Bosch 13727 Oxygen Sensor - Downstream

Bosch 13727 Oxygen Sensor for Nissan Pickup

Bosch 13727 is an Actual OE Oxygen Sensor built for precise air-fuel ratio feedback to the ECU. It is a narrow-band heated sensor with a threaded mount, square connector, and specific-fit wiring for direct replacement on select Nissan Pickup applications.

Key Features

• Actual OE Oxygen Sensor from Bosch
• Narrow-band heated design for closed-loop fuel control
• Specific fit for select downstream Nissan Pickup applications
• 4-wire configuration with included wiring harness
• Blade terminals, square connector, male connector and terminal ends
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Steel finish with metal housing for high-temperature service

Product Details

Bosch 13727 uses a switching-type oxygen sensing element to report exhaust oxygen content to the engine control unit, helping maintain stable combustion control and emissions performance. Bosch developed this sensor line from its OE oxygen sensor experience, including planar narrowband designs that improve light-off response, lambda accuracy, and closed-loop operation. For drivers searching for a downstream oxygen sensor for 1996-1997 Nissan Pickup, Bosch 13727 provides the OE-style configuration and connector layout needed for a direct replacement.

This part cross-references 226A01S715 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings sent to the ECU
• Rough idle or unstable fuel control from a worn downstream sensor
• Emissions test failures tied to sensor response issues
• Slow closed-loop operation after sensor aging or contamination

Installation Notes and Tips

Compatible With 1997 Nissan Pickup, downstream. Compatible With 1996 Nissan Pickup, downstream, from 01/1996. Verify connector shape, wire count, thread size, and sensor position before installation. Use the threaded mount and 18 mm sensor hex specification to match the original exhaust bung, and confirm the harness routing reaches the factory connector without strain.

Quality Assurance

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