Product Details
The Honda OEM Air Fuel Ratio Sensor is a genuine factory replacement designed for the 2003-2007 Honda Accord equipped with the 2.4L K24 engine. Also known as the primary oxygen sensor, upstream oxygen sensor, or LAF sensor, this component plays an essential role in maintaining proper engine performance, fuel efficiency, and emissions control.
Located in the exhaust system before the catalytic converter, the air fuel ratio sensor monitors oxygen levels in the exhaust gases and sends real-time feedback to the ECU. The ECU uses this information to adjust fuel delivery, helping maintain the correct air-fuel mixture for efficient combustion.
Over time, oxygen sensors can deteriorate from heat, carbon buildup, contamination, and normal wear. A failing sensor may cause poor fuel economy, rough idling, hesitation, increased emissions, or a check engine light.
Manufactured to Honda's original equipment specifications, this sensor provides accurate readings, dependable performance, and factory-quality fitment.

Installation Notes
- Before replacing the sensor, inspect the electrical connector, wiring harness, and surrounding exhaust components for damage. Confirm that the original sensor is faulty through proper diagnostics, as exhaust leaks and wiring problems can produce similar symptoms.
- Allow the exhaust system to cool before removal. Disconnect the factory electrical connector and carefully remove the original sensor using an appropriate oxygen sensor socket.
- Install the replacement according to Honda's factory service manual, following the specified tightening torque. Avoid contaminating the sensor tip or damaging the wiring during installation.
- After installation, clear any related diagnostic trouble codes and verify proper engine operation.
Note:
- Includes one genuine Honda air fuel ratio sensor. Wiring harnesses, exhaust components, and additional oxygen sensors are sold separately unless otherwise specified.
This is the primary upstream air fuel ratio sensor, not the secondary downstream oxygen sensor located at the catalytic converter. Confirm the required sensor position before ordering.
