Audi AAN 5cyl 20VT engine
Please use the 5 pin Mass Air Flow Sensor plug (car is a 1993 Audi S4 AAN 20VT) for WB02 sensor on oID=1591 (?) VEMS Motoronic55 ECU.
Please measure the MAF pins in the harness
- which AANpin it belongs to (fill in table below)
- any pin connected to ground must be avoided.
- Is there a +12V pin (capable of 2..3A) for heater+ ?
Can you fill this in ?
MAFpin, pin on the 55pin connector, function :
- 1, AANpin... ,
- 2, AANpin... ,
- 3, AANpin... ,
- 4, AANpin... ,
- 5, AANpin... ,
- 6, isn't it a 6pin connector ?
Do you have a male plug (maybe ripped from a bad MAF) ? Unfortunately we do not.
In the meantime, review VemsAudiAan
You can do the verification measurements,
