Product Details
Walker Products Aftermarket 350-35059 is part of the Walker Products engine management and oxygen/air-fuel sensor line, developed as an OE replacement for many vehicle applications worldwide. For the 2004 Volkswagen Touareg, upstream right oxygen sensor performance is critical because the ECU uses this signal to manage air-fuel ratio and monitor emissions system operation. Walker Products 350-35059 is built for the specified position and connector layout so the sensor can deliver the diagnostic feedback required by the vehicle control system.
This part number is also referenced as Walker Products 350-35059 for the same application. If your Touareg has a check engine light, poor fuel economy, elevated exhaust emissions, or stored fault codes related to the oxygen sensor circuit, this replacement sensor is the correct place to start.
What It Helps Address
- Check engine light related to the upstream oxygen sensor circuit
- Incorrect air-fuel ratio feedback to the ECU
- Reduced fuel economy caused by a failing sensor
- Higher exhaust emissions from inaccurate exhaust monitoring
- Poor engine performance tied to sensor signal loss
Installation Notes
Fits 2004 Volkswagen Touareg, upstream right. Confirm the connector shape, wire count, thread diameter, and harness length before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. Verify the fault code and sensor location before replacement to ensure the correct upstream right application.
Quality Assurance
Walker Products has been manufacturing engine management and fuel system components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-35059 is produced as a specific application replacement to support the diagnostic needs of the ECU on the listed vehicle.
