Hi

This wee car keeps brining up a mass air flow circut low input fault, it's had a new genuine maf sensor. Read live data for air flow and it reads 0 kgh when car running. Can anybody help me with the wiring from maf to ecu. Autodata doesn't list much for engine system..4 wires I have at sensor are brown. Blue/ white, red and red/ blue

Thanks in advance Alan
