Bosch 15286 Oxygen Sensor - Upstream

Bosch Wideband Oxygen Sensor for Acura and Honda

Bosch Validated Oxygen Sensor 15286 is a specific-fit wideband air-fuel ratio sensor built for precise upstream exhaust monitoring. It provides the ECU with continuous AFR data across the full lambda range, helping maintain accurate mixture control in real-world driving.

Fits 2013-2015 Acura ILX, Upstream. Fits 2007-2009 Honda CR-V, Upstream. Bosch 15286 is a direct replacement option for drivers searching for an upstream wideband O2 sensor for Acura ILX or Honda CR-V applications.

Key Features

• Wideband air-fuel ratio sensor for continuous measurement across the full lambda range
• Heated design for faster sensor activation and stable operation
• Specific-fit replacement with 4-wire configuration
• Rectangle female connector with included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Robust metal housing for underbody exhaust environments
• Bosch Validated Oxygen Sensor line backed by Bosch OE development experience

Product Details

Bosch part number 15286 uses wideband sensor technology to deliver more detailed exhaust feedback than a traditional switching oxygen sensor. That added precision helps the engine control module manage air-fuel ratio more accurately during idle, acceleration, and load changes. The Bosch Validated Oxygen Sensor line reflects Bosch’s long OE engineering background and its role in developing the planar pump-cell wideband design used in modern engine management.

This sensor is a standard replacement choice for 2013-2015 Acura ILX upstream applications and 2007-2009 Honda CR-V upstream applications. If you are replacing a failing upstream air-fuel sensor on an Acura ILX or Honda CR-V, Bosch 15286 provides the correct fitment profile and connector style for those vehicles.

This part cross-references Honda 36531R3AG01 and 36531RZA013 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor or air-fuel ratio sensor faults
• Rough idle caused by inaccurate exhaust feedback
• Poor fuel economy from incorrect mixture control
• Hesitation or uneven throttle response during load changes
• Emissions test failures tied to upstream sensor performance

Installation Notes and Tips

Install Bosch 15286 in the upstream exhaust location specified for the vehicle application. Confirm the connector shape, terminal count, and thread size before installation, and inspect the harness routing to avoid heat damage or strain. Because this is a wideband sensor, proper electrical connection and correct placement are important for accurate ECU feedback.

Quality Assurance

Bosch develops oxygen sensor technology for OE applications and supplies aftermarket replacements built to the same engineering standards used in modern engine management systems. Bosch 15286 is part of the Bosch Validated Oxygen Sensor line, which emphasizes accurate measurement, fast response, and durable construction for emission-control service.
