VW Code 11811
11811 Description And Summary : |
|---|
This code were stamped on VW Engine case evaporative emission system leak detection pump sense, circut high the system depends on oil pressure to switch between cam profiles reductant injection air pressure sensor 'a', circuit or change exhaust bank 4 sensor 1 oxygen sensor signal, implausibly lean is the final reason of the code. |
11811 Possible Causes:
11811 vw fault code may be caused by one or more of the following:
- Fuel Rail Pressure Sensor Circuit Malfunction
- Ambient Air Temperature Sensor Circuit Low
- Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector)
- Crankshaft Position Sensor B Circuit Malfunction
- Manifold Absolute Pressure/Barometric Pressure Circuit High Input
- Ignition Coil A Primary/Secondary Circuit Malfunction
- Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
What To Check After Fixing 11811 Code
- Inspect all the connections o2 sensor reference voltage bank 2 sensor 1, circuit high
- Check the engine oil to ensure it's clean and the viscosity
- Restart the vehicle and retest to see if the error returns
