Bosch 15389 Oxygen Sensor - Downstream Right

Bosch Actual OE Oxygen Sensor for Sentra

Bosch Part Number 15389 is a specific-fit, narrow-band heated oxygen sensor for select Nissan Sentra applications. It is built to deliver accurate air-fuel-ratio feedback to the ECU, helping maintain stable closed-loop fuel control and lower emissions in normal driving conditions.

For 2001-2002 Nissan Sentra downstream right applications, Bosch 15389 matches the OE-style sensor layout with a 4-wire harness, square male connector, and threaded mounting design.

Key Features

• Specific-fit Bosch Actual OE Oxygen Sensor
• Narrow-band heated oxygen sensor for precise lambda feedback
• 4-wire design with included wiring harness
• Square male connector and blade terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing for high-temperature and vibration resistance
• Wiring harness length: 26 in; overall length: 29.7 in

Product Details

Bosch developed its oxygen sensor technology from early OE designs and later planar narrowband formats that improve light-off speed, closed-loop response, and measurement accuracy. This Bosch Actual OE Oxygen Sensor uses advanced ceramic elements and controlled heater operation to provide consistent signal output under demanding exhaust temperatures. It is a direct replacement for select Nissan Sentra downstream right locations and is listed for 2001 late production and 2002 models, excluding SULEV applications. This part number is 15389.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Symptoms It Can Address

• Check engine light related to oxygen sensor performance
• Incorrect fuel trim readings from the downstream sensor
• Rough or unstable closed-loop fuel control
• Emissions test failure tied to sensor response
• Slow sensor switching or degraded exhaust feedback

Installation Notes and Tips

Install Bosch 15389 in the downstream right position only for the listed Nissan Sentra applications. Confirm the vehicle is not equipped with SULEV before ordering. Inspect the connector shape, terminal count, thread size, and harness length against the original sensor before installation. Use proper oxygen sensor service tools on the 22 mm hex and verify the threaded bung is clean and undamaged.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Part Number 15389 reflects Bosch’s Actual OE line for accurate replacement performance in the specified Nissan Sentra fitments.
