MAF sensor

Hi it appears from the responses i had that my Alfa GTV 3.O could have a MAF sensor problem. Thanks for the reponses. Can anyone let me know where it is. I want to disconnect it to see if this is the problem.

Does anyone have any pictures where it is situated.

Re: MAF sensor

To the right of the engine.. black tubey bit.. in the middle of black tubey bit is a thingymejig with a pluggy thing in the side.. that's the MAF

I could get more technical but not sure it needs it

Re: MAF sensor

you could try giving it a clean...worked for me...

Remove the MAF - undo the metal clips with a pair of small pliers or lever off with small screwdriver, undo the cable tie which keeps the connector cable tidy to the air duct.and then the connector remove the MAF.

There are 2 TX secrurits screws that clamps the sensor to the MAF body...these can be undone with pliers as they are not to tight.

Pull the sensor head out and stick the MAF body a bowl of luke warm water and slosh about...use a sponge to clean the inside of the MAF body but do not touch the Mesh. then put back in the bowl and leave for about 20 Mins...

To clean the sensor head you need anti-static cleaner from Maplin or any radio hobby store..

Spray liberally all over the head......

You will see a channel in the sensor head, and will notice a wire running can clean this with a cotton swab with cleaner applied.....don't go to mad just apply gentle pressure.

At the side of the sensor is a metal plate within another can clean this using the cleaner and some tissue, wedge it in the grove and slide in and can use a small screwdriver to exert more pressure to clean the plate and the edges.

The sensor heads..electonics is sealed so don’t worry too much...but still be careful.

When this is done....rinse the sensor head under luke warm running water from the tap and just cover the top part of the head where you have cleaned...

when done remove the MAF body that was soaking, test the mesh for cleanness with a cotton swab, if still dirty use the anti-static cleaner to clean more..and re wash in luke warm water.

Lay both the sensor and the MAF body...on a tea towel on a radiator to dry ...

Re-Fit the MAF all back together and put back on the car.

Re: MAF sensor

Did anyone Try MikeBrowns technique. I'm pretty sure mine is playing up but heard of bad results after a clean.

Re: MAF sensor

wow - theres that tutorial I wanted, I have my light go on and off ever time I bring my GTV over 100mph in 4th gear, it drives slower when the lights on and then after a few drives reverts to normal again, I just keep the car at 80mph - but its soooo hard on motorways when they are empty.
