Spectra OS6119 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Spectra OS6119 Oxygen Sensor for Nissan and INFINITI

The Spectra OS6119 oxygen sensor is an OE-style replacement for downstream applications on select Nissan and INFINITI vehicles. It is built with engineering, manufacturing, and quality control standards aimed at matching the performance of the original sensor it replaces.

Key Features

• Downstream oxygen sensor for emissions system monitoring
• Direct replacement for select Bank 1 Sensor 2 and Bank 2 Sensor 2 applications
• Fits multiple Nissan 370Z, Nissan Juke, and INFINITI models
• OE-style construction for factory-style signal response
• Part number OS6119 for easy identification

Detailed Description

Use the Spectra OS6119 when replacing a downstream oxygen sensor on vehicles such as the 2014-2018 INFINITI Q70, 2015-2017 INFINITI QX50, 2014-2017 Nissan 370Z, and 2011-2015 Nissan Juke. This sensor supports emissions control by monitoring exhaust oxygen content after the catalytic converter, helping the engine control system maintain proper fuel management and emissions performance. This part cross-references Four Seasons 24167 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect oxygen sensor readings from a worn sensor
• Emissions test failures tied to sensor performance
• Fuel trim issues caused by inaccurate exhaust feedback
• Replacement needs for Bank 1 Sensor 2 or Bank 2 Sensor 2 locations

Installation Notes and Tips

Confirm the vehicle year, make, model, and sensor position before ordering.
