I've been trying to get my AEM UEGO wideband to read from the a/c pressure voltage PID.7101. I've added the AC Pressure PID to my table, but am not getting any voltage reading through HPT. I'm using pin 45 of the blue PCM connector on my 04 GTO PCM. I've tested the white output wire from the WB all the way to the PCM pin and get a voltage reading, but nothing on HPT.
is there something that needs to be enabled for the AC PID to be read?
below are my config and log files.
if any one can see something wrong with my setup, please let me know.
Pin 45 on the blue connector is the 5v reference out to the pressure sensor. Try pin 14 on the C2 (is it green on the GTO?) connector, which is the input from the sensor. Hopefully you have not burned up the AEM output by putting 5v into it.
The 2004 GTO A/C pinout seems to be the same as the 2002 Camaro.
