Also, I know I'll need a multimeter, so, where and how!

 

Ya I want to know how to do this ish also.

 

It is very easy to test the MAFS all you need is a voltmeter or multimeter to check the voltage while engine is off and key is at "ON" position. You'll need to backprobe terminal one (left most connector) on the plug. It should be less than 1.0 volt. With the engine idling at operating temp is should be 1.0-1.7 volts. With the engine running at ~2,500rpm it should be 1.5-2.1 volts. You should observe a linear voltage rise in response to increses in engine rpm up to about 4k. If voltage is within spec you can also check the power and ground circuits.
