Bosch 15365 Oxygen Sensor - Upstream Right

Bosch 15365 Oxygen Sensor Overview

Bosch 15365 is a specific-fit, narrow-band heated oxygen sensor built for stable air-fuel-ratio feedback to the ECU. It is a direct replacement for the upstream right position on the 2002 Nissan Sentra, except Super Ultra Low Emission Vehicle (SULEV), and it uses a threaded mounting design with a square male connector and included wiring harness.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s long OE development history in oxygen sensing technology. The design focuses on accurate lambda feedback, faster closed-loop response, and dependable operation under high heat and vibration.

• Narrow-band heated oxygen sensor for ECU air-fuel control
• 4-wire design with blade terminals and square male connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing with high-temperature-resistant construction
• Wiring harness included for direct replacement use

How Bosch Engineered Oxygen Sensors Work

Bosch Engineered Oxygen Sensor products are developed to provide precise exhaust oxygen feedback so the engine control unit can adjust fuel delivery and maintain stable combustion. This Bosch 15365 sensor uses a heated narrow-band design to reach operating temperature quickly and maintain consistent signal output across changing load and temperature conditions. For drivers and technicians servicing a 2002 Nissan Sentra oxygen sensor replacement, that means reliable upstream feedback where the ECU depends on it most.

This part cross-references 226908U000 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate air-fuel feedback
• Reduced fuel control from a slow or aging upstream sensor
• Emissions test failure tied to sensor response issues
• Closed-loop operation problems in the engine management system

Installation Notes and Tips

Confirm the vehicle is a 2002 Nissan Sentra, upstream right, and verify it is not the SULEV application before ordering. The sensor uses an 18 mm thread size and threaded mounting, so proper oxygen sensor removal tools and anti-seize practices should follow the vehicle service procedure. Match the square connector and 4-wire harness routing to the original layout before final installation.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development experience. The sensor is built with advanced ceramic elements, optimized heater control, and durable materials selected for demanding thermal and vibration conditions.
