Title: Omega 2.6 2002 Auto Maf meter need help testing
Post by: Andy A on 11 May 2015, 20:59:40
Is there any way to test a MAF meter with a multimeter to see if its faulty or good?

Thanks

Unplug it and see if car runs any better  :y

If so you need a new Maf..

Any Codes ?

No codes, but the idle feels slightly lumpy although the rpms are fairly stable. I can feel vibration on tick over inside the car. I owned a 2.5 before and that engine was silky smooth and quite inside the car. But this 2.6 is not. Unless this is normal.

I'll unplug it and see if it makes any difference.

Thanks

Dbw cars are by their very nature a touch lumpy :y caused by the ecu constantly tweaking the air/fuel ratio...

There's no real way, apart from a continuity test, the changes in pd across the wire is minimal as a stand alone sensor.

I read this morning that if the multimeter has a Hz frequency test on it it can be checked by this method. I'm looking into that at the moment. Unfortunately my multimeter does not do frequency testing.
