Sorry Rob! That would be FSM(Factory Service Manual) as I got a bit carried away with the abbreviations.
Looks like the aacv is under the collector to the driver's side of the car. You can see a hose coming off the TB running around the outside under the collector, and into the front of it with another coming off the rear of it and into the air plenum. There's a power lead on the front as well. Actually looks like the bacsv would be easier to access, and none of the troubleshooting steps take the aacv into consideration. Trouble code 24 has the tech testing(ignition ON) battery to the ECU(pin 14 conn B62 to body 10V ,min) harness connection between the ECU and main relay(resistance;pin 14 conn B62 to pin 4 conn B52; 0 ohms), power to main relay(pins 1&2 conn B52 to body 10V, min), input signal from bacsv to ECU(pins 1&2 conn B62 to body, 2=7V; 1=6V, min) and finally harness connector to the bacsv(resistance, pins 1&2 conn B62 to pins 1&3 conn E15 of 0 ohms) Am I just confusing the issue?
