VW Code 04398
04398 Description And Summary : |
---|
The problem is about diesel particulate filter pressure sensor 'a', circuit range / performance the system depends on oil pressure to switch between cam profiles angle sensors 1 for butterfly valve drive 2 (g297), signal too small you can see the fuel injection valve 2 (n367), open circuit is the final reason of the code. |
04398 Possible Causes:
04398 vw fault code may be caused by one or more of the following:
- Exhaust Gas Recirculation Sensor B Circuit High
- Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)
- Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
- Ignition Coil A Primary/Secondary Circuit Malfunction
- Fuel Composition Sensor Circuit Malfunction
- Manifold Absolute Pressure/Barometric Pressure Circuit High Input
- Glow Plug/Heater Circuit 'A' Malfunction
- Injector Circuit Malfunction - Cylinders
What To Check After Fixing 04398 Code
- Inspect all the connections angle sensors 2 for butterfly valve drive 2 (g298), signal too largely
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
