Bosch 15965 Oxygen Sensor - Downstream Right

Bosch OE Oxygen Sensor for Nissan Sentra

Bosch 15965 is a narrow-band heated oxygen sensor built for precise air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management for select Nissan Sentra applications, including downstream right placement.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated oxygen sensor for closed-loop fuel control
• Specific fit design for direct application matching
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire configuration with square male connector and blade terminals
• Wiring harness included with 26 in harness length
• Metal housing with high-temperature-resistant construction

Product Details

Bosch 15965 uses a switching-type narrow-band design to deliver accurate oxygen content feedback to the engine control unit. Bosch developed this sensor family from its original OE oxygen sensor technology and later planar narrowband designs, focusing on faster light-off, quicker closed-loop operation, and consistent lambda accuracy. For Nissan Sentra owners, this sensor is a direct-fit replacement for the downstream right position on 2000 and 2001 models, including 2001 Nissan Sentra early production and excluding SULEV applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Slow closed-loop response after sensor aging
• Emissions test failures tied to sensor degradation
• Rough combustion control caused by inaccurate exhaust readings

Installation Notes and Tips

Fits 2000 Nissan Sentra, downstream right, except Super Ultra Low Emission Vehicle (SULEV). Fits 2001 Nissan Sentra, downstream right, early production; except Super Ultra Low Emission Vehicle (SULEV). Confirm the connector shape, wire count, and threaded mounting location before installation. Use the correct oxygen sensor socket for the 22 mm hex and verify the harness routing keeps the lead away from heat and moving components.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Bosch 15965 reflects that OE-focused engineering for accurate signal response and durable operation in demanding thermal and vibration conditions.
