FORD Maf Sensor wiring
I have a European 2000 model Ford Cougar which i do not know the model in the US, it is a coupe which replaced the Probe from 1998 onward. The MAF Sensor has 6 wires which when tested, 4 seems to be negative as i am trying to place a 15 ohm resistor on the neg wire.

RE: FORD Maf Sensor wiring
Click my Autoshop tutorials link and look for "air flow" sensors. That should tell you how it works and help with the wiring.

You could also click my Documents link and at the bottom is a sensor request form, but I'm not sure if it covers non-US vehicles.

I have a Ford C-Max 1.8i. I have a plan. I have a pot of 0-47 kOhm. I used the range of 5kOhm to 40kOhm while driving. Now I am at 10kOhm with 450 mVolt O2 correction. My results are now 20% less of consumentation or 28 to 36 MPG.

Hi Martin, thanks for those photos. Is 450mv not extremely high ? last time when i adjusted my EFIE to 420mv, the engine was pinking and drove for 2 minutes and the engine virtually cut out. Sorry i do not understand what is consumentation ? Guessing as what you stated on the last part, your fuel economy has worsen ?
Thanks
Mike

RE: FORD Maf Sensor wiring
I am using 470mV boost on my O2. The engine starts dying a 475mv.. Still no savings though.

I thought the fords were frequency based MAFs ?

Hi Mike
Sorry I didn't look with the translation tool if all is right. I mean 20% less of liter each 100 km.

Yes 450mV only work at me, while I have in my washer bubbler gasoline instead of water. This cold vapor should give less of need gasoline by the injection.
But I started last saturday with this new idea.
