Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered to match original equipment requirements. Part number 350-341077 is built for the specified mounting position and diagnostic feedback expected by the vehicle ECU. For Honda vehicles such as the Accord, Civic, and CR-V, the sensor supports downstream monitoring where accurate exhaust feedback is needed to maintain proper engine operation and emissions performance.

This part cross-references no listed aftermarket numbers in the provided data. Walker Products 350-341077 is a direct-fit oxygen sensor for select Honda models, including 2016-2021 Honda Civic, downstream; 2017-2021 Honda Accord, downstream; and 2022-2024 Honda CR-V, downstream.

Common Issues This Sensor May Address

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

Installation Notes

Verify the vehicle’s exact year, model, and downstream position before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten service life and affect signal quality. Confirm thread size, connector style, and harness length against the original part before replacement.
