Service & Repair Manual

24-151
Notes:
The reason why the value indicated in display
field 1 climbs, while the value indicated in
display field 2 decreases, has to do with the fact
that the potentiometers (angle sensors) in the
throttle valve control unit run in opposite
directions.
This means that the voltage tap of angle sensor
1 runs from 0 to 5 volts. (The more the throttle
valve is opened, the larger the voltage; percent
indication climbs).
The voltage tap of angle sensor 2 runs from 5
to 0 volts. (The more the throttle valve is
opened, the lower the voltage; the percentage
decreases).
If indications do not resemble description:
- Check voltage supply and wire connections of
throttle valve control module Page 24-152 .
Pay particular attention to harness connectors
that could be loose or corroded.
- Check accelerator pedal position sensor Page
24-154 .
