On your SN95-model 5.0 TPS, the
first grey wire is the
ground, the
second grey wire (with the white stripe) is the
test wire and the
brown wire is the
5v source.
So, to test your new TPS you would put the
negative lead on your voltmeter to a good engine ground -
or the first grey wire. Then you would put the
positive voltmeter lead to the
middle grey (with white stripe) wire.
You already know that you should be reading around .98-.99 volts and that you should be taking your reading with the engine off, ignition on, right?
