TPMS problems.

[fishinrobbie]

is there any one who can tell me how to turn this thing off or by pass
i want to put on 99 ford rims and they are telling me it will cost $110.00
per tire to change just the part on the rim holy cow $500 just to change rims my god are you kidding me just wondering if any one else had this prob thanks to all for any :exporange

Welcome to this forum! I've moved your thread into the tires & wheels section. You could transfer the sensors from the old wheels into the new wheels. Make sure that you keep each sensor in the same wheel. If not, you will have to reprogram them.

WOW! I just replaced all 4 rims on my '07 and the sensors were only $32 a piece. Another $28 to get the reset/relearn tool from RockAuto, and that's it...

The reset tool is a strong magnet. What kind of tool does Rock Auto have?

MOTORCRAFT Part # TPMS19 {#8C2Z1A203A}

I am not sure a strong magnet works with the sensors that Ford uses, since they are the banded type, rather than the ones that basically get mounted on the valve stem.

Yep, that's the one.

Is there anything battery powered (electronic) on this tool? I wasn't able to find a picture of it.

Yes, it is battery powered:

It looks like the new TPMS systems are more sophisticated than the earlier versions where you only needed a strong magnet to reset everything. I assume that this new version transmits a specific frequency or a code to clear the unit?

From what I've been able to gather and extrapolate from various forums and google searches, I don't know that it is that much more sophisticated. I think that part of the issue is that we don't really know where the sensor actually is. Technically, an installer is supposed to position this sensor 180 degrees from the valve stem, but you never really know. With the type of sensor that gets mounted on the stem, that's a different story and a relatively low-power magnet can generate the field necessary to put the sensor into "identify" mode (so to speak!). If you knew exactly where the banded-type sensor is, it is possible that a strong magnet could trigger the sensor into indentifying itself to the master module... This is all speculation on my part.

Keep in mind that one of the reasons our system is more complex is that is has the ability to tell you which tire is faulty. There are manufacturers that don't go to that level of sophistication: as long the master module gets 4 signals, it gives you a pass. The up side of that approach is that you don't have to retrain the system even if you rotate the tires. In our case, well, we're kind of screwed...

thank you for the information
this sounds like some geek who never drove or never knew the working end of the air hose came up with this plan
so he never needed to check things in his own car !!!!
but because he's a jack ass we all have to pay now

for anyone who is still wondering, all banded type tpms or placed EXACTLY 180 degrees from the valve. they are little *******s and like to snap easily. i used to work for just tires and had nothing but problems when trying to change those. on the newer explorers they should all be mounted on the valve stem. this would make more sense but then again, it is a ford
