So I went to get emissions done and my fuel system and egr system weren't ready. I hadn't cleared any codes or unplugged the battery for months so they should have definitely been ready by now as I daily drive it. Haven't gotten any codes either. I am tuned and my mods are down below. Any ideas as to why they aren't going ready?
Mods:
Texas Speed 1 7/8 headers with cats. No rear o2 sensors and are deleted in tune.
Ported IM/TB
Rotofab CAI
Do the rear o2 sensors come up with permanent codes that don't trigger a light because they are turned off?
These cars don't have EGR's, so not sure about that one.
No codes at all when I scan with hptuners. All the rear o2 sensors codes are set to No Error Reported and the SES Enable is unchecked.Quote:

Did you put the rear o2 back into exhaust or just leave them hanging?
does any one know what it takes for the fuel system readiness to go ready?
I have fuel system, o2 sensor and egr not set. I have LTH but all the pertinent DTC set to no error reports, and left the SES checked. Gen V 2018 silverado.
Not sure why EGR is not ready as we dont even have one? Need to get at least 2 of those monitors ready to inspection.
I keep getting a check engine light ever couple days now after headers.

I have them SES unchecked and set to No report but I keep getting a light coming on. What am I doing wrong. Do they also need to be turn off in the tune too. Not just under diagnostic
you are missing alot of DTC's there if u dont want CEL with LTH

I am having the same problem on a 6th Gen Camaro right now. P0036 P0037 P0056 P0057 even though they are disabled in tune.
I went back to those 4 and checked the SES box but left them NO report. Haven't had a problem since but it's only been a week. I found an older thread that gave that suggestion.
Thanks for the reply
