Bosch 16228 Oxygen Sensor - Downstream, Downstream Left or Downstream Right

Bosch Actual OE Oxygen Sensor for Nissan and INFINITI

Bosch 16228 is an Actual OE Oxygen Sensor built as a narrow-band heated replacement for specific Nissan and INFINITI applications. It provides precise air-fuel-ratio feedback to the ECU, helping maintain stable combustion control and lower emissions across changing operating conditions.

The Bosch Actual OE Oxygen Sensor line draws on Bosch OE development dating back to the original oxygen sensor design and later planar narrowband technology. For drivers searching for a downstream oxygen sensor for Nissan Maxima, Murano, Pathfinder, Altima, Juke, or INFINITI QX60, Bosch 16228 delivers OE-style fitment and sensor response.

Key Features

• Part number 16228 Bosch Actual OE Oxygen Sensor
• Narrow-band heated oxygen sensor with threaded mounting
• Specific-fit design with 4-wire, 4-terminal blade connector
• Rectangle male connector with included wiring harness
• Metal housing with high-temperature-resistant construction
• 22 mm hex size and 18 mm thread diameter
• Downstream application coverage for select Nissan and INFINITI models

Detailed Description

Bosch 16228 uses advanced ceramic sensing elements and optimized heater control to support quicker closed-loop operation and accurate lambda measurement once the exhaust reaches operating temperature. The sensor is built for harsh thermal and vibration loads, making it a direct replacement choice for vehicles that rely on precise downstream oxygen sensor feedback. This Bosch oxygen sensor part number 16228 is a practical OE-style solution for Nissan Maxima, Nissan Murano, Nissan Pathfinder, Nissan Altima, Nissan Juke, and INFINITI QX60 applications listed below.

This part cross-references 226A04LA1B for the same application.

Vehicle Fitment

• Fits 2016-2021 Nissan Maxima, downstream right.
• Fits 2016-2020 INFINITI QX60, downstream right.
• Fits 2015-2019 Nissan Murano, downstream right.
• Fits 2015-2018 Nissan Altima, downstream left.
• Fits 2015-2018 Nissan Pathfinder, downstream right.
• Fits 2016 Nissan Juke, downstream. To 07/2016.
• Fits 2015 INFINITI QX60, downstream right. From 10/2014.
• Fits 2015 Nissan Juke, downstream. From 11/2014.

What It Helps Address

• Faulty downstream oxygen sensor readings
• Check engine light concerns related to O2 sensor performance
• Unstable air-fuel feedback control after catalyst monitoring
• Emissions test failures tied to sensor response issues
• Rough exhaust monitoring data caused by aging sensor elements

Installation Notes and Tips

Confirm the connector shape, wire count, and downstream position before installation. Bosch 16228 is a specific-fit sensor with a threaded mount, so the correct bank and side matter on Nissan and INFINITI applications. Inspect the harness routing and exhaust-thread condition during replacement, and verify the vehicle build date for 2015-2016 Juke and 2015 QX60 applications where production timing affects fitment.

Quality Assurance

Bosch backs this Actual OE Oxygen Sensor line with more than five decades of OE development and aftermarket supply experience. The sensor is built to Bosch OE standards for accuracy, durability, and consistent operation under heat and vibration.
