A worn oxygen sensor can show up as a rough idle, weaker fuel economy or a check engine light, though an exhaust leak or a wiring fault can look similar. With the engine off and cool, look over the harness and connector for melted insulation or damage before you replace the sensor. The downstream position takes a single sensor, and this listing is one.
