Porsche 924 B3091 Troubleshooting

White smoke means that the fuel that is being injected into the combustion chamber is not being burned properly. The common causes that produce white smoke range from something as simple as low engine compression or water in the fuel to the fuel pump timing being thrown off because something is starving the fuel from getting to the pump in the manner necessary for the pump to time and work correctly. Porsche 924 B3091 OBD2 may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
