Bosch 15380 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Wideband O2 Sensor for Nissan and Infiniti

Bosch Validated Oxygen Sensor 15380 is a specific-fit, heated wideband air-fuel ratio sensor built for precise upstream monitoring. It delivers fast response and detailed lambda measurement to help the engine control unit manage fuel delivery, performance, and emissions more accurately.

For drivers searching for a Bosch oxygen sensor for Nissan Altima, Sentra, Rogue, Frontier, or Infiniti QX56 applications, this part number 15380 matches a wide range of upstream locations across select 2007-2012 vehicles.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated design for faster sensor warm-up and stable operation
• Specific-fit replacement with included wiring harness
• 4-wire configuration with square male connector and blade terminals
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Robust metal housing for standard replacement use
• Overall length: 16.1 in; harness length: 12.7 in

Product Details

Bosch pioneered the wideband A/F oxygen sensor design used in modern engine management systems, and this Bosch Validated Oxygen Sensor follows that OE-focused approach. The sensor provides continuous feedback across the full lambda range, giving the ECU more detailed information than a traditional switching O2 sensor. That makes Bosch 15380 a direct-fit choice for upstream air-fuel ratio control on select Nissan and Infiniti models, including Altima, Sentra, Rogue, Frontier, Armada, Pathfinder, Xterra, Maxima, Versa, Cube, 350Z, Titan, G35, and QX56 applications.

This part cross-references Nissan/Infiniti OE numbers such as 22693ET000 and 22693JA00B for the same application.

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn wideband sensor
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough idle, hesitation, or drivability issues tied to sensor response
• Emission test failures linked to faulty air-fuel monitoring

Installation Notes and Tips

Fits 2007-2011 Nissan Altima, upstream; 2007-2011 Nissan Versa, upstream; 2008-2010 Nissan Rogue, upstream without California Emission System; and other listed upstream Nissan and Infiniti applications. Confirm the connector shape, wire count, thread size, and upstream position before installation. Use proper oxygen sensor service tools and inspect the exhaust bung threads for damage before threading in the new sensor.

Quality Assurance

Bosch backs this sensor with more than five decades of OE development in oxygen sensing and engine management. Part number 15380 is built as a standard replacement with OE-proven design principles for accurate, durable operation.
