Walker 250-241253 Oxygen Sensor - Downstream Rear

OE Oxygen Sensor for Honda Odyssey

Walker Products OE oxygen sensor Part Number 250-241253 is an Original Equipment-style replacement for select Honda Odyssey applications. It is built for the specified sensor location and provides the ECU with the feedback needed for proper engine management and emissions control.

Key Features

• Walker Products OE line oxygen sensor for emission control systems
• Application-specific fitment for the correct sensor position
• Supports ECU feedback for air-fuel and exhaust monitoring
• Direct replacement for select Honda Odyssey downstream locations
• Part Number 250-241253 for easy identification

Fitment Details

Compatible with 2025 Honda Odyssey, downstream right. Compatible with 2022-2024 Honda Odyssey, downstream rear. Compatible with 2018-2021 Honda Odyssey, downstream rear. This part number, 250-241253, is also referenced for the same application as Walker Products OE oxygen sensor 250-241253.

What It Helps Address

• Stored oxygen sensor fault codes in the ECU
• Illuminated malfunction indicator light related to the sensor circuit
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel control
• Higher exhaust emissions from a failing downstream sensor

Installation Notes and Tips

Verify the sensor position before installation, since the Honda Odyssey uses different downstream locations across model years. Inspect the sensor wiring harness and connector for damage before replacing the part, and confirm the connector routing matches the original layout. For 2018-2021 Honda Odyssey applications, the rear downstream oxygen sensor must be installed in the correct position.
