Pretty sure those are all smog related, dealing with what you removed. Did you remove the egr as well? Cause I think that first code is a bad a egr sensor otherwise.

81, 82 and 84 are for the three solenoids behind the RH side strut tower being disconnected/missing.

85 is for the CANister Purge solenoid being disconnected/removed.

31 is for the EGR sensor being disconnected/removed.

In your setup, it's the equivalent of a "system pass".

111 - no fault codes registered for that self test routine.

165 - no clue, it doesn't show as a valid KOEO or KOER self test code

536 - Brake On/Off circuit failure / switch not actuated during KOER test

If the fault code was logged during a KOER, it means you forgot to press the brake pedal after the engine ID code was displayed (4 = 8 cylinders engine), not that the switch was at fault...... LUK.
