Rabbit L5-2.5L (BGP) (2006)
Checking wiring
If the manufacturers test box is being used. Perform the following step.
-
Install the test box.
If the manufacturers test box is not being used. Perform the following step.
-
Remove the Engine Control Module (ECM) J623.
-
Using a multimeter, check the Manifold Absolute Pressure (MAP) Sensor G71 electrical harness connector terminals to the Motronic Engine
Control Module (ECM) J220 electrical harness connector T121 terminals for an open circuit.

Specified value: 1.5 Ohms max.
If the specification is not obtained:
-
Check the wiring for a short circuit to each other, Battery (+), and Ground (GND).
-
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 and if the voltage supply was OK:
-
Replace Manifold Absolute Pressure (MAP) Sensor G71.
If no malfunction is detected in the wiring and if the voltage supply was not OK:
-
Replace the Motronic Engine Control Module (ECM) J220 .
Final procedures
After the repair work, the following work steps must be performed in the following sequence:
1. Check the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 03: Interrogating Fault Memory
2. If necessary, erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04: Reset/Delete
Diagnostic Data
3. If the DTC memory was erased, generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
