S4 Quattro Sedan V6-2.7L Turbo (APB) (2000)
Display Group 62
NOTE: The engine control module converts the voltage readings from the angle sensors into percentages of 5 V and displays them as percentages. (A
signal wire voltage of 5 V is equivalent to 100%.)
-
Observe display fields 3 and 4.
-
Slowly depress accelerator pedal to full throttle position.
The percentage value in display field 3 should rise steadily, but without covering the full tolerance range between 3 - 93 %.
The percentage value in display field 4 should also rise steadily but without covering the full range of values (in this case 4 - 49 %).
The value shown in display field 3 should always be about the double of the value shown in display field 4.
If the display values do not appear as described:
-
Check voltage supply and wiring to accelerator position sensors.
