So my P18C2 "permanent" code is gone. As I had researched on the internet the error code on newer OBD2 goes "permanent" after you repair. Once the ecu sees the repair and monitors 3 fault free cycles or 1 fault free cycle after a scan tool clear DTC request, the permanent DTC will be erased. I am still amazed my GM dealer didn't know this. Caused me a lot of grief. Now back to our regular schedule of cruising and car shows.
