Intake Manifold Runner Position Sensor 1, Checking

Special tools, testers and auxiliary items required

• Multimeter.

• Wiring diagram.

Test requirements

• Fuses for engine electronics OK.

• Parking brake engaged.

• Battery voltage at least 12.5 V.

• Vehicles with automatic transmission, shift selector lever into position "P" or "N".

• All electrical consumers such as, lights and rear window defroster, switched off (radiator fan must not run during test).

• A/C switched off.

• The fuel tank at least 1/4 full.

• Ignition switched off.

Test procedure

- Perform a preliminary check to verify the customer's complaint. Refer to => [ Preliminary Check ] Preliminary Check.





- Disconnect the electrical harness connector from the Intake Manifold Runner Position Sensor (G336) - 1 -.

Checking voltage supply





- Using a Multimeter , check the electrical harness connector for voltage.





If specified value is obtained:

- Replace the Intake Manifold Runner Position Sensor (G336)

If specified value is not obtained:

Checking wiring connections

If the manufacturers test box is being used, perform the following step.

- Connect the Test Box 105 Pin (VAG1598/42) with Adapter Cable (1598/39-1).

If the manufacturers test box is not being used, perform the following step.

- Remove the Engine Control Module (ECM) (J623) => [ Engine Control Module, Replacing ] Engine Control Module, Replacing.





- Using a Multimeter, check the following wire connector 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 Battery positive (+) or an open circuit.

- If necessary, repair the wiring connection.

If no malfunctions are found in wires:

- Replace the Engine Control Module (ECM) (J623) => [ Engine Control Module, Replacing ] Engine Control Module, Replacing.

The Intake Manifold Runner Position Sensor (G336) must be adapted to the Engine Control Module (ECM) (J623).

To adapt the Intake Manifold Runner Position Sensor (G336) to the Engine Control Module (ECM) (J623) 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 Sec.

- The Engine Control Module (ECM) (J623) will automatically adapt the Intake Manifold Runner Position Sensor (G336).

- Assembly is performed in the reverse of the removal.

After 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 ] Diagnostic Mode 03 - Read DTC Memory.

2. If necessary, erase the DTC memory. Refer to => [ Diagnostic Mode 04 - Erase DTC Memory ] Diagnostic Mode 04 - Erase DTC Memory.

3. If the DTC memory was erased, generate readiness code. Refer to => [ Readiness Code ] Monitors, Trips, Drive Cycles and Readiness Codes.
