Are the TPMS sensors Acura specific? Others have had the same problem with the universal TPMS sensors that you can buy from places like Tire Rack or other wheel/tire distributors. You'll probably have to go to the dealer and have them programmed.
Fortunately for me I bought a set of TPMS sensors that actually came off a 2009 TSX for my new wheels. So they were already programmed to work. Swapped the wheels on and they recognized them instantly.
