Conner,

I finally had a chance to get back to checking this thing out and I am still a little baffled...

My results are in red below.

Here is how i would test the TPS. Disconnect the connector at the TPS and measure voltage on the harness side with key on.
Y/R wire-------12 volts [color:"red"] 4.67 [/color]
G/B wire-------Ground [color:"red"] Good [/color]
G/Y wire-------5 volts [color:"red"] Good [/color]
Plug connector back on and read voltages
Y/R wire-------Throttle closed----0 volts [color:"red"] Good [/color]
Throttle opened----12 volts [color:"red"] 4.67 [/color]
G/W wire-------Throttle closed----.05 to .08 volts [color:"red"] .687[/color]
Voltage should increase smoothly as throttle is opened to full position. [color:"red"]Good[/color]
If the first set of tests are good and one of the second set of tests fail, the TPS is bad.

You mentioned in the post above that the FSM shows anything over 4 volts is good on the Y/R wire.
So I am unsure if the test failed, the numbers for the Y/R wire test matched the top proving the switch opens without much resistance, but the numbers definitly were not in range on the last test of the G/W wire they started at .687, no mater what movement of the TPS (clocking it), and ramped up to around 4.9x volts, the ramp is smooth but not sure it the numbers being off are that bad???

Also when clocking it it is a pain in the <img src="/forums/images/graemlins/butwiggle.gif" alt="" /> to get it calibrated, the thing jumps around like crazy... Are these signs of a dead TPS?
