G'day guys, today i went out to do some diagnostics on my TPS, i've got the voltage between the red and black wire that goes to the throttle position sensor, i probed the wires, chucked the ignition ON, not a running engine, just ON ignition, and the voltage reading i was getting is - 4.95... no varying voltage when opening up the throttle, just a constant - 4.95... I had a spare sensor lying around, gave me the same bloody reading... Am i doing this test wrong? Or is this something to do with a computer fault...

Any information/suggestions on this would be much appreciated.

Cheers

Check voltage between the black and the other wire. I think it should be green..
The red or orange is signal voltage 5v

Cheers for that, the voltage starts from 0.8 and smoothly goes up to 3.8v, i believe this is normal? Wouldn't be causing my misfire / surging anyway.

Yea thats fine.....
