10. On pressing the validation key, the diagnostic tool
will send a command that drives the primary throttle
to the fully closed position. The tool will also display
the voltage reading coming from the throttle position
sensor which will be needed for a check/adjustment
made later in the process.

11. Tighten the stepper arm nut until a clearance of
0.5 mm can be measured between the idle speed
control cam and the throttle roller (see the diagram
below).

12. Check the voltage reading on the tool. If the reading
is 0.6 volts +/- 0.02 volts, MAKE A NOTE OF THE
EXACT VOLTAGE READING then proceed to
step 18. If the reading is not within this tolerance
band, adjustment must be made as described in
steps 13 to 15.
13. Slacken the retaining screw on the primary throttle
position sensor.

1. Primary throttle position sensor
14. Gently turn the primary throttle position sensor until
the voltage reading on the tool shows 0.6 volts +/-
0.02 volts. MAKE A NOTE OF THE EXACT
VOLTAGE READING.
15. TIghten the sensor retaining screw to 3.5
Nm
and
recheck the voltage reading shown on the tool.
Repeat the adjustment if the reading is outside the
specified range, NOTING THE FINAL VOLTAGE
READING IF ADJUSTMENT IS MADE.
16. Press the validation key marked
'*'
to progress to
the next adjustment.
lZ On pressing the validation key, the diagnostic tool
will send a command that drives the primary throttle
to the fully open position. The tool will also display
the voltage reading coming from the throttle position
sensor.

18. With the stepper fully opened, check the voltage
shown on the tool and adjust the nut on the top of
the stepper arm until the tool shows a voltage
equivalent to X+0.12 (+/- 0.05Vl where X~ the
voltage measured in step 12 (or 15 if re-adjusted).
