Year of Manufacture *: 2004/5???
Engine Size and Code *: 2.0l turbo. Z20let

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

Looking at Vauxhall Tis,the wiring is as follows
red/blue is the 12v supply from fuel pump relay.(but originates as a red/white wire to engine harness connector.
Brown is ecu ground to pin 9 at ecu
blue/white is signal to ecu pin 6
red is supply from pin 7 of ecu.Also feeds camshaft and map sensor.

Hi

You might want to check SPS to see if there is a service upgrade for these.
