Technical What do these fault codes mean

[CuriousHugo]

2008 Doblo 1.3. Fault codes PO100 and PO110 showing (mass air flow meter). New Bosch MAF sensor fitted but codes still there. Engine management light was on but cleared.with code reader. No longer lit. Did notice a bit of scuffing to the wiring loom underneath the MAF sensor near to where the MAF sensor joins the loom which exposes a bit of the wiring. Is it possible that the exposed wiring is faulty and causing the limp mode ?. Everything else changed EGR, full exhaust with DPF, catalytic convertor, wastegate, battery, flow plugs, cam chain, you name it, it's all new. Any help to get her running properly again would be great. Thanks. Mark.
