Attached are the photos from the disassembly of the TPS/idle switch assembly.
Besides the actual TPS's carbon tracks wearing out, another issue is the actuating arm. When you zoom in on the photo of the arm, you can see where it has split and I have repaired it with weatherproof heat shrink.
Once the TPS assembly is removed, it appears that the throttle body casting is likely the same as is used for manual transmissions as it looks like the mounting pylons are spaced about the same as is needed to mount the regular style throttle switch.
Measurements of the mountings and shaft of the throttle body......
Throttle shaft dia is 8mm.
Throttle shaft across the flat section is 6mm.
The throttle shaft extends 18.5mm from the TB housing.
When looking at the end of the throttle shaft, the throttle shaft rotates in a clockwise direction as the throttle is opened.
Spacing between the two mounting pylons is 70mm, this being from center to center of the mounting holes.
Mounting bolts are 4mm
I would like to be able to retain the large round plate as it is the mount for the weathershield boot that covers the TPS assembly. This simply makes it all look tidy.
