Delphi ES10959 Oxygen Sensor Overview
The Delphi ES10959 is a heated oxygen sensor built for precise exhaust feedback in select Nissan and INFINITI applications. It draws on Delphi’s OE heritage and decades of supplier experience to support accurate air-fuel monitoring in front sensor locations.
Compatible With 2000-2001 INFINITI I30, front left; 2001 INFINITI QX4, front right; 2000-2001 Nissan Maxima, front left or front right; and 2001 Nissan Pathfinder, front right. The Delphi ES10959 is a direct-fit oxygen sensor for specific front positions listed below.
Key Features
- Heated oxygen sensor for faster operating temperature
- 3-wire design with flat connector shape
- 18 x 1.5 mm thread size for the specified applications
- Overall length: 680.0
- Includes oxygen sensor and instruction sheet
- OE-based engineering from Delphi
Detailed Description
Delphi ES10959 is an emission control sensor intended for front left and front right positions on select 2000-2001 INFINITI I30 and Nissan Maxima models, plus 2001 INFINITI QX4 and 2001 Nissan Pathfinder applications noted in the fitment data. As a heated oxygen sensor, it helps the engine control system monitor exhaust oxygen content more quickly after startup, supporting proper fuel delivery and emissions management. This part number, ES10959, is built with Delphi’s OE knowledge and supplier background for consistent aftermarket replacement performance.
This part cross-references Bosch 13350 and DENSO Auto Parts 234-3110 for the same application.
What It Is Used For
- Restoring oxygen sensor signal accuracy on affected vehicles
- Addressing check engine light concerns related to sensor performance
- Supporting fuel trim correction and emissions system operation
- Replacing a worn or slow-responding front oxygen sensor
- Maintaining proper exhaust feedback on Nissan Maxima and INFINITI I30 applications
Installation Notes and Tips
Verify the exact sensor position before installation, since fitment varies by vehicle and build date. Confirm the connector shape, wire count, thread size, and sensor length against the original part before replacement. For 2001 Nissan Pathfinder, the listed application is front right to 08/2000, and 2001 INFINITI QX4 is front right except mid year emissions.
Quality Assurance
Delphi builds this oxygen sensor using OE heritage and application knowledge developed through long-term supplier experience with major automakers. That background supports a replacement part engineered to match the specified vehicle fitment and sensor requirements.
