Measure the resistance across the Fuel Shut off Switch (Pins 39 and 36). Move the AFM flap and ensure the resistance is infinite when the flap is closed and quickly changes to 0 ohms when the flap starts to open.
Measure the resistance from the high side to the low side of the pot/copper trace. (Pins 8 and 6). It should read ~180ohm
Measure the resistance across the "standard"/"Reference"/"Control" resistor. (Pins 8 and 9). It should read 100ohms
Measure the resistance across pins 7 and 8 while moving the flap. It should change. (though it may be jumpy)
Repeat this but between pins 6 and 7 while moving the flap.
Measure the resistance of the thermal sensor. It should read 2500ohms +/-250ohms@ 68°C
