bank one emissions would be an O2 sensor, the thing on your throttle body is a MAP sensor (manifold absolute pressure sensor) and that measure the amount of pressure coming into the manifold, really the decreasin amount of vaccum and comes up with a fuel mixture amount to deliver to the engine.

i really dont like the OBDII code scanners aut parts stores use, i havent had much luck with them, the honda unit is far more accurate in delivering CEL codes
