Walker 350-34485 Oxygen Sensor - Downstream

Walker 350-34485 Oxygen Sensor for Saturn

Walker Products 350-34485 is a heated oxygen sensor built as a specific-fit OE replacement for select Saturn models. It is engineered for downstream bank 1 sensor 2 locations and is intended to deliver the diagnostic feedback the ECU expects on 2000-2001 Saturn applications.

Key Features

• Heated oxygen sensor for downstream monitoring
• Specific-fit design for the listed Saturn applications
• 4-wire configuration with 20-gauge wiring
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon male connector for application-specific fitment
• Wiring harness length: 25.12 in.; overall length: 28.66 in.

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE-style replacement use. Part number 350-34485 is built for the downstream position on select Saturn L100, L200, LW200, LS, LS1, and LW1 models, where accurate exhaust feedback helps the ECU monitor catalyst and emissions performance. If the sensor signal is degraded, the vehicle may store fault codes, run poorly, increase fuel consumption, raise exhaust emissions, or illuminate the MIL.

This part cross-references no listed interchange numbers in the provided data. For Saturn LS, Saturn LS1, and Saturn LW1 owners searching for a downstream oxygen sensor replacement, Walker 350-34485 provides an application-specific option matched to the original sensor location.

Vehicle Fitment

• Fits 2001 Saturn L100, downstream bank 1 sensor 2.
• Fits 2001 Saturn L200, downstream bank 1 sensor 2.
• Fits 2001 Saturn LW200, downstream bank 1 sensor 2.
• Fits 2000 Saturn LS, downstream bank 1 sensor 2.
• Fits 2000 Saturn LS1, downstream bank 1 sensor 2.
• Fits 2000 Saturn LW1, downstream bank 1 sensor 2.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Fault codes stored by the ECU for sensor or emissions-system issues
• Poor engine operation caused by inaccurate exhaust feedback
• Higher fuel consumption from incorrect air-fuel monitoring
• Increased exhaust emissions from a worn sensor

Installation Notes

Confirm the downstream bank 1 sensor 2 location 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 threaded mounting point and connector shape match the original configuration on the vehicle.

Quality Assurance

Walker Products manufactures this sensor as an OE-style replacement for specific vehicle applications and supports it with ISO 9001/TS 16949 certified manufacturing practices. The Walker Products Aftermarket line is built around application-specific engine management components for accurate ECU feedback.
