I have been troubleshooting an IAC P0507 circuit problem. I think things are now working OK but want to verify by reading the IAC count (position). Has anybody been able to get a reading using the GM enhancements for the Torque app? Mine is constantly reading "0" but the actual RPMs seem to be matching the "Desired Idle Speed" fairly closely under many operating conditions.

 

Is anybody using the Torque smartphone app?

 

Never mind. Using the PID definition in Torque, I transferred the PID parameters into a laptop OBD program, Touchscan. Fiddling around a bit, it is now working. It is idling when warm around 20 counts and was as high as 120 when cold starting in 30 deg weather.
