Fiesta 1.25 MAF sensor?

coxmattycox · 2 Jan 2013 at 23:17

Hi,

I am looking into a increase in petrol consumption and slight hesitance at time in acceleration in my 51 reg fiesta.

I know were the lambda sensor is, but I have also read to check the MAS/MAF, Mass airflow sensor? I've had a look in the Haynes manual and cannot seem to find anything relating to it,

Does anyone know if it has one and if so were it is?

Thanks

It'll be in the air intake somewhere, probably in the pipe work between the filter and the inlet manifold

Good luck, I couldn't find it on mine. I think I ended up cleaning the intake temp sensor, or it might be the maf. The only sensor I could find was buried under the inlet manifold.

Pretty certain

Different spec, but I can see were it is on mine now thanks, I will have a play to see how easy it is to get of.

Thanks

Make sure you use the right type of cleaner on it. Or it can wreck it, they're apparently quite sensitive

There's video's on youtube showing you how to clean them.

What year 1.25 is that? Looks nothing like how mine did.

That looks more like a 1.7 Puma engine. Does your have the plastic airbox on top of the engine? If so you'll have a MAP (manifold pressure sensor) based system not a MAF. *edit looking at the year of your car you will almost certainly won't have a MAF.

Later engine:

Earlier pre 2001 (?)

Just unplug the MAF first and see if the hesitation goes away, if it does your MAF is probably faulty.

it would be around a year 2000 model, looks exactly the same as my friend's y reg mk4 1.25.

Without a photo of the actual car it's kinda hard to help totally accurately.
