Technical Help with a maf sensor

[Bemylover]

Hey. I have a one question from you guys. I have to change my maf sensor (fiat doblo 1.9jtd 74kw 2002) but I'm not sure that maf sensor of my car is with original number.
I'm try several used maf sensor but none of them are not working. So I am thinking , maybe is previous owner change maf sensor from another car.
Maf on my cars Is currently is this (on picture)
How and where I can Check original sensor for my car?

Easiest way is to put your registration number into Halfords or euros and see what comes up for that engine. Each manufacturer will have a variation on parts but it should give you a reference point.

Google F00c2g2044

Maybe fault is not the sensor?

This is log from 4th gear and full throttle from 1500rpm to ~4200rpm.

Check for leaks in the pipes between the maf sensor and engine

Does the car drive normally?

If you disconnect the maf and drive - does it drive better?

 

[jackwhoo]

Use eper to find the fiat part number then Google the fiat number-look at images-I think you will find part number may be correct

I checked every pipes, and it looks fine, no leaks. No, car have a less power than usuall. When I disconnected maf sensor, the car is goes even worse.

Blocked air filter? Blocked exhaust?

 

[Bemylover]

Thank you, I will try with Eper.i didn't use a Eper, when I type Vin number, It should show me the sensor with the original number?
Air filter is ok (i change it at every 10.000km)
Exhaust is ok, turbo is ok (turbo is replaced last year)

I checked every pipes, and it looks fine, no leaks.

Might be the gaskets, not the pipes. The air intake manifold's gaskets, especially the ones between manifold and Cylinder head.

Heyy, sorry for the late response.. Last year I am cleaning the intake mainflod, and put new gasket, so I am sure that no leaking there...
I want to try with a new maf, Which manufacturer should I take? In store they have Bosch, ngk and pierburg.Do I have to remove the battery terminal after replacing it?

 

[Mike1alike]

Bosch is ok, so is NGK, choose what you like between them. You do not have to remove the battery terminal to replace the sensor.

I tried new Pierburg maf (722701080) and bosch (0281002309)and nothing... With pierburg max value is 400 mg on full thortle, and with bosch is always 6000mg... So I am not sure what is problem...
