I have a 2000 Ford Taurus. I currently have 135,000 miles on it. Recently my "Check Engine" light came on. I had it checked and it came back reading a P0430 Code(Catalyst Efficiency-low bank 2). How do I check whether or not I have a Catalytic converter, oxygen sensor or a mass air-flow unit problem? I don't wish to replace parts unnecssarily.
- Thanks Alot
have the same problem?
