New Beetle L4-2.0L (AZG) (2003)
Check specified value for Sender for accelerator pedal position -G185at idling stop in display zone 4. Specification: 4...50%
Note: The Engine Control Module (ECM) calculates the voltage value of the angle sensors in percent relative to 5 volts and displays these
percentage values. (5 volts supply voltage represents 100%)
Depress gas slowly until Wide Open Throttle (WOT), and observe percent indication in display zones 3 and 4:
The percent indication in display zone 3 must rise evenly. The tolerance range of 12...97% will not be used in it's entirety.
The percent indication in display zone 4 must rise evenly. The tolerance range of 4...50% will not be used in it's entirety.
Note: The indicated value in display field 3 must always be approximately twice as large as the value in display field 4.
If the display does not indicate as described:
Check voltage supply and wiring connections of Sender for accelerator pedal position and Throttle Position sensor, Refer to Powertrain
Management, accelerator pedal position sensor checking, Testing and inspection
Checking voltage supply and wiring to control unit
Remove driver side storage compartment
Disconnect 6-pin harness connector for TP sensor and Sender for accelerator pedal position.
Switch ignition on.
Connect multimeter to the following terminal connector for voltage measurement.
Contact 1 + Ground (GND)
Contact 1 + 5
Contact 2 + Ground (GND)
Contact 2 + 3
Specification: at least 4.5 V
Switch ignition off.
If the specified values are not obtained:
Remove inner plenum chamber cover, left.
Connect test box VAG1598/31 to control unit wiring harness. The Engine Control Module (ECM) is not connected by this action.
