Bosch 13897 Oxygen Sensor - Downstream Left or Downstream Right

Bosch Oxygen Sensor for Nissan and Suzuki

Bosch 13897 is a specific-fit, narrow-band heated oxygen sensor built for downstream right and downstream left applications on select Nissan and Suzuki vehicles. It uses a 4-wire design, square connector, and threaded mounting to deliver accurate air-fuel-ratio feedback to the ECU for stable closed-loop operation.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s long OE development history in oxygen sensing technology. The design uses advanced ceramic elements, optimized heater control, and high-temperature-resistant materials to maintain consistent signal quality under heat and vibration.

Key Features

Product Details

Bosch 13897 is engineered for vehicles that rely on a narrow-band heated oxygen sensor to monitor exhaust oxygen content after the catalytic converter. By sending precise feedback to the ECU, it supports stable combustion control and emissions management across changing operating conditions. This Bosch Engineered Oxygen Sensor line is built around OE-proven sensor architecture, including fast heater response and durable materials for demanding underbody environments. This part cross-references Nissan 226A0EA210 and 1821382Z30 for the same application.

Common Issues This Sensor Can Address

• Fault codes related to oxygen sensor response or signal range
• Rough idle or unstable fuel control caused by inaccurate exhaust feedback
• Increased emissions from a worn downstream oxygen sensor
• Delayed closed-loop operation after sensor aging or heater degradation
• Driveability concerns on Nissan Pathfinder, Frontier, Xterra, and NV van applications

Installation Notes and Tips

Confirm the downstream right or downstream left position before installation, since Bosch 13897 is position-specific. Match the connector shape, wire count, and thread size to the original sensor, and inspect the exhaust bung threads before tightening the new sensor. For best results, clear any stored diagnostic trouble codes after installation and verify sensor operation with a scan tool.

Quality Assurance

Bosch has more than five decades of oxygen sensor development experience and supplies OE-level sensor technology to the aftermarket. Bosch 13897 is built as a standard replacement part using materials and heater control strategies developed for consistent performance in demanding exhaust conditions.
