Description
Product Overview
The Walker Products Oxygen Sensor (model 350-34286) is engineered as a direct OE replacement for a wide range of modern automobiles. Its core comprises a dual lower shield ceramic element that delivers precise oxygen detection across the full operating temperature range. The sensor body is machined from high‑grade steel and laser‑welded to the shields, providing exceptional structural integrity and resistance to vibration. A plasma‑sprayed protective coating shields the ceramic from corrosive exhaust gases, while an internal high‑temperature sleeving protects the wiring from heat spikes up to 900 °F. The flange‑mount design fits securely to the exhaust manifold without additional brackets, and the push‑pull output delivers a clean, linear voltage signal for accurate engine management. Measuring just 2.2 × 2 × 5.9 inches and weighing only 5.1 ounces, the sensor blends compact dimensions with robust construction. Its modern aesthetic and machined exterior complement both performance‑oriented and OEM‑style applications, making it a versatile choice for professional technicians and DIY enthusiasts alike.
The sensor’s output type is push‑pull, which simplifies wiring and reduces the need for additional signal conditioning modules. Its flange mounting eliminates the need for custom brackets, saving installation time and reducing potential leak points. The ceramic element is calibrated to meet OEM specifications, ensuring that the engine control unit receives accurate feedback for fuel mixture adjustments, which helps maintain emissions compliance and optimal fuel economy. With a best‑in‑class response time of less than 0.5 seconds, the sensor quickly adapts to rapid changes in exhaust composition during acceleration, deceleration, and idle conditions. The protective plasma coating also extends service life by resisting soot buildup and chemical attack, allowing the sensor to perform reliably for up to 100,000 miles under normal driving conditions.
Designed for both OEM and aftermarket installations, the sensor conforms to the original part number 350-34286 and matches the OEM part numbers 15047, 23134, 234-4597, SU3113, SG1623, 213-2999, ES20207, OS5082, and 11288, ensuring seamless fitment across multiple vehicle makes. Its compact size allows it to be installed in tight engine bays without interfering with surrounding components. The sensor’s exterior finish is machined to a smooth surface, reducing the risk of debris accumulation and facilitating easy cleaning during routine maintenance. Additionally, the product carries the UPC 724620091032 and GTIN 00724620091032 for straightforward inventory tracking and compliance with retail standards.
All specifications are verified against the original equipment documentation, and the sensor meets ISO 9001 quality standards. The combination of advanced materials, precise engineering, and rigorous testing ensures that the Walker Products Oxygen Sensor delivers consistent performance throughout its service life, helping maintain engine efficiency and meet emission regulations.
Installation requires only standard tools and the sensor’s flange aligns with the OEM mounting holes, reducing installation time to under ten minutes for experienced technicians.

Usage
The Walker Products Oxygen Sensor is designed for use in a wide variety of gasoline‑powered vehicles, including cars, light trucks, and SUVs that rely on electronic fuel injection systems. It replaces the original sensor in the exhaust stream to monitor oxygen levels, providing the engine control unit with real‑time data that governs fuel delivery, ignition timing, and emissions control. Technicians typically encounter this sensor when diagnosing check‑engine lights related to lean or rich fuel mixtures, poor fuel economy, or failed emissions tests.
During installation, the sensor is mounted directly onto the exhaust manifold or header using its flange‑type mounting hardware. The push‑pull electrical connector plugs into the vehicle’s wiring harness, delivering a clean voltage signal that varies proportionally with the oxygen concentration in the exhaust gases. Because the sensor’s output is linear, it eliminates the need for complex signal conditioning, allowing for straightforward integration with most aftermarket engine management systems.
The sensor performs optimally in both cold‑start conditions and high‑temperature operation. Its high‑temperature sleeving protects the internal wiring from heat spikes, while the plasma‑sprayed coating shields the ceramic element from corrosive gases and soot buildup. This durability translates to reliable operation over thousands of miles, reducing the frequency of sensor replacements and minimizing vehicle downtime.
For DIY enthusiasts, the sensor’s compact dimensions and standard mounting pattern make it a convenient upgrade or replacement. No special tools beyond a basic socket set and torque wrench are required, and the installation can be completed in a typical home garage within an hour. Professional repair shops appreciate the sensor’s OE‑level fit and performance, which helps them meet warranty requirements and maintain high service quality.
The Walker Products Oxygen Sensor also complies with emissions regulations in major markets, making it suitable for both original equipment manufacturers and aftermarket applications. Its ability to deliver accurate oxygen readings supports catalytic converter efficiency, helping vehicles meet stringent emission standards while preserving fuel efficiency. Whether installed as a preventative maintenance part or as a corrective repair, the sensor contributes to smoother engine operation and lower exhaust emissions.
