Exactly which components are you talking about? The EVAP canister, AIR pump, and the EGR are all emissions-related components.

There are no EVAP "sensors". There is a solenoid, though. DTC reporting can be turned off in a retune.

I once had some codes for mine. I replaced the solenoid and the valve. I got DTC codes for it tuned out anyway for my tune.
