Checking Wiring

NOTE:
For functional testing of the Throttle Position Sensor (TPS), also see On-Board Diagnostics, "Read Measuring Value Block" function 08, display group 002. Testing and Inspection

CHECKING WIRING TO ENGINE CONTROL MODULE
- Connect VAG 1598 test box with VAG 1598/11 adapter harness to the Engine Control Module (ECM). Connecting VAG 1598/31 Test Box
^ Adapter harness for ECM is not connected.

6-Pin Connector:

- Test for continuity between throttle position sensor Ground terminal 2 and test box socket 45.
^ Specified value: maximum 1.0 ohm
- Test for continuity between throttle position sensor positive terminal 1 and test box socket 46.
^ Specified value: maximum 1.0 ohm
- Test for continuity between throttle position sensor signal wire terminal 3 and test box socket 47.
^ Specified value: maximum 1.0 ohm

If specifications are not achieved:
- Determine open and/or short circuit in wiring harness between 6-pin TP sensor connector in engine compartment and ECM connector -A- according to wiring diagram, and repair as necessary.

3 7
2 Ground (GND)

NOTE:
Use only gold-plated terminals for repairing terminals in the terminal connector for throttle position sensor.

- Check and erase Diagnostic Trouble Code (DTC) memory.

If there is no malfunction in wiring harness or connections:
- Replace ECM .
