TPC inactive message

Recommended Posts

Just bought a 2007 Boxster S - came from factory with optional 18" Caymen wheels. Drove it about 20 miles and it's displaying "TPC inactive" on the dash display. Don't recall display showing "Learning". Believe this is probably the most the car has been driven since the fall - sat on dealer showroom floor thru winter.

Will read the manual tomorrow but does anyone have any further suggestions on what the issue is?

If it's a sensor how do I tell which one it is? I have Durametric tool.

Select the TPMS entry in Durametric (I'm assuming you have version 6.x.x.x), and then look at the various Actual Values for each wheel. If the Durametric can't communicate with the TPMS controller, you may want to first check the fuse (F3 in Fuse Holder B, 15A) for the controller. The controller is located at the front trunk, left side if needed. You can also see how much battery life (in months) is remaining in each sensor (which is what I check every 7500 miles).
