Re: 2006 engine light off and on
Welcome to the garage.
What are the actual codes you got? The light comes on when its hard to start? When it is hard to start, does the starter motor turn rapidly, or does it seem to be slow? Did you check the battery condition already?
O2 sensor should not have to do anything with a hard start, since the O2 sensor output is not used until the engine warmed up a bit. Also donīt see any reason for a transmission sensor to cause a hard start.
