Walker OE Replacement Oxygen Sensor 350-64143
Walker OE Replacement oxygen sensor part number 350-64143 is a specific-fit, heated wide-band sensor built for direct replacement in select Nissan and INFINITI applications. It is engineered to provide the ECU with the diagnostic feedback needed for accurate air-fuel control, emissions monitoring, and drivability.
Key Features
- Heated wide-band oxygen sensor for precise exhaust feedback
- Specific-fit design for the listed upstream positions
- 4-wire configuration with blade terminals and rectangular connector
- Threaded mounting with M18 x 1.5 thread size
- 425 mm overall length and harness length
- 22 mm wrench size for service access
Product Details
Walker Products OE Replacement sensors are built as application-specific replacements for vehicles that rely on accurate oxygen and air-fuel ratio data. Part number 350-64143 is designed for upstream sensor locations and supports ECU monitoring on vehicles such as the Nissan Altima, Nissan Pathfinder, Nissan Murano, Nissan Maxima, Nissan Armada, Nissan TITAN, Nissan TITAN XD, and INFINITI QX50, QX55, QX60, and QX80. This sensor line is part of Walker Products Engine Management and Oxygen/Air-Fuel sensor coverage, developed for fitment position, connector style, and diagnostic output requirements.
This part cross-references no listed aftermarket part numbers for the same application.
Common Symptoms Addressed
- Check engine light or malfunction indicator light related to oxygen sensor performance
- Poor engine operation caused by incorrect air-fuel feedback
- Increased fuel consumption from inaccurate exhaust sensing
- Elevated exhaust emissions from a failing upstream sensor
- Fault codes stored in the ECU for sensor or related system faults
