Application Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE-style replacements. Part number 350-34059 is built for the specified downstream positions and is intended to restore the diagnostic feedback the ECU expects from the sensor circuit. This part number 350-34059 is listed for 2014-2017 Honda Accord, downstream front; 2006-2015 Honda Civic, downstream bank 1 sensor 2 on specific vehicle models; and 2013-2014 Acura ILX, downstream bank 1 sensor 2 on specific vehicle models.

This part cross-references no listed interchange part numbers in the provided data.

What It May Help Resolve

• Check engine light related to downstream oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough engine operation tied to sensor signal issues
• Elevated exhaust emissions from a failing oxygen sensor
• Fault codes stored in the ECU for the affected sensor circuit

Installation Notes

Confirm the exact position before installation: 2014-2017 Honda Accord uses the downstream front location, while 2006-2015 Honda Civic and 2013-2014 Acura ILX use downstream bank 1 sensor 2 on specific models. Inspect the sensor wiring harness and connector for damage before replacement, and verify the threaded mounting point and connector style match the original part.
