Thanks for this tip, i wanted to do this but didnt have the special bits to remove the sensor, now can just remove the whole thing and clean it up.

Don't they do this as part of regular service in A.S.S ?
I have never seen this as a seprate item in any of the bill. But like oil change, oil filter etc. if this is part of standard service activity.

Thanks for posting with all the snaps, it really helps.

As per manufacturers, this is not a servicable part and requires no cleaning. But "WE" think otherwise.

Does anyone have an idea about where exactly is the MAF sensor located in the Lancer, and how to get to it? I'm convinced that my car's really needs cleaning.

It should be inline with the airhose or near the air filter box. Have you checked ?

the lancer doesnt have a MAF if memory serves me right,its the cedia and the evo and the other likes from mitsubishi that have them,hope this helps,cheers,happy revving..!

Does the Indigo have a MAF and if yes, does the 10000Km deadline mentioned earlier hold good for cleaning it as well?

To add to what ajmat suggested, the MAF can look different on different vehicles as what Ajmat has cleaned is actually a SiMAF (Integrated Mass Airflow Sensor) which is the sensor and its mounting assembly. The sensor looks like this :

Attachment 416539

Behind the white shield are 2 filament wires and air flows thorough it for the sensor to detect. You should never touch these as that can damage the gap between them, not to say the sensor itself.

I would say that they do not require cleaning very often, the last time I checked in my Safari at around 30K, the wires were still shining with very little carbon on them.

You can even use a MAF cleaner or for that matter any electrical cleaner spray (like used by mobile shops). But don't clean it if its not required.

I think this a a pressure and temperature sensor, rather than a MAF sensor. There should be some kind of tube in a MAF which contains the flow and measures it. Basically the sensor is a tube + some wires inside the tube, you cannot separate those 2.

I might be wrong though.

The picture looks like a BOSCH pressure and temperature sensor. The mass airflow is calculated with the pressure and temperature and knowing the volume of the chamber in which it is connected.

Nice useful thread. Thanks ajmat.
I think this would help me and if I try out,will post more pix.

Yes, your judgement is wrong here.This is the SiMAF, the tube is on the other side.

By the way IPA is the perfect way to wipe down a car after a proper wash. It dries up the car and removes the static charge.

I see your location is Bangalore can you please tell where exactly one can purchased Iso-Propyl alcohol ? I tried at several Chemist shops but they stock only Methylated Spirit ( Ethyl Alcohol + methanol to poison it)

Does Esteem MPFI, 2007 model, has this kind of sensor? Asking cause I've never noticed any component like this around the air filter housing.

you could also get the electric contact spray, I have done alcohol and found the spray more user friendly. I picked one up from the skoda service center made by Wurth.

For using electronic contact spray the MAF housing needs to be opened ( In my vehicle it looks like the pic Dadu has posted) dipping in IPA in zip pouch is more user-friendly besides that IPA has many other uses also.

Cash Pharmacy or any hospital chemist. In Cash Pharmacy when you ask for IPA they ask you how many litres do you need.
