Ok guys, not going to say who told me to do this, save to say he is one to know what he's talking about, but he gave me an idea on how to keep the TPMS happy.

I was at a dealership talking to a guy about trucks, and kinda half heartedly complained about my TPMS. Not a big problem, it's just that I like all my dummy lights out, clean dash and all. He suggested that next time I balance and rotate my tires that I take all the TPMS valves out of the road tires, and tape, or just throw them in the spare tire. Run the spare at the happy psi and put regular stems in the road tires... presto!

Now don't kill me if for some reason the sensors can tell if they are in the rim or not and it doesn't work, but it seems plausible and on my short list!

It'll work, but I wouldn't due that due to rotating the spare in. If you ever use the spare, you'll beat the sensors to a pulp inside. I've heard of some sealing PVC with the sensors in them and pressurizing it with 40psi. I'd consider that if i didn't have a tuner..

 

yeah that would work i would think... but might be eaiser just to get a procal and turn off the light

 

I know some people with sport cars/tuners that swapped their wheels. They put the TPMS sensors in a length of PVC pipe sealed it and raised the pressure to the proper amount and secured it under the hood.

BUT... I also have a buddy that works for BMW, and their system knows where each sensor is (L/F, R/F, L/R, R/R) and if they're all in one spot then the light comes on for a false reading. I dont know if Chrysler's is the same.

Would a low spare tire on the JK's set the light off?

 

Oh yeah, I agree about the procal. It was just a quick easy idea I heard that I had not seen on here yet. Didn't know about the pvc pipe, that's a good idea too.

 

Get the ProCal for $150 and call it a day. Set to 0 and install rubber stems. Done.

 

The Superchips Flashpaq wil adjust your TPMS & alot more.

Worth every penny.

 

A low spare tire will indeed set off your TPMS. It happened to me soon after I got the Jeep, light kept coming on, I had checked all my tires (except spare) a bunch of times and everything was fine. Checked my spare and it was 3 PSI off what it should have been once I fixed that the light went away! YAY for stupid sensors that are a pain in the ass!

 

This is correct, as far as I know.

The simplest way to manage your TPMS is with a ProCal or similar programmer. I've been very happy with my TPMS system ever since I got a ProCal.

 

The engineer in me wants to know: Why would they design it that way? Stop and think about it, not only must you include the necessary accelerometer feature (which must be in the sensor, duh), but you must also include some timing logic or else the TPMS will go off when parked at a long light, etc. Or does it? Anyway, why?
