Walker 250-54130 Oxygen Sensor - Upstream
Walker OE Base Oxygen Sensor 250-54130
Walker 250-54130 is a heated wide-band oxygen sensor built as a specific-fit OE Base Sensor for select Toyota applications. It provides the ECU with the exhaust feedback needed for accurate air-fuel control, making it a direct replacement choice for upstream sensor service on the listed vehicles.
Key Features
- Heated wide-band oxygen sensor for precise exhaust monitoring
- Specific-fit design for the correct application and mounting position
- 4-wire configuration with pin terminals
- Female connector with square connector shape
- M18 x 1.5 thread size and 22 mm wrench size
- OE Base Sensor line from Walker Products
Product Details
The Walker OE Base Sensor line is engineered as an OE-style replacement for engine management systems that rely on accurate oxygen sensor feedback. Part number 250-54130 is designed for upstream placement and is listed for 2024-2026 Toyota Grand Highlander, 2022-2026 Toyota Sienna, and 2022-2025 Toyota Highlander. It is also listed for 2020-2021 Toyota Highlander, B1S1, and 2021 Toyota Sienna, B1S1. If you are searching for a Toyota Highlander upstream oxygen sensor or a Toyota Sienna upstream wide-band sensor, this application-specific part number is built around those exact fitments.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Poor engine operation caused by incorrect air-fuel feedback
- Increased fuel consumption from inaccurate exhaust readings
- Elevated exhaust emissions from a failing upstream sensor
- Fault codes stored in the ECU for the affected sensor circuit
Installation Notes
Confirm the connector shape, terminal count, thread size, and upstream position before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten sensor life and affect signal quality. For fitment-based searches, Walker 250-54130 is the correct upstream oxygen sensor for select Toyota Grand Highlander, Toyota Sienna, and Toyota Highlander applications listed above.
Quality Assurance
Walker Products manufactures engine management and oxygen/air-fuel sensors as OE replacement parts and operates as an ISO 9001/TS 16949 certified company. Since 1946, Walker Products has focused on engine management sensors and fuel system components for vehicle applications worldwide.
