A4 V6-3.0L (AVK) (2004)
Display Group 062
-
Observe readouts in display zones 1 and 2.
-
Slowly depress accelerator pedal.
-
Percentage displayed in zone 1 should rise evenly. Tolerance range from 3 to 93% is not fully utilized.
-
Percentage displayed in zone 2 should fall evenly. Tolerance range from 97 to 3% is not fully utilized.
NOTE:
-
The reason why the value in display zone 1 rises and that in zone 2 falls is that the potentiometers (angle sensors) in the throttle valve control
module operate in opposite directions.
-
This means that the voltage picked off by one of the angle sensors runs in the direction of 5 V. (As the throttle is opened, the voltage becomes
greater and the percentage increases).
-
The voltage picked off by the angle sensor 2 runs from 5 V in the direction of 0 V. (As the throttle is opened, the voltage becomes smaller and
the percentage decreases).
-
Exit function "08 - Read measured value block" by pressing <- button.
If the displays are not as described:
-
Check throttle valve control module voltage supply and wiring. Pay particular attention to connectors, which may be disconnected or corroded.
-
Check accelerator position sensor. See: Accelerator Pedal Position Sensor/Testing and Inspection
Checking The Voltage Supply To The Throttle Valve Control Module.
-
Disconnect connector from throttle valve control module.
-
Switch ignition on.
-
Connect multimeter as follows to measure voltage:
