-
Install the test box.
If the manufacturers test box is not being used, perform the following step.
-
Remove the Motronic Engine Control Module (ECM) ( J623).
-
Using a multimeter, check the Throttle Position (TP) Sensor (G79)/Accelerator Pedal Position Sensor 2 (G185) electrical harness connector
terminals to the Motronic Engine Control Module (ECM) (J623) electrical connector T94 for an open circuit or short to ground.
Specified value: 1.5 ohms max.
If the specification was Not obtained:
-
Check the wiring for a short circuit to each other, Battery (+), Ground or high resistance).
-
Check the electrical harness connector for damage, corrosion, loose 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 the Throttle Position (TP) Sensor (G79 )/Accelerator Pedal Position Sensor 2 (G185).

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.
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.
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.
