Signs of failure include: a check engine light with an O2 sensor code, poor fuel economy, a rough idle, or a vehicle that fails an emissions test. Replace a worn oxygen sensor to restore proper closed-loop fuel control and fuel efficiency.\u003c\/p\u003e\n\u003cp\u003eWalker, part of Tenneco, manufactures exhaust systems, catalytic converters, and mufflers.
