Bosch 13482 Oxygen Sensor - Upstream

Bosch Actual OE Oxygen Sensor for Nissan

Bosch 13482 is a specific-fit, narrow-band heated oxygen sensor built for upstream applications on select Nissan models. It provides air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate combustion management, and lower emissions.

As part of Bosch’s Actual OE Oxygen Sensor line, this sensor reflects Bosch’s long-running OE development in oxygen sensing technology, including faster light-off and improved lambda accuracy in narrowband designs. For drivers searching for a Bosch 13482 oxygen sensor for Nissan Altima or Nissan Pickup upstream replacement, this part matches the original application requirements.

Key Features

• Specific-fit oxygen sensor for confirmed Nissan applications
• Narrow-band heated sensor design for upstream use
• 3-wire configuration with included wiring harness
• Threaded mounting with 18 mm thread size and 22 mm hex
• Oblong male connector with blade terminals
• Metal housing built for high-temperature and vibration exposure
• Standard replacement grade for OE-style service

Product Details

Bosch 13482 is a switching-type oxygen sensor that measures exhaust oxygen content and sends precise feedback to the engine control unit. That signal helps the ECU maintain the correct air-fuel ratio during closed-loop operation, which supports smoother combustion control and emissions performance. The heated narrow-band design helps the sensor reach operating temperature quickly and maintain consistent response across changing load and temperature conditions.

This part cross-references Hyundai/Kia 226905E401 for the same application. Fits 1997-1999 Nissan Altima, upstream; fits 1997 Nissan Pickup, upstream; fits 1996 Nissan Altima, upstream; fits 1996 Nissan Pickup, upstream.

Common Problems This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel control
• Reduced fuel control accuracy during closed-loop operation
• Failed emissions inspection caused by a worn upstream sensor
• Slow sensor response from age, heat, or contamination

Installation Notes and Tips

Verify the upstream location before installation and confirm the connector style, thread diameter, and harness length match the original sensor. The threaded mounting design uses an 18 mm thread and 22 mm hex, so the correct oxygen sensor socket or wrench is recommended. Inspect the harness routing and connector condition before final connection to avoid strain or heat damage.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development in sensor technology. The Actual OE Oxygen Sensor line is built to deliver OE-proven fit, response, and durability for aftermarket replacement.
