I fiddled with the TPS today, I went by a manual/investigation on hesitation to make sure I had the right voltages for it -

TPS is to have an input of 5V and a variable output of 0.45-4V and then an earth too

Mine was set at o.23V which is probably confusing everything, I've now set it up to 0.451V and it rotates all the way to 4V however it seems that my full throttle is a little higher than that and a 'no load' appears on my multi meter..?

 

But fine its set up properly now, I also looked at the Idle connector on it too, the manual says a 12V input and when throttle is closed a 9-10V output, when you push the throttle it should then disconnect and show 0V

I measure mine and I do have a 12V input, but my output is only 0V nomatter where the throttle is, I think the connection may be broken within the TPS.

Does anyone have any photographs of the internals of a Z32 TPS?

I found a video of a Z31 TPS at this link, about half way through it shows it in action.

And from this I can see, if the internals are out of shape, that the idle will be disconnected all the time. but as I say, this is a Z31 TPS, it looks rather similar to the Z32, but its missing the second set of wires.

 

Has anyone ripped one of these apart and got photos?

Hey - not a problem as I said, I'm around for another 4 weeks anyway.

I look forward to seeing you soon.

 

Any ideas / photos to help with the lack of idle switch? anyone?

 

cheers!

So i just took my Z out for a test run, it feels much more responsive and doesnt smell of petrol as much, which is great! so the overfueling could be sorted/better than it was!

However, due to having no idle switch output the idle is wandering and when I first push the throttle the revs drop by 200-400 revs before it catches itself again this often almost causes the engine to stall, which sucks.

Has anyone taken theyre TPS apart?

 

Cheers
