I need to know which colors to tap into so I can install my tps voltage WOT switch and an air/fuel guage.

Thanks

 

ttt anyone know which wires are the output wires for the throttle position sensor or o2 sensor?

And by chance does anyone know the voltage of the tps when at WOT ? my NX activation switch needs 4 + volts

 

For a 2000, looking at the schematic, I believe its Dark blue for the sensor signal, grey for the TP sensor 5V and black for ground.

YMMV

 

Blue wire on TPS. Use a small sewing needle to pierce the insulation on the blue wire. Attach an alligator to the needle and the lead on your DVOM. I think the voltage is just over 5 VDC at WOT. You can look in the shop manual to be sure of the WOT and closed throttle values.

My voltmeter turded out........so I called the dealer and one of the techs looked it up.........but he said there were 2 sensors, 3 wires each, and that the grey and light blue were the 5V wires, but one side was from low to high and the other from high to low.........I guess meaning that one reads 5V at WOT and the other at closed throttle. So..........any more info? He also said that the bank1 o2 sensor signal wire was purple/white

this is drive by wire too.......just FYI

 

ttt - before I make this last connection, anyone have a manual for a 03 drive by wire so I can make sure I'm splicing into the right one? My guess is the blue right out of the throttle body harness, would just like to be sure. Thanks

 

It's the Dark Green wire in position "G".

 

speartech, is this for a 2003 drive by wire tps ?

 

Yes, with the single 8-way connector on the side of the TB. Position G is TPS #1 signal.
