Key Features
- Heated oxygen sensor for downstream exhaust monitoring
- Specific-fit design for direct application matching
- 4-wire configuration with a 20-gauge harness
- Threaded mounting with 18.0 mm thread diameter
- Radiused polygon connector, male terminal
- Wiring harness length: 29.06 in.; overall length: 32.6 in.
Product Details
Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for OE-style replacement use. Part number 350-34282 is intended for downstream sensor positions on select vehicles, including 2009-2013 Toyota Corolla, 2009-2013 Toyota Matrix, 2014 Toyota Matrix, 2006-2010 Lexus SC430, and 2009-2010 Pontiac Vibe. In these applications, the sensor supports exhaust monitoring and ECU feedback for the downstream system. This part cross-references no listed interchange numbers in the provided data.
Common Issues This Sensor Can Address
- Check engine light related to downstream oxygen sensor performance
- Poor fuel economy caused by inaccurate exhaust feedback
- Rough engine operation tied to sensor signal faults
- Higher exhaust emissions from a failing oxygen sensor
- Stored ECU fault codes for the affected sensor circuit
Installation Notes and Tips
Verify the vehicle’s downstream position, connector style, and thread size before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life. Confirm the exact application by year, make, model, and sensor location before replacing the original unit.
Quality Assurance
Walker Products has produced engine management components since 1946 and operates as an ISO 9001 / TS 16949 certified company. The 350-34282 oxygen sensor is manufactured for specific fitment and ECU feedback requirements in the listed applications.
