S6 Quattro Sedan V10-5.2L (BXA) (2007)
-
Using a multimeter, check the Intake Manifold Runner Position Sensor 2 (G512) electrical harness connector terminals to the Engine Control
Module (ECM) 2 (J624) electrical harness connector T60b terminals for an open circuit.
Specified value: 1.5 ohms Max.
If the specification was not obtained:
-
Check the wiring for a short circuit to each other, Battery (+), Ground (GND), or an open circuit.
-
Check the electrical harness connector for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If no malfunction is detected in the wiring:
-
Replace the Engine Control Module (ECM) 2 (J624). Refer to => [ Engine Control Module, Removing and Installing ] See: Powertrain
Management/Computers and Control Systems/Engine Control Module/Service and Repair/Engine Control Module, Removing and Installing.
The Intake Manifold Runner Position Sensor 2 (G512) must be adapted to the Engine Control Module (ECM) 2 (J624).
To adapt the Intake Manifold Runner Position Sensor 2 (G512) to the Engine Control Module (ECM) 2 (J624) perform the following steps:
Test requirements
‹› The battery voltage at least 12.5 V.
‹› Coolant temperature must be between 20° C and 80° C.
‹› No DTC's stored in DTC memory.
-
Start the engine and let run at idle for at least 70 seconds.
-
The Engine Control Module (ECM) 2 (J624) will automatically adept the Intake Manifold Runner Position Sensor 2 (G512).
Assembly is performed in the reverse order of removal.
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. Refer to => [ Diagnostic Mode 03 - Read DTC Memory ] See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Modes 01 - 09/Diagnostic Mode 03 - Read DTC Memory.
2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] See: Powertrain Management/Computers and
Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Modes 01 - 09/Diagnostic Mode 04 - Erase DTC Memory.
3. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code ] See: Powertrain Management/Computers and Control
Systems/Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes.
