I have had both of mine disconnected, from time to time. *I* have never seen any codes as a result.

RACE ON!!!

The egr will throw a code (along with making your combustion temps go up). There shouldn't be any codes for the air pump, but without a heated O2, you might not see closed loop operation at idle.

On MY car, the EGR is solenoid activated. If the solenoid is left connected and merely the vacuum hose blocked or removed, the ECM doesn't know the difference, hence, no codes.

RACE ON!!!
