I am trying to remove the check engine light for rear o2 sensors from a 12 tundra that has had the cats deleted. I can get the light to go out on the dash but the code is still there when you scan the obd2 port. Under the Engine Diagnostics tab I have the check boxes for both MIL Enable and Emission unchecked and i've tried MIL 1st and 2nd on the right column. Anyone know what the difference with MIL Enable vs Emissions is? I'm used to chevy stuff where you uncheck the boxes and the code goes away completely, is this different or is something else going on here? I'm concerned that leaving the codes for the rear o2 sensors registering in the pcm will cause an issue.
Here's the file 12 tundra modified no rear o2 sensors.hpt
