Product Details
Walker Products OE focuses on original-equipment replacement sensors for engine management systems. Part number 250-54036 is designed around the required fitment position and sensor feedback needs of the vehicle ECU, making it a direct replacement choice for emissions and drivability service. This part number 250-54036 is listed for 2009-2010 Nissan Murano upstream front and upstream rear positions, as well as 2008 INFINITI G37 upstream left and upstream right positions. Walker Products OE 250-54036 supports the sensor locations used on these applications, including the Nissan Murano exhaust system and the INFINITI G37 upstream sensor positions.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Poor engine operation caused by incorrect exhaust feedback
- Increased fuel consumption from inaccurate air-fuel readings
- Higher exhaust emissions from a failing heated O2 sensor
- Stored ECU fault codes tied to the affected sensor circuit
Installation Notes and Tips
Confirm the exact position before installation: Fits 2009-2010 Nissan Murano, upstream front; Fits 2009-2010 Nissan Murano, upstream rear; Fits 2008 INFINITI G37, upstream left; Fits 2008 INFINITI G37, upstream right. Inspect the sensor, wiring harness, and connector for heat damage, abrasion, or corrosion before replacement. Verify thread size, connector shape, and harness routing against the original part to ensure proper installation and ECU feedback.
Quality Assurance
Walker Products has produced engine management and oxygen sensor components since 1946 and operates as an ISO 9001 / TS 16949 certified manufacturer. The Walker Products OE line is built as an OE-style replacement range for specific applications, with attention to fitment position and diagnostic system requirements.
