A worn sensor can show up as a check engine light with an oxygen sensor code, or as a drop in fuel economy. Before you replace this sensor, rule out an exhaust leak or damaged wiring and connectors, because those can trigger oxygen sensor codes as well. A shop can scan the codes and test the sensor.
