what do you mean by "back probe"? im electronically retarded, does this just mean checking voltage at the connetor?
Pretty much. You need to make/use a thin wire on the end of you multimeter and go into the back side of the connector while it is attached to the TPS. Or, you can pierce the wires with the multimeter probe, but I avoid this if possible as it can lead to corrosion issues.
Should go something like this:
Black - ground (at least for the TPS circuit - may not be a vehicle/chassis ground).
Gray - this is the 5 vdc regulated reference voltage generated by the TCM.
Blue - this is the variable output of the TPS. Should about 0.5 vdc at idle and 4.5 vdc at full pedal.
(wire colors may be wrong, check it out yourself first)
You're looking to verify that the TPS is putting out the 0-5ish volts that it should be, dependent on throttle position.
WW is right, you may just be way out of adjustment since you moved the sensor. I sounded like you took the sensor off, the spring snapped the sensor back and you bolted it back on. Is this true?
If so, you've probably got the sensor installed wrong. The voltage check will tell you if it is. If you don't see the .5 v at idle position, you need to rotate the TPS (if the holes are slotted) until you do.
While I can't say for sure with a 93 TPS, most are "loaded" against the throttle shaft by an internal spring. They usually need to be installed and turned slightly to load the spring and set the idle voltage.
Check it out though, like I said I'm not sure about the specifics on a 93....
it also goes into every gear, but when you move it up from one to two, it never shifts up. my '95 looses manual gears in limp mode, so thats what i figured was happening.
So, are you saying it shifts when driving but not when you move the shifter manually?
Not sure what you're saying there....
