zx_drift Posted July 27, 2010 Share Posted July 27, 2010 Does anyone know what voltage range and values at certain RPM the Air Flow Meter for a 280ZX-T is supposed to have? I'm checking mine and it is around 3 volts at idle, seems a little strange. It seems the range is 0-5 volts, 0 being lots of air, 5 being no air (which is backwards from every other MAF out there...) Any help would be great. Quote Link to comment Share on other sites More sharing options...

Any help would be great. 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 Quote Link to comment Share on other sites More sharing options...
