Colaborating the Voltages on the TPS

[beeza]

I've been searching but can't find any info on how to do this?
Cheers.

Closed throttle = .46 Volts
Open throttle = 4.5 Volts?

I found it :)

- Get several feet of wire. At least 6ft to make life easy. Cut them into 6 1' pieces and strip the ends. Now twist 2 pieces of wire together. So now you have 3 2' wires with the ends stripped and a stripped spot in the middle.
- There are 3 wires/pins for the tps sensor. 2 outside wires are ground and 5v source. Middle wire is the return voltage on the tps.
- Remove the throttle body, and connect your new spliced wires to the pins on the tps sensor on the throttle body and the pins on the wiring harness.
- Now connect your multimeter to the 2 outside wires (easiest to do this at the stripped points in the middle of the wires). This will also show you which wire is ground and wich is 5v.
- Turn the ignition to on (but do not start the car).
- Verify that you have 5v going to the tps.
- Now connect the multimeter to ground and the middle wire to measure tps voltage.
- TPS sensor is held in place by 2 screws. Open the throttle rotor to WOT and keep rotating the sensor until you get the output shown on the multimeter to 4.5v.
- Tighten tps sensor down & adjust idle setting screw shown in the pic below. Adjust this until the idle reading on the tps is about 0.48-0.49v.
- Now double check that WOT & idle tps readings are correct and put it all back together.


Ok,after reading this for 45 minutes,I think I got it figured :)
Just 1 thing,it says 'remove throttle body' but is it necessary? I don't see why...

My TPS was riveted on but I replaced it so now it's screwed in and I think it needs the voltages to be set.

Can I bump this benny :)

[beeza]

Do I need to take the TB off?
bump.

[beeza]

I asked my mechanic and he said you don't need to take off the TB.

yeah man, doesn't sound like you need to.

As long as those wires don't short on the block/IM you'll be ok. :thumbsup:

[beeza]

Great point Jase! Thank U,I'm sure that saved me a lot of troublr :/

It might be better to stick the probe on the multimeter in the TPS wire slots or a paperclip even and read the voltages off that?

[JasonGilholme]

my multimeter has nice long tapered pointers on it to fit inside plugs to get readings. If yours doesn't then a paper clip of other similiar item should do the trick.

Anything that stops you from having to cut your loom is a good idea. :thumbsup:

[beeza]

haha,Thanks Jase!

Electricals/multimeters...it's all newish to me but I'm figuring it out :)

[JasonGilholme]

yeah its good fun, just be cautious of shorting things out and you'll be fine. (mainly due to exposed wires dangling/flicking around)

[beeza]

Gotcha,cheers mate!
