Special tools and workshop equipment 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 .
-- 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.
| Intake Manifold Runner Position Sensor -G336- Electrical Harness Connector Terminal | Specified value |
|---|---|
| 1 to Ground (GND) | Battery positive (+) |
| 2 to Ground (GND) | about 5 V |
| 3 to Battery positive (+) | Battery positive (+) |
If specified value is obtained:
-- Replace the Intake Manifold Runner Position Sensor -G336-. Refer to Component Locations Overview .
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 Cable1598/39-1. Refer to Component Locations Overview .
If the manufacturers test box is not being used, perform the following step.
-- Remove the Engine Control Module (ECM) -J623-. Refer to ENGINE CONTROL MODULE, REPLACING .
-- Using aMultimeter, check the following wire connector terminals for an open circuit.
| Intake Manifold Runner Position Sensor -G336- Electrical Harness Connector Terminal | Engine Control Module (ECM)J623 Electrical Harness Connector Terminal |
|---|---|
| 1 | 29 |
| 2 | 55 |
| 3 | 40 |
Specified value: 1.5 Ω 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-. Refer to 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:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
