After cleaning my S49 2.0T MAF I'm testing the MAF voltage with a multi-tester. What should the MAF range of output voltage be say at ambient temp at idling and opening the throttle. The red wire when earthed to the negative of the battery gives input voltage of +12V (in fact +14V probable due to alternator charging my battery).
