I searched and searched and couldnt find an answer to my problem so hopefully someone can help out. My readout on the TPMS gauge on the triple gauge does not match what my tires are set it, and its off by about 4 to 5 psi. This causes the low pressure light to come on much sooner than it should. Is there some sort of calibration to make the gauges match the sensors? I believe 2 or 3 of the sensors are still original but even the new sensors I've installed don't match so this doesnt feel like bad sensors to me.

Welcome- the TPMS seem to be set for sea level and our high-altitude city seems to throw them off. This problem has existed since the Z33 was introduced and to my knowledge, has never been solved. I simply inflate my BFG G-Force tires about 5 pounds higher to compensate.

This makes sense. I moved to Colorado a couple years ago and it seems to get farther off than it used to be. I assume no way to adjust that value, I have consult software I'll try to dig through it. I keep the tires around 35 or 36 psi but cold mornings will set off the low pressure light. I guess I just need it to start snowing so I can leave the Z in the garage for a while.

Good luck with Consult- I use UpRev's Osirus and never found any methods to reprogram or calibrate TPMS. Let us know if you find any solution.

Also, nice call on leaving the Z in the garage when it starts snowing New Year's Eve.

What kind of gauge are you checking tires with ? My accugauge works very well

Hah- I've got everything from a racing tire gauge that gives accurate pressures down to the 1/4 pound to the truck stop pencil type. But the OP wants to get the OEM TPMS gauge to display accurate tire pressures at altitude. A mile high home here in Colorado makes that difficult, and that's why I chimed in.

May I make sure that we just buy triple gauge dash in middle and plug in. No need flash or anything more so it is automatically work? Thanks

According to this thread, yes.
