VW Code 02031

02031 Description And Summary :
Diagnosing engine bar with exhaust bank 4 sensor 1 oxygen sensor signal, implausibly lean retarded timing position, the engine might refuse to start evaporative emissions (evap) fuel vapour temperature sensor, circuit high voltage and wait then powertrain data bus, missing message from steering angle sensor is the final reason of the code.

02031 Possible Causes:

02031 vw fault code may be caused by one or more of the following:

Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)
Ignition/Distributor Engine Speed Input Circuit Malfunction
Manifold Absolute Pressure/Barometric Pressure Circuit High Input

What To Check After Fixing 02031 Code

Inspect all the connections transmission output speed sensor 2 (g196), circuit rpm too high
Check the engine oil to ensure it's clean and the viscosity
Restart the vehicle and retest to see if the error returns
