Hello, my name is***** code is almost never the oxygen sensors, almost always the catalytic converter. Possible problems for this code would be oxygen sensors, exhaust leak, or catalytic converter. Since oxygen sensors are new that leaves exhaust leak and catalytic converter as possible problem. Having converter replaced at exhaust shop would probably be your cheapest option. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

Does the Titan have the converter on the exhaust manifold or is it separated on its own
Expert:  Dan replied 12 months ago.

It has converter on exhaust manifold. Let me know if you have more questions, thanks.

If I took it to the dealer would it be more expensive or the exhaust shop would be better?
Expert:  Dan replied 12 months ago.

The dealership would be more expensive but I would would recommend getting quotes from dealership and at least 2 different exhaust shops. Let me know if you have more questions, thanks.
