TPS adjustment question
Well I got the rest lights in today that I bought, and went to adjust my TPS. It says to turn the adj. screw until only 1 light is on, but when I was turning it, only 1 light was on for about 80% of the time, no matter how much I screwed. Then I remembered reading somewhere that you need to bride a conneter somewhere to ground the ECU or something. Just wondered where that thing was that I need to bridge, and if that is the reason that I am seeing 1 light most of the time. Thanks
There is a green connector on the driver side fender near the battery. It has two pins that will need to be jumpered together. Not sure if that is the reason you have one light 80% of the time, though.

There is no requirement for the initial set coupler to be jumpered. If your using the two light method, with the two bug light unit plugged into the green connector, try this to make your life easier:
Fully warm the engine up(hot, not tepid warm). Shut the engine down. Key to the on position. Turn the tps screw counterclockwise until both the lights go out, and for extra measure turn it some more counterclockwise but make sure the thing does not unscrew and fall out.
Now turn the screw clockwise until you see one light, keep turning more until you see two lights and stop.
Now with two lights turned on, turn counterclockwise, slowly, until you have only one light on.
Your done now. Through. Done. FInished.
Don't EVER set your tps with a less than fully hot engine.
Now if you had a volt/ohm meter, you could shove that meters positive probe up the rear of the green/red wire at the true tps connector while everthing is connected, and you'll see an output of approx one volt. Something on the order of 0.95volts or 0.97 volts or 1.04 is what you can call *approx* one volt.
Also if using the bug lite method, do not try adjusting the tps with the engine running.

I defer to Hailers. My apologies...my confusion.

EDIT: What's worse is I just did all of this a couple of days ago. I will go back to sleep at my desk now.

It does not hurt to jumper the initial set jumper, but then again it does not help either. Its a wash. Back to sleep at the desk now. The weekends coming up and you need all your energy for that.
