Turn ignition off. Disconnect ECM harness connector, leave ECM disconnected from test box. Connect
Test Box (VAG 1598/31) or (VAG 1598/22) to ECM harness connector. See CONNECTING VAG
TEST BOX . Using DVOM, check resistance between APP sensor circuits and test box sockets. See
APP SENSOR 6-PIN HARNESS CONNECTOR/VAG TEST BOX SOCKET IDENTIFICATION
table. Record resistance readings. Resistance should be a maximum of 1.5 ohms for each reading. Check
wiring in APP sensor 6-pin harness connector for short circuits to one another, and for short circuits to B+
and ground. If resistance measurements are okay and no short circuits exist, go to next step. If any
resistance measurement is not okay, or a short circuit exists, repair circuit(s), as necessary. After repairs,
erase DTC memory. Verify repair. Test is complete. Perform ECM relearn procedure. See TEST DRIVE
RELEARN PROCEDURE .

5. Replace faulty APP sensors No. 1 (G79) and No. 2 (G185). Accelerator position sensors are an integral
part of the accelerator pedal assembly. After repairs, erase DTC memory. Adapt APP sensors to
Transmission Control Module (J217). See A/T BASIC SETTING . Verify repair. Test is complete.
Perform ECM relearn procedure. See TEST DRIVE RELEARN PROCEDURE .
NOTE:
If accelerator pedal assembly is replaced, APP sensors must be adapted
to the A/T control module.
NOTE:
APP sensor harness connector terminal No. 5 is for A/T models only.
