Hi guys,we’ve got a 2010 1.4 diesel fiesta in atm it’s got a P0101 trouble code in the PCM which relates to an air flow meter issue,the AFM is a Continental 4 wire part which I can’t seem to get any sense out of electrically,the four wires appear to be 2 x 12v,1x5v and an earth(sensor unplugged)I can’t work out wether the sensor is supposed to be analogue or digital ....has anyone got any ideas regarding this please ?

Hello Gudgeon,

I'm so sorry for the late reply and thank you for your post.

We have a case study on a similar 4 wire MAF sensor which you can find here. https://www.picoauto.com/library/case-studies/ford-ecoboost-maf-sensor

Hopefully this will help explain some of the signal are at least show you what to expect when connecting all 4 wires.

Kind regards

Ben
