Product Details

Walker Products OE 250-54055 is engineered for 1998-2000 Honda Accord upstream oxygen sensor service, including Bank 1 Sensor 1 applications. The sensor uses a radiused polygon female connector, 20-gauge wiring, an 11.34 wiring harness length, and an overall length of 14.88 for application-specific fitment. As part of the Walker Products OE line, this sensor is built for direct replacement use where accurate exhaust feedback is required by the vehicle’s engine control system. This part number, 250-54055, is also referenced for front oxygen sensor service on select Honda Accord applications.

Common Issues This Sensor Can Help Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect air-fuel feedback
• Rough engine operation from inaccurate exhaust readings
• Higher exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the upstream position before ordering and compare the connector shape, wire count, and thread size to the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. For 1998-2000 Honda Accord service, verify Bank 1 Sensor 1 location and clear any stored fault codes after repair.
