    What code reader are you using? Those are not standard error codes. Error codes should be P followed by 4 numbers....P1040. Did you repair the damaged intake boot? What are your short term fuel trims?

    I am using Autel ms906 it's a nice scanner I did replace intake boot I smoked dmtl no leaks I am guessing pump is bad. But secondary mass is my worry even after replacing with a new one it still comes back
