Walker 350-341022 Oxygen Sensor - Center, Downstream or Upstream

OE Replacement Oxygen Sensor for Volkswagen

Walker OE Replacement oxygen sensor 350-341022 is a direct-fit, specific-application sensor built for vehicles that require narrow-band feedback to the ECU. It is a heated, 4-wire sensor with a D-shaped female connector and M18 x 1.5 thread size for the listed Volkswagen applications.

Compatible With 2013 Volkswagen Jetta, center; 2013-2016 Volkswagen Beetle, downstream; and 2016-2017 Volkswagen CrossFox, upstream. If you are diagnosing a check engine light, poor fuel economy, or elevated emissions on a Volkswagen Beetle, Jetta, or CrossFox, this sensor is built for the exact position shown in the fitment data.

Product Details

Walker Products develops engine management and oxygen/air-fuel sensors as OE-style replacements for many vehicle platforms worldwide. The 350-341022 is engineered for the listed position and vehicle application so the ECU receives the correct sensor signal for emissions and fuel-control monitoring. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

For Volkswagen Jetta, Volkswagen Beetle, and Volkswagen CrossFox applications, this sensor is the correct choice when the original narrow-band oxygen sensor has aged, contaminated, or failed electrically. The Walker OE Replacement line focuses on direct-fit sensor service for modern engine management systems.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor circuit or response faults
• Rough running caused by inaccurate exhaust oxygen feedback
• Increased fuel consumption from incorrect air-fuel correction
• Higher exhaust emissions from a degraded sensor signal
• Fault codes stored in the ECU for the affected sensor position

Installation Notes

Verify the exact vehicle, engine, and sensor position before ordering. This part is specific to the listed upstream, downstream, or center locations shown in the fitment data. Inspect the sensor wiring harness, connector, and surrounding exhaust components for heat damage or corrosion before installation, since damaged wiring can shorten sensor life and affect diagnosis.

Use the correct 22 mm oxygen sensor tool and confirm the M18 x 1.5 thread engagement during installation. Clear stored fault codes after repair and confirm the ECU returns to normal sensor feedback.

Quality Assurance

Walker Products has supplied engine management components since 1946 and manufactures to ISO 9001 / TS 16949 quality standards. The OE Replacement line is built for application-specific fitment and diagnostic system feedback on the listed Volkswagen models.
