setting the TPS

[creighta]

Looks like this is the project of the month. Damn limp mode! Mine has been behaving after a rear speed sensor, but still shifts hard. I see that the TPS should be at .92 or so at idle, but how do you check this?

Where do you put the meter leads? Was going to swap mine this weekend but maybe I just need to set it.

Get a multimeter and put the red lead on the middle wire on the TPS connector (might need to slip a paperclip in there if your probes aren't sharp). Put the black lead on the neg side of the battery or a good ground. With an already warm engine (fast idle solenoid off) turn your ignition key to on (just shy of start) and keep it there. Now loosen and adjust your TPS (two torqs screws) and adjust for .92 - .94 or so at idle. Tighten the screws. Now slowly actuate the throttle and look for smooth increase in voltage, up to about 3.8 to 4 or so is normal. If the voltage jumps around or there is any dead spots, replace your TPS. Napa has them pretty cheap.

I think my price was $12. I just thought i better check it before I replace it.

Thanks for the info.
