Maf is it analogue or digital
#1
Does anyone know if the maf is analogue or digital? Pinnouts? 

I have pin 1 green - 5v 
2 yellow - ground 
3 unused 
4 red + 12v
5 blue- I was getting 12v to ground on this! 
6 unused

Well i found this if anyone requires further info

Vehicles: CITROEN, FORD, PEUGEOT Product: Air mass sensor Models with 1.6 l diesel engine PIERBURG No. Replacement for O.E. No.* CITROEN Berlingo, C2, C3, C4, C5, Jumpy, Xsara Picasso (HDi) FORD Fiesta, Focus, Fusion (TDCi) PEUGEOT Expert, Partner, 1007, 206, 207, 307, 308, 407 (HDi) 7.28342.06.0 7.28342.04.0 9650010780; 1232096; 1255117; 3M5A12B579BA; 3M5A12B579BB; Y60113215; 1920GV; 30774680

Its digital with temp sensor built in too.

1 Temperature resistance 2 Earth 3 (Not assigned) 4 Supply voltage (12 V) 5 Frequency output

Testing the supply voltage Equipment: Oscilloscope or corresponding function on an engine tester or multimeter • Disconnect the plug from the air mass sensor. • Connect multimeter or oscilloscope to pin 4 and pin 2 of the connecting cable ("Volt" measuring range). • Turn on the ignition. Setpoint value: On-board voltage (> 11 V) Testing the temperature sensor Equipment: Multimeter or engine tester, thermometer, suitable equipment for generating heat, e.g. hot air gun. • Use a motor tester to test the actual intake air temperature values stored in the engine control unit. Setpoint value: Ambient air temperature Alternatively: • Disconnect the plug from the air mass sensor. • Connect the multimeter to pin 1 and earth (2) on the air mass sensor (“Resistance” measuring range). • Use a hot air gun and the thermometer to set various testing points. Examples: °C 0 25 40 60 120 Ω 5846 2000 1128 564 103 Testing the air mass flow rate Equipment: Oscilloscope or corresponding function on an engine tester • Air mass sensor can remain installed. Plug must remain connected. As no method available in the workshop for determining the actual air mass passing through as a reference, the measured value with the engine stopped, i.e. air mass = 0, is used as a reference variable. • Turn on the ignition. Do not start the engine. • Measure the frequency between pin 2 and pin 5. Setpoint value: 5000 ±10 Hz • The signal voltage from the sensor must be around 12 V. In the oscilloscope image, this is the highest value of the rectangular signal. • Start the engine. • Press the gas pedal. • The frequency must now fall, i.e. the curve in the oscilloscope is extended further
