Analog Theory

So if the PST2 at key on only shows actual value of Throttle Plate Angle % as 80 (and an air box removed manual check confirms throttle intake position does appear and feel wide open is that 80% signal correctly within range for the ECU to load a WOT map?

I seem to recall that as wot when I used the scantool software last year. Let's wait for another yes vote....memory slipping.

Workshop Manuals says:

Prerequisites:
The idle position of the accelerator cable
must be correctly adjusted.
Kickdown switch in installation position.
(see page 38 -point 3).

1. Connect system tester 9288.
2. Unhook pushrod from accelerator pedal.
3. Switch on system tester and select throttle
valve in DME factual values menu.

4. With the push rod unhooked, push the accelerator
pedal down to the stop (throttle
valve open up to stop) and read throttle
position 1 off on system tester.
Note
With the throttle valve open (accelerator pedal
fully depressed), the position is 84 degres +/- 30.
5. Hook push rod back onto accelerator pedal.
6. Push gas pedal down as far as possible
without operating kickdown switch and
read off throttle position 2 on system
tester.
The position indicated must be 3 degrees less than
position 1 (tolerance +/- 10 degrees).

Note
If the angle is too large, set the pushrod to a
shorter position.
If the angle is too small, set the pushrod to a
longer position.
After resetting the length of the pushrod,
check the angle. It must not be smaller than
79°.

Awesome thank you

I was just re-reading the above. The heading for that is "Adjusting Kickdown Switch".

Also, I find it hard to believe that +/- 30 degrees is accurate. My guess is that it is a typo in the manual and should read +/- 3 degrees!

And the second one might be +/- 1 degree, not 10.

Peter,
You are spot on with those noted specs as being typos!

Good to know, didn't make sense the way it's printed!
