Walker 350-64109 Oxygen Sensor - Downstream Right
OE Replacement Oxygen Sensor for Lexus LS500
Walker OE Replacement oxygen sensor 350-64109 is a specific-fit, heated wide-band sensor built for precise exhaust feedback to the ECU. It is listed for the 2023-2024 Lexus LS500 in the downstream right position, making it a direct-match option for owners replacing a failed emissions sensor on this application.
Key Features
- Walker OE Replacement line for application-specific fitment
- Part number 350-64109
- Heated wide-band oxygen sensor design
- Specific fit for the downstream right position
- 4-wire configuration with blade terminals
- Square female connector with male terminals
- Threaded M18 x 1.5 mounting
- Standard replacement grade for emissions system service
Product Details
Walker Products engineers its engine management and oxygen/air-fuel sensors as OE-style replacements for defined vehicle applications. This sensor is built for the Lexus LS500 and uses the correct connector shape, terminal layout, and mounting style to match the original downstream right sensor location. The wide-band design provides the ECU with the feedback needed for emissions control and fuel management on the specified vehicle application. If you are replacing Walker 350-64109 on a 2023-2024 Lexus LS500, this part is matched to the listed position and electrical configuration.
This part cross-references no listed aftermarket part numbers for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Poor fuel economy caused by inaccurate exhaust feedback
- Elevated exhaust emissions from a failing sensor
- Rough engine operation tied to sensor signal issues
- Fault codes stored in the ECU for the downstream right sensor circuit
Installation Notes
Confirm the vehicle is a 2023-2024 Lexus LS500 and verify the downstream right sensor location before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or physical wear, since damaged wiring can shorten sensor life and affect readings. The threaded M18 x 1.5 mounting and 4-wire blade-terminal design should be matched carefully to the original equipment layout.
Quality Assurance
Walker Products states that its engine management and oxygen sensor lines are developed as original-equipment replacement parts and manufactured under ISO 9001 / TS 16949 quality systems. Since 1946, Walker Products has focused on engine management sensors and fuel system components for vehicle applications worldwide.
