Code P0420
I have a 2008 Saturn Vue Redline with 193K miles. Iím getting code P0420, Iíve replaced the O2 sensor and still have the same code. Is there any thing else I can do to fix this or is replacing the catalytic converts the only option?

Thank you,

Re: Code P0420
Carefully check for small exhaust leaks between the front and rear O2 sensors, especially the flex hose. A shop vac can supply air to pressurize the exhaust, use a soap and water solution to check for any bubbles. Any slight leak may set a code.
