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 the voltage supply was OK:
-
Replace the Throttle Position (TP) Sensor G79 / Accelerator Pedal Position Sensor 2 G185.
If no malfunction is detected in the wiring and if the voltage supply was not OK:
-
Replace the Motronic Engine Control Module (ECM) J220.
-
Install the drivers side storage compartment.
Final procedures
After 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 - Read DTC Memory
2. If necessary, erase the DTC memory. See: Testing and Inspection/Scan Tool Testing and Procedures/Diagnostic Mode 04 - Erase DTC Memory
3. If the DTC memory was erased, generate readiness code. See: Testing and Inspection/Monitors, Trips, Drive Cycles and Readiness Codes
-
End of diagnosis.
