B2246 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. Parts or components should not be replaced with reference to only a B2246 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
