hey guys

hooked the multimetre up to the tps just to check all is ok

i got .45v closed which i'm pretty sure is spot in

but when i pulled the throttle cable to WOT i only got about 3.5v

car is an r32 gtst

also collant resistance was about .4 kOhms at nearly opperating temp, is this right?

Bringing back an old thread but didn't want to start a new one.

I'm getting the same thing, 0.5V when closed and 3.5V on WOT. What's the go with this, is this correct? I'm measuring it with the car on ignition and not actually running if that makes a difference, but electrically I don't see why it would. Comments?

the resistor on the throttle position sensor had a wider degree of movement, than the throttle they are connected to. Throttles all turn 90 degress, but most variable resistors turn 110 degrees or even a little more, so the full range of voltage can go from 0 or slightly above, to only 3.5 volts. The ecu "learns" what the full range of voltage is for the TPS thru driving. It calibrates itself.

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
