I just bought a used 2000 9-5 wagon, after the first long drive we had an engine light icon show up on the dash. Diagnosis by the defaler was error message 420, what does this message mean?
Thanks in advance for your time

If it was a real dealer he could tell you immediately...

If it was code P0420 then that is 'Three Way Catalytic Convertor. Malfunction', what this means needs your dealer to do some work and diagnose the actual fault from the error code rather than just read off what the OBDII unit says. Have you a warranty with the car?
This site gives you a description of the fault;
