Product Details

Part Number: 36532-5AA-A51
Brand: Honda

Maintain optimal engine performance and emissions with the Genuine Honda 36532-5AA-A51 Lower Oxygen Sensor (NGK). Designed and manufactured to Honda's exact OEM specifications, this downstream oxygen sensor monitors the oxygen content of exhaust gases after the catalytic converter, allowing the engine control module (ECM) to verify catalytic converter efficiency and maintain proper emissions system operation.

A failing oxygen sensor can trigger a check engine light, reduce fuel economy, and cause emissions-related diagnostic trouble codes. Replacing it with a genuine Honda sensor ensures accurate readings, dependable performance, and seamless integration with your vehicle's factory engine management system. This NGK-manufactured OEM sensor provides the quality, reliability, and fit expected from the original equipment installed at the factory.
