If your state requires inspection you wont pass. You would probably throw a P code and keep the system in open loop.

rockfangd Posted June 28, 2019 Report Share Posted June 28, 2019 Really it is not possible unless you can rewrite the computer to not look for it. It is always looking for the proper variable resistance feedback for every component it is testing. The conditions are never the same. there are too many factors. Ambient temp fuel level, and many others GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
