-

Check mass of air drawn in in display zone 4 
Specification: 2.0 to 5.0 g/s

-

If value is as specified but DTC memory has recorded a DTC relating to Mass Air Flow (MAF) sensor, check voltage supply for Mass Air Flow
(MAF) sensor.

If the specification is not obtained:

-

Check signal and Ground wires of Mass Air Flow (MAF) sensor.

If the specification is attained:

-

Press -> button.

-

Press buttons 0 and 6 for function "End output" and confirm entry with Q button.

-

Switch ignition off.

Testing power supply to Mass Air Flow (MAF) sensor

-

Disconnect 5 pin connector oft Mass Air Flow (MAF) sensor (G70) -arrow-.

-

Connect multimeter to measure voltage on connector terminal 2 and engine Ground.

-

Start engine and run at idle speed. 
Specification: 11.0-15.0 V

If no voltage is present:

-

Switch ignition off.

-

Check wiring between terminal 2 and fuel pump relay (J17) using wiring diagram.
