Air / Fuel Ratio Sensor - OE Style | O.E. Quality Direct Fit Replacement Sensor
The air/fuel ratio sensor monitors exhaust gases to help the engine control module maintain the precise fuel mixture needed for clean combustion and optimal performance. Signs of failure include: a check engine light, poor fuel economy, rough idling, or a noticeable drop in throttle response. Replace a worn sensor before it leads to catalytic converter damage or a failed emissions test.
