Details

Replace the oxygen sensor when fuel consumption rises or the check-engine light appears, since it regulates the air-fuel mixture to keep the engine efficient and emissions low.

• Replacement sign: Higher fuel use, an illuminated check-engine light, or rough idling.
• Approximate lifespan: Typically lasts 100,000 to 150,000 km depending on driving conditions and fuel quality.
• Install requirement: Requires a dedicated sensor socket; professional installation with ECU reset if needed is recommended.
