Bosch 16567 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Bosch Validated Oxygen Sensor for Nissan and INFINITI

Bosch 16567 is a narrow-band heated oxygen sensor built for specific downstream applications on select Nissan and INFINITI vehicles. It provides the ECU with accurate air-fuel-ratio feedback to support stable combustion control and lower emissions during normal driving.

The Bosch Validated Oxygen Sensor line reflects Bosch OE development experience and focuses on durable, accurate replacement sensors for vehicles that rely on precise closed-loop operation. Part number 16567 is a direct-fit style replacement with the correct connector, harness length, and threaded mounting design for the listed applications.

Key Features

• Specific-fit Bosch oxygen sensor for downstream locations
• Narrow-band heated design for faster closed-loop response
• 4-wire configuration with included wiring harness
• Rectangle female connector with pin terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction
• Overall length: 19.9 in; sealing surface to connector end: 18.7 in

Detailed Description

Bosch 16567 uses a switching-type narrow-band sensor element to measure exhaust oxygen content and send precise feedback to the engine control unit. That signal helps the system maintain the proper air-fuel ratio, which is important for emissions control, drivability, and consistent combustion performance. Bosch’s validated oxygen sensor design draws on decades of OE development, including advanced ceramic elements and heater control strategies that improve sensor response in demanding thermal and vibration conditions.

This part cross-references Nissan 226A03NT0A for the same application. It is a strong match for drivers searching for a downstream oxygen sensor for 2013-2014 Nissan Altima, 2012-2014 Nissan Murano, 2012-2014 Nissan Quest, 2013-2014 Nissan Pathfinder, 2013 INFINITI JX35, 2014-2015 INFINITI QX60, and 2013-2021 Nissan NV200 applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Slow or unstable closed-loop fuel control
• Emissions test failures tied to sensor response issues
• Rough combustion behavior caused by a worn downstream sensor

Installation Notes and Tips

Verify the connector shape, wire count, thread size, and downstream position before installation. This Bosch 16567 sensor is a specific-fit replacement, so matching the vehicle application and sensor location is essential. Inspect the exhaust bung threads and wiring routing before tightening the sensor to the specified threaded mount.

For fitment, this part is listed for 2020-2021 Nissan NV200, downstream; 2013-2019 Nissan NV200, downstream; 2015 INFINITI QX60, downstream right; 2014 INFINITI QX60, downstream right; 2013-2014 Nissan Altima, downstream left; 2012-2014 Nissan Murano, downstream right and downstream; 2013-2014 Nissan Pathfinder, downstream right; 2012-2014 Nissan Quest, downstream right; and 2013 INFINITI JX35, downstream right.
