other sites More sharing options...
bigtsr Posted December 12, 2011 Report Share Posted December 12, 2011 There is a pressure sensor/transmitter in each wheel they are part of the valve stem assemblies. There are 3 receivers-2 in the front end and 1 central to the rear end. They as others have pointed out supposedly sort themselves out when the tires are rotated during routine driving.

bramfrank Posted December 12, 2011 Report Share Posted December 12, 2011 That's how it is supposed to work. You'll need to have it looked at by your dealer. Quote Link to comment Share on other sites More sharing options...
caperinmuskoka Posted December 12, 2011 Report Share Posted December 12, 2011 Question ...If the rear reciever is central to the rear end ....how does it know the right rear from the left rear? just a question....Thanks........ I thought when the wheels/tires were rotated.............the dealer needed to re-program the location........How long has this been around where they will relocated the proper location themselves.............Caper......

bramfrank Posted December 12, 2011 Report Share Posted December 12, 2011 There's one receiver near each of three wheel wells - the 4th is inferred based on signal strength. With all of the software bugs in the Journey, it wouldn't surprise me to discover that this is just another of them. Quote Link to comment Share on other sites More sharing options...
Easy Posted December 12, 2011 Author Report Share Posted December 12, 2011 Oh, this car has been flawless so far, so one little thing like this won't make me love it less. If I ever get a flat, I'm sure I'll be able to tell which tire it is NOT by looking at the EVIC :-) Quote Link to comment Share on other sites More sharing options...
