Delphi ES10384 Oxygen Sensor - Front Left, Front Right or Left

OE Oxygen Sensor for Nissan and Infiniti

Delphi ES10384 is a heated oxygen sensor built for precise exhaust feedback in select Nissan and Infiniti applications. It uses OE-based engineering from a supplier with long-standing original equipment experience, helping maintain accurate air-fuel control and emissions performance.

Key Features

• Heated oxygen sensor for faster operating temperature and stable signal output
• 3-wire design with a flat connector shape
• 18 x 1.5 mm thread size for direct-thread installation
• Overall length: 755.0
• Includes oxygen sensor and instruction sheet
• Position-specific coverage for front left, front right, and left applications

Detailed Description

The Delphi ES10384 oxygen sensor is engineered for vehicles that rely on accurate exhaust monitoring to manage fuel delivery and emissions. This part number, ES10384, is listed for 1995-1999 Nissan Maxima, 1996-1998 Infiniti I30, and 1995-1997 Infiniti J30 applications, including front left and front right positions where specified. It also cross-references Bosch 13505 and DENSO Auto Parts 234-3098 for the same application.

Built with Delphi’s OE heritage and manufacturing knowledge, ES10384 is a practical replacement choice when the original sensor is slow to respond, contaminated, or no longer providing consistent feedback. For fitment-specific use, verify the exact position on your vehicle before ordering. This part is a direct-fit oxygen sensor for Nissan Maxima and Infiniti I30/J30 models within the listed years.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate exhaust feedback
• Reduced fuel economy from improper air-fuel mixture control
• Failed emissions testing tied to sensor response issues
• Slow sensor switching or degraded signal output

Installation Notes and Tips

Confirm the vehicle’s exact year, model, and sensor position before installation. This sensor uses a 3-wire heated design with a flat connector and 18 x 1.5 mm thread size, so connector style and mounting location should match the original unit. For the listed applications, verify whether your vehicle is front left, front right, or left position specific, and check notes such as the 1999 Infiniti I30 and 1999 Nissan Maxima without California Emission System.

Quality Assurance

Delphi draws on 100 years of OE experience and original equipment supply knowledge, with that background reflected in the design of this aftermarket oxygen sensor. The ES10384 is built to align with OE-style fitment and performance expectations for the listed Nissan and Infiniti applications.
