I have a check engine light code 36. I can't find any info on the air switch solenoid circuit. I don't even know what one looks like! It starts and runs perfectly it drives great till it warms up then it seems to lose power when I hit 55 mph. I am stumped on what it is and would like to change that part to see if that's it. But first I have to know what that part is. Any help would be greatly appreciated.

 

Thats a new one to me. Was this using the key-on/off technique or a scan tool?

Info on your jeep would help too. What engine are you working with?
