System Structure: Wheels
WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
The TPMS will not work unless TPMS type wheels are installed on the vehicle. There are two different type wheels used. The original equipment wheels have a "TPMS" stamp (A) on the back of the wheel and counterweights (B) cast into the opposite side of the spoke to balance the weight of the tire pressure sensor (C).
