Passat Syncro Wagon V6-2.8L (ATQ) (2000)
Note:
The Engine Control Module (ECM) calculates the voltage values of the angle sensors in percent relative to 5 volts and displays these
percentage values. (5 volts supply voltage represents 100%).
-
Depress accelerator pedal slowly until Wide Open Throttle (WOT) and observe percent indicated in display fields 3 and 4:
Percent indicated in display field 3 must rise uniformly. The tolerance range 12 to 97% is not completely used during this.
Percent indication in display field 4 must rise uniformly. In the process the tolerance range of 4 to 49% is not completely utilized.
Note:
The indicated value in display field 3 must always be about twice as large as the value in display field 4.
If indications do not resemble description:
-
Check voltage supply and wire connections of sensor for accelerator pedal position
