Bosch 13387 Oxygen Sensor - Upstream

Bosch Validated Oxygen Sensor for Nissan Maxima

Bosch Validated Oxygen Sensor 13387 is a specific-fit, narrow-band heated O2 sensor for precise air-fuel-ratio feedback to the ECU. It is built for stable combustion control and emissions management in the 1990-1994 Nissan Maxima, upstream position.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated sensor design for closed-loop fuel control
• Blade terminals with oblong connector and included wiring harness
• Threaded mounting with 12 mm thread diameter and 17 mm hex size
• Metal housing and high-temperature-resistant construction for demanding engine bay conditions
• Wiring harness length: 69 in; overall length: 72 in

Product Line Details

Bosch Validated Oxygen Sensor parts are backed by Bosch OE development experience and reflect the company’s long history in oxygen sensor design. Bosch introduced early thimble-style sensors and later refined planar narrowband technology to improve light-off response, lambda accuracy, and closed-loop operation. Part number 13387 carries that OE-focused approach into the aftermarket for the Nissan Maxima.

Detailed Description

Bosch 13387 is a standard replacement oxygen sensor engineered to deliver accurate exhaust oxygen feedback so the engine control unit can adjust fuel delivery in real time. For 1990-1994 Nissan Maxima upstream service, this narrow-band heated sensor helps maintain stable combustion control, supports emissions performance, and restores proper sensor response when the original unit has aged or become contaminated. This part cross-references Nissan OE number 2269098E00 for the same application.

Common Issues It Can Help Resolve

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel control
• Increased fuel consumption from inaccurate exhaust feedback
• Slow closed-loop transition after warm-up
• Emissions test failure caused by a worn upstream sensor

Installation Notes and Tips

Fits 1990-1994 Nissan Maxima, upstream. Verify the threaded bung size, connector shape, and harness routing before installation. Use the correct 17 mm oxygen sensor socket and inspect the exhaust threads for damage or corrosion. Because this is a heated narrow-band sensor, confirm the vehicle’s wiring and connector condition are in good repair before final assembly.

Quality Assurance

Bosch draws on more than five decades of oxygen sensor development and OE supply experience. Bosch 13387 is built to OE-proven standards for accurate signal output, thermal durability, and consistent operation under vibration and heat.
