Code p0240 catalyst efficiency low. 2008 malibu LTZ with 3.6. enginen light has been on for several months, performance hasn't been effected, have cleared the code many times but come back within a da

Asked by mrex04 Aug 15, 2014 at 12:01 PM about the 2008 Chevrolet Malibu LTZ FWD

Question type: Maintenance & Repair

Initially I thought it could be the catalytic converter, but the performance hasn't been
affected at all. Is it possible to have a bad O2 sensor and still get this code?

mrex04 answered 10 years ago

What is your recommendation as how to fix the problem? Should I replace the down stream O2 sensor?
