Ok me and my brother in law conected a volt tester to it with the ignition on and it gave us the 5v from the ecu, now about testing it open and closed, do i do it wile the car is off or with the ign on? and lets says its doing all that should i check for something else or what, and what if the next two things are not giving those two readings.The top diagram in post #14 shows the throttle angle sensor/TPS. Check whether the sensor gets 5 reference volts from the ECU and that it outputs about 0.5V with the throttle closed and about 4.5V with the throttle wide open.
im kinda confused what do u mean with it closed and open, sorry im just new at all this.
btw did u see the pics from my tb i posted post #18 seems like i have no idle screw, and i dont see my fitv either. lol weird

That's good.

Test is done with key in ON(II). Closed = throttle pedal not pushed down. Open = throttle pedal pushed all the way to the floor. Post the results.

ok i just re tested how u said but it just stays at 5v don't know what to do know, im trying to follow the manual on the tp sensor part, and one of the procedures is: Connect the test harness between the ecm and connectors. Now im confuse there, does that need to b done in order to do the procedure that u gave me which comes right after tha,t or is it not necessary.

wait again im confused there, if i connect back the tps how will i connect the probe to test for voltage. i wish there was a video around on this, i get all lost lol.The test is done with the TPS connected to its plug. To measure voltage, back probe the middle Red/Blu wire in the TPS connector with the red (+) meter probe and back probe the Grn/Wht ground wire with the black (-) meter probe.

Some probes of digital multimeters have a sharp tip that allows you to penetrate the wire insulation to contact the metal wire. Otherwise, carefully expose a small patch of insulation for the test.wait again im confused there, if i connect back the tps how will i connect the probe to test for voltage. i wish there was a video around on this, i get all lost lol.

ok got u there, but i read in the manual that doing that is not good, have u done that ur self?, yesterday when i retested how u said it was staying in 5v's cuz i was doing it with it unplugged maybe that is the reason why it did not react at opened and closed.Some probes of digital multimeter s have a sharp tip that allows you to penetrate the wire insulation to contact the metal wire.

im so sorry im asking so much , i just really wanna take care of it and not mess up.

I try to avoid giving bad advice. The procedure that I described is commonly used to calibrate the TPS.

What specific TPS wire (color) are you measuring voltage from? Correct, calibration requires the TPS connector to be plugged in. In addition, you probe different wires for calibration versus reference voltage.
