A worn oxygen sensor can bring on a check engine light, poorer fuel economy or rough running, but a damaged wire, an exhaust leak or a fuel fault can also bring those on. Before replacing the sensor, look over its wire and plug for melted insulation or damage with the engine off and cool. A shop can read the codes and test the sensor.
