Delphi ES10456 Oxygen Sensor

Delphi ES10456 Oxygen Sensor Overview

The Delphi ES10456 is a heated oxygen sensor built for precise exhaust monitoring on a range of Nissan and INFINITI applications. With OE heritage behind the design, this sensor supports accurate air-fuel feedback for vehicles such as the Nissan Frontier, Xterra, Pathfinder, Sentra, and INFINITI Q45.

Use the ES10456 when you need a direct-fit oxygen sensor for front, rear, left, right, or upstream positions listed in the application data. The flat connector, 3-wire layout, and 18 x 1.5 mm thread size make it a practical replacement for many import vehicle exhaust systems.

Key Features

• Heated oxygen sensor for faster operating temperature and signal response
• 3-wire design with flat connector shape
• 18 x 1.5 mm thread size for common exhaust bung applications
• Overall length: 450.0
• Package contents: oxygen sensor and instruction sheet
• OE-based engineering from Delphi, backed by a century of original equipment experience

Detailed Description

Delphi ES10456 is an emission control oxygen sensor engineered for vehicles that rely on accurate exhaust oxygen measurement to manage fuel delivery and emissions performance. It is listed for multiple positions, including front, front left, front right, left, rear, right, and upstream, so the exact placement should be confirmed against the vehicle application tab before ordering. This part cross-references Bosch (e.g., 13224, 13262) for the same application.

Compatible With 1999-2004 Nissan Frontier, front right; 2000-2004 Nissan Xterra, front right; 1996-2000 Nissan Pathfinder, front right; 1997-1999 Nissan Sentra, front; and 1990-1995 INFINITI Q45, left. It also covers additional Nissan and INFINITI applications across the 1985-2004 model years, including select California-emissions configurations.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect fuel trim readings from a worn upstream sensor
• Slow sensor response during closed-loop operation
• Emissions test failures tied to exhaust feedback issues
• Rough idle or drivability concerns caused by inaccurate air-fuel data

Installation Notes and Tips

Confirm the exact position on your vehicle before installation, since this part is listed for multiple locations. Match the connector shape, wire count, and thread size to the original sensor, and verify the application notes for California-emissions or build-date-specific coverage where shown. For best results, inspect the exhaust bung threads and wiring routing before final tightening.

Quality Assurance

Delphi builds this sensor using OE experience and supplier knowledge developed over decades of original equipment production. That OE heritage is reflected in the design and application coverage of the ES10456.
