A4 Quattro Cabriolet V6-3.0L (BGN) (2005)
Display on VAS5051:
1. Enter display group
-
Enter "062" for "display group number 062" in zone -2- and confirm entry by pressing -Q- button.
Display on VAS5051:
-
Check specified values for electronic throttle potentiometer voltages in display zones -1- and -2-.
NOTE: The engine control module converts and displays the voltage readings from the angle sensors as percentages of 5 V. (A 5 Volt supply
corresponds to 100%).
-
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 square button.
