The 3-pin connector on the TPS
Black=GND
Orange=5V Reference
Green=TPS Signal return

Find 2 sewing needles and back probe the BK & G wires with the TPS connector attached to the engine harness. Loosen the TPS bolts and with your multimeter on Volts DC, measure the voltage and keep rotating the TPS until you get a reading of "1V" to get it back in range. The TPS is factory set meaning it is non-adjustable. Now you have to adjust it yourself because the TPS was not intended to be replaced without the TB as a whole.

 

You shouldn't need sewing needles. Most multimeter needles fit in enough to back probe.

 

What kind of multimeter probes do you use? Stretching out the rubber insert with anything bigger than a needle might give you mixed results, if water gets trapped inside, corroding the terminals down the road.



The reason why the TPS starts the reading at 1V is for fault checking, such as the code you received.

 

You said you replaced the TPS on the 5.0's & 5.8's you have to be carefull and not rotate it counter clockwise when you install it or you'll get a high idle.

 

thanks everyone! I just had the TPS installed bass- ackwards

runs great now!
