PO135 is oxygen sensor Bank1 sensor1. PO404 is EGR.
personally, I'd pull EGR off, clean pintle good with throttle body cleaner or carb cleaner, re-install, erase codes & try it for a while & see if it code(s) come back.

It is for an oil change mainly and any other service your maintenance manual suggests at the mileage interval. It needs to be reset after each oil change to be accurate.

A code P0442 most likely means one or more of the following has happened: a loose or improperly affixed gas cap; a non-conforming gas cap (i.e. not factory/original brand); a small leak/hole in a fuel vapor hose/tube; other small leak in EVAP system; faulty vent o-ring seal
The EGR Valve is located on top of the intake manifold. If you are standing in front of the car it would be on your right hand side. It is cylinder in shape and has wire harness that connects to the back of the engine!

404 is exhaust gas recirculation circuit, and 405 is exhaust gas recirculation sensor circuit low. EGR sensor or ground?
