MAF setting Questions

You should not put it into the cable, but test at the MAF's connectors itself...

BTW, I had again to move up a few ohms... Now at 510 ohms

sorry, i was thiÃ…â€žking MAF connector
in the first and last?

first and last is correct...

OK, here are my ongoings on this topic again....

Had a valve-cleaning additive put into the fuel... Now my MAF works as it should at ~400 Ohms

what kind of cleaner did you use, which brand ?

Hey there...

I think it was LiquiMoli or something... I have to look at the shelf in the shop again

It WAS LM Valve cleaning fluid....

Today I tried setting the MAF using this procedure. Tried before but the LED stayed off all the time. But, lambdasensor was broken so after replacing that I had to give it another try.

From 200ohm to almost 900ohm the LED is off. Tried with a multimeter and it reads 0,99V between the battery positive and the testpoint. It never changes, no matter what the MAF is set at. Also when I disconnect the MAF (the mixture should go rich like said in this topic before) nothing happens.

I like to set my MAF at some good value. When I first measured it, it was set at 106ohm by the previous owner. Increasing this to 382ohm made idle smoother and the engine running better. The lumpy feeling when idling had become much less, but it isn't fully away jet. So I guess the MAF should be somewhat higher, but I can't measure when it is set correctly. Maybe I should just try some values...?

My car is a '89 turbo. For some reason I don't have a grey loom like in the picture on page one. My loom is black. Maybe that is the reason it doesn't work

Okay, Mr Novice here!

Can someone kindly give me 'idiots-guide' style

instructions on how to set the MAF.

I have a multi-tester & know about the adjusting screw on the MAF. What I do not know is which pins to connect the tester to. I did try following instructions given previously but failed to get anything other than 0.004 as a reading

Obviously I was gertting something wrong.

My mleage is at 27.2 & reckon iy should be a little higher?

Thanks in advance.

I'm sorry guys, been doing the search but nothing came up. Can i adjust the resistance in the ES model or only turbo's??
Does the ES (1.7) has the wires to connect the led as well?
Mine is an 1990 ES with cat. and lambda sond.

Best regards

Help please, i can't seem to find those wires on the ES.
The diagnostic center gives me the error 2-1-2 (oxygen sensor, no signal or faulty). I found a connector with 6 wires that seems to come from the oxygen sensor but donÃ‚Â´t know were to measure voltage, which are the wires?

Thanks

Can't really help your questions GTImk1, due to me being a complete novice!

For all its worth, mine is a 91' Turbo. I reset my MAF on Sunday. Used a multi tester. Engine running and well warmed up, unplugged the connector on the MAF then connected tester to the first & last terminal on the MAF. Then turned the screw till the tester showed 382 Ohms, which I beleive is 'the norm'.

Mine was down at 280 odd, so I'm hoping for improvement in performance - early days yet.

I worked this 'method' out from my understanding of this thread - not sure if I've done it right or not.

Also I may be wrong but I think MAF sensors are specific to Turbo models - but stand to be corrected. No doubt, on here someone will confirm either way.

As for that wire mentioned earlier in this thread to put an LED tester on, I cannot find it on mine for love nor money? Mind you I have'nt got an LED tester & don't really know what one is either

Thanks to all for the posts on this one so far.
