Product Details
Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for OE replacement use. Part number 350-34351 is manufactured for the correct application and fitment position so the sensor can provide the diagnostic feedback expected by the ECU. If the original sensor is failing, the vehicle may run rich or lean, consume more fuel, increase exhaust emissions, or trigger a malfunction indicator light. This part number 350-34351 is a direct replacement style sensor for the specified application, and it is also referenced as Walker 350-34351 in catalog listings.
Walker Products has supplied engine management components since 1946 and operates under Automotive ISO9001/TS 16949 quality systems. This part cross-references no additional part numbers in the provided data.
What It Helps 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 heated O2 sensor
- Stored ECU fault codes tied to the sensor circuit
Installation Notes
Before replacement, inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals. Confirm the thread size, connector style, wire count, and harness length match the original unit before installation. Because this is a specific-fit sensor, it should be installed in the intended position for the application and verified with the vehicle’s diagnostic system after installation.
Quality Assurance
Walker Products manufactures engine management sensors under ISO9001/TS 16949 quality standards and builds this oxygen sensor as an OE replacement for the intended application. The part is engineered to provide the ECU feedback required for proper system operation.
