Detailed Description

Walker Products OE 250-24343 is designed for vehicles that require a direct replacement oxygen sensor in the correct upstream or downstream position. It is a heated sensor with a 4-wire layout, 20-gauge wire, and a threaded mount, making it suitable for precise ECU feedback on emissions-equipped Honda and Acura platforms. This part number 250-24343 is listed for downstream bank 1 sensor 2, downstream rear, downstream front, and upstream positions depending on the vehicle and model year.

Compatible With 1998-2005 Honda Accord, 1998-2001 Honda Prelude, 2000-2005 Acura NSX, 2000-2005 Honda Odyssey, 2000-2003 Acura TL, 2001-2005 Honda Civic, 2001-2005 Acura EL, and 2001-2003 Acura CL applications where the fitment table specifies the sensor position. Walker Products OE replacement sensors are built for application-specific installation and diagnostic response.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate exhaust readings
• Elevated exhaust emissions from a failing sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

Install only in the exact position shown in the fitment data, since upstream and downstream sensors are not interchangeable. Inspect the sensor wiring harness and connector for damage before installation, and verify the connector shape, thread diameter, and harness length against the original part. For 2004-2005 Acura EL, 2001-2005 Honda Civic, and 2000-2002 Honda Accord applications, confirm the listed downstream bank 1 sensor 2 position before ordering. For 2001-2003 Acura EL and 1998-2001 Honda Prelude applications, confirm the upstream position shown for the vehicle.
