Citroen C3 1.4 HDI Limp Mode

[sebbonit]

Hello everyone,

After trying to fix my mom's Citroen myself and failed you are my last chance.
Mom's Citroen goes into limp mode at higher revs and (sometimes) beeps 3 times while going into limp, after inspecting under the bonnet I've found out that the maf sensor plug was damaged so I've rewired new plug using this schematic and changed the maf for a new one.

but the problem still exists, I've scanned DTC codes using obd and those are the errors that i've got

P0102 - MAF sensor/volume air flow (VAF) sensor low input
P1163
P0002
P1351

I'd be very grateful for any help

Are you getting a reading off the MAF in live data?

no reading, checked all the connections to the ECU and one from pin 4 to the 16way connector in the engine bay fuse box and all of them seem to have a continuity
