What does it mean to have a code po 430 on a 2003 ford expedition


My code book says"Catalyst Efficiency Below Threshold(Bank 2).This means the computer sees that the readings between the O2 sensor before and after the catalytic converter show that the converter isn't cleaning the exhaust enough.This could be the sensors or the converter.I'm leaning toward the converter,but this only a guess.(O2 sensors can become sluggish and not read accurately,but the computer would most likely set a code for one of the sensors as well).

California illegal catalytic converter ford expedition 2003


Because the cat that is approved for California is "finer tuned" than the other 49 states. California emission standards are the toughest in the country, so many engine and emission parts are made just for those standards.

My 1999 Ford Expedition 4 wheel drive service light on the 4 wheel drive is on..saying "service 4 wheel drive"? what does this mean and is it harmful to use the 4 wheel drive with the light on?


Usally these warning lights come on for a reason.
I would have someone plug a OBD II reader in and retrieve the code.
The code should be able to tell you specific information on why the light is on.
Until you find out I would not us the 4 wheel drive function.

Ford Expedition Battery and system charge warning


If he replaced the battery that would have cleared the code. There is another issue. Was the alternator aftermarket? Just becuase it is new does not mean good. Those are easy to install I would return it to where you got it and try another.
