get a multimeter and check the faq, theres the specs in there for the tps. you just measure the resistance between each terminal and make sure its within spec, if not you adjust it.
i tried adjusting the tps and its no good, specs dnt match up, like between the blue and the red wire it should be <2.3ohms and it wnt go over 1.5ish, if i move it around itll go up to 1.5ish then drop dwn to nothing or ifinity...... faulty tps?
