Sorry another "automotive electricians" please help me thread!

G'day Folks,

I feel the need to post here in OD because tech help is so slow these days =>

Today I spent 30 minutes of my life with a multimeter. Ug...

...anyway I made measurements from the throttle valve connector back to each and every pin on the ECU plug.

(I did this because I've still got random stalling and a fixed 20% error code via duty cycle measurements once the engine / coolant is warm)


Grasping at straws but found some potentially weird ****.


The green coloured results are the correct specifications according to the FSM / WIS information I have.




Blank spaces are a measured "infinite ohms" reading

Dashes are not applicable


Here's what I think I have found.

1) Pin #1 (idle sensor wire) is connected some how (slightly) to ground
2) Pin #3 (WOT sensor wire) seems to only be connected to itself

Now I would expect the WOT wire not being connected to anything else would be a good thing but the ECU is telling me there's a problem here. What the ****?

I can also measure high resistance connections between the throttle position ground and the road speed sensor, the OVP, and the fuel pump relay.

Strange.

Anyway if anyone knows if 2.3 KILO ohms or 12 KILO ohms is worth getting up set about (when I'd expect things to be not at all connected to each other) please let me know.

Those in the know please enlighten me

Suggests there's nothing wrong with the WOT switch to me
