After reading all the responses from the forum members and doing some research this morning, I came up with the following:
It appears that the sensors
are different between Model years, but the exact break is a little ambiguous. CourtesyParts.com references two different wheel sets between model month/years 2009-Sep 2010, and another after Sept 2010, but lists TPMS for only the 2009+ model. So, I researched some more and came across CARID.com which lists two different TPMS sensors for the 370Z as follows:
2011-2012: Brand: ORO-TEK Part Number: OPA-LA0A
2009: Brand: ORO-TEK Part Number: OTI-003
Since the part numbers are different for different model years, I'm gonna go out on a limb here and say this pertaining to my situation:
It seems the dealer I went to has the programming required for the previous TPM Sensors, but not the later TPM sensors, hence, the reason his handheld computer could not read the later 2012 TPM sensor codes. IF that is the case, and I strongly believe it is, then all that is required for us to do when swapping wheels with TPMS already mounted in them, is to ensure that the dealer/shop has the correct programming when we need to recalibrate/reprogram/pair up the new sensors to the vehicle.
I'll be talking to the Dealer again on Monday to see about all this - it may be as simple as him updating the program on his handheld computer. I'll keep everyone posted further as I get additional info.
