So I have this 2006 truck that when cruising down the highway it will come out of closed loop and revert to 16.0 commanded AF as well as sometimes 13.6 AF. When I was in SD it did not do it. If I floor it it will go to commanded 12.8 then back to CL for a second (trims working) then right back to 16.0 (or 13.6)
If I come to a stop it comes out of it and goes back to normal CL operation. What am I missing?
Shows in the log around 3:30 I believe
Thanks
Sounds like a catalyst test... Try disabling the test and driving to see if it still does it...

Sadly there is no cat test to disable on those computers, been in this same boat already with a 2006 computer.
If you are not running cat converters, you need to re-install the rear o2 sensors and along with disabling the code. That was the only way to stop the cat test from happening. I just zip tied the sensors to the frame and all was good.

Your right - I didn't look at the tuneI go here when I have a vehicle that I can't modify the tune on if it's had the cats removed - http://bigdaddiesgarage.com/
They work good and keep the cel off... Of course without killing the codes it would still run the cat test...

So just plug the sensors in and leave the codes turned off?Originally Posted by 5FDP
Yes, plug them in and tie them up somewhere and set the codes to 3 no error reported and the cat test will stop happening.
