Pretty sure I can see the AC pressure sensor right beside the compressor, but i'd like to know if anyone has used the egr solenoid/valve Pid? Does the balty even have an egr Pid?

I've got a 2007 2.4l auto, my egr solenoid (at least thats what I think it is...) only has 2 wires...tested both for voltages today and they showed over 12, so that isnt within the 0-5v range.

AC?

 

1. What're you looking to tap into for voltage?

2. Cobalts do not have EGR.

3. Don't tap into the a/c pressure sensor. That only has 5 volts going to it for signal reference.

 

Yup, that is perfect for logging WB via HPTuners for those of us who bought the cheap version...word to wise: spend the extra $150 and get the upgrade so you dont have to hack into oem Pids.!
