Two generic questions.
1. How to ?correctly? turn-off something. IE rear 02 sensors -GM based engines.
2. How to Reset the PCM (and not needing to drive it 50 miles to get the computer to not show INCOMPLETE on the DTC section) -again GM based
For sensors (O2) I have read several different threads/posts and seem there are a few ways people have found to do the above. I have read that in some instances if you have to do emissions testing, their scanner will detect if items are turned off, but yet others so their emissions scanners can?t tell this.
I have read to turn off items with the drop down, and select No Error Report, as to where I have seen others say to enable temperature threshold to not use the rear o2s, and yet others say to turn off the rear sensors through the airflow section.
any and all comments fully welcomed.
