Walker 350-341102 Oxygen Sensor - Downstream
OE Replacement Oxygen Sensor for Volkswagen
Walker OE Replacement oxygen sensor part number 350-341102 is a specific-fit, heated narrow-band sensor built for downstream applications. It is engineered for vehicles that rely on accurate exhaust feedback to help the ECU monitor air-fuel control and emissions performance.
Key Features
- Specific-fit downstream oxygen sensor for Volkswagen applications
- Heated narrow-band design for standard replacement use
- 4-wire layout with 4 terminals
- Female connector with oblong shape
- Threaded mounting with M18 x 1.5 thread size
- 22 mm wrench size and 770 mm overall length
Product Details
Walker OE Replacement part number 350-341102 is designed as a direct replacement oxygen sensor for select Volkswagen Passat, Beetle, and Jetta models in downstream positions. This sensor provides the diagnostic feedback the ECU uses to monitor exhaust conditions after the catalytic converter, helping maintain proper emissions system operation. Walker Products has focused on engine management and oxygen/air-fuel sensors since 1946, and this OE Replacement line is built around application-specific fitment and sensor position.
This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Check engine or malfunction indicator light related to oxygen sensor performance
- Poor engine operation caused by inaccurate exhaust feedback
- Increased fuel consumption from incorrect air-fuel correction
- Higher exhaust emissions from a failing downstream sensor
- Fault codes stored in the ECU for sensor or related system issues
Installation Notes and Tips
Compatible With 2014-2022 Volkswagen Passat, downstream; 2014-2019 Volkswagen Beetle, downstream; 2013-2018 Volkswagen Jetta, downstream; and 2013 Volkswagen Beetle, downstream with Tier 2 emissions. Before replacement, inspect the sensor wiring harness and connector for physical damage, since damaged wiring can shorten sensor life and affect operation. Confirm the threaded mounting, connector style, and downstream location before installation.
Quality Assurance
Walker Products manufactures engine management sensors as OE-style replacement parts for specific vehicle applications and positions. The brand operates under ISO 9001/TS 16949 quality systems and has supplied automotive sensor and fuel system components since 1946.
