Hi, this is Bo, an auto expert on RepairPal's Car Genius team! The P006C and P0627 codes you're seeing point to issues related to the mass air flow sensor (P006C) and fuel pump control (P0627). Even though your fuel pump was replaced a couple of years ago, the P0627 code suggests there may still be a problem with the fuel pump relay or its wiring, or possibly the fuel pump itself. As for the P006C, it's often tied to a performance issue with the air intake system, such as a faulty MAF sensor or a vacuum leak. Start by checking the fuel pump relay and fuse, then test the wiring for continuity. For the P006C, inspect the MAF sensor and clean it if necessary. If these don't solve the issue, the fuel pump or MAF sensor might need further inspection or replacement.
