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 ?
