anyone know where the throttle pos sensor is on a 93 4.3 cpi?
and gow to you check or replace it?

should be on the "throlttle body" directly on the other side of the trhottle cable/plate lingkage, on passenger side of vehicle.. U can test it with a DMM(digital multi meter)....should have 3 wires, one source voltage(5V Reference), one signal, and one ground. pos lead to signal, and neg lead to ground(small needles, like sewing pins would be best to backprobe the wires). with the vehicle off and key on, and meter hooked up, at closed throttle, should read about half a volt....move throttle plate and voltage should go up, at WOT, should be from 4.5V to 5V.

if the meter reads ~5V, make sure u are not hooked to the source voltage. if u know u are hooked up to the right wires, and no change, then the TPS could be bad. the voltage numbers here are not actual specs, just a round estimate of an area that it should be in.....hope this helps.

Just changed mine on my 2.2. That is exactly how you do it.
