Details

Replace the heated oxygen sensor when the check-engine light appears or fuel economy and performance drop, since a weak signal upsets the air-fuel mixture and raises emissions.

• Replacement sign: Check-engine light on, higher fuel consumption, and rough idling.
• Approximate lifespan: About 100,000 to 150,000 km depending on sensor type and driving conditions.
• Install requirement: Requires a dedicated oxygen-sensor socket, and clearing fault codes after fitting may be needed.
