If you have a 2013 I don't believe it has sensors. It uses some algorithm based on tire rotation.
When you set all the tires to 32 psi did you press and hold the TPMS button?
What year/trim is the vehicle? Did you check for any TSB's that reference the problem?
Search this site, see if there's any similar problems that might have a solution.
I take it you did not buy the vehicle from a Mazda dealer.
Consider yourself lucky. Also Acura has timing belts instead of chains. That's a major cost. I also replaced one of those at around 80k. Hopefully the new models now have chains.
