Bosch 15967 Oxygen Sensor - Downstream Left

Bosch Actual OE Oxygen Sensor for Sentra

Bosch 15967 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for the 2000-2001 Nissan Sentra, including downstream left applications listed below.

The Bosch Actual OE Oxygen Sensor line draws on Bosch’s long OE development history, including early thimble-sensor designs and later planar narrowband technology. This sensor uses a ceramic sensing element, controlled heater operation, and high-temperature-resistant materials for consistent signal response in demanding exhaust conditions.

• Fits 2001 Nissan Sentra, downstream left, early production; except Super Ultra Low Emission Vehicle (SULEV)
• Fits 2000 Nissan Sentra, downstream left; except Super Ultra Low Emission Vehicle (SULEV)
• Bosch part number 15967 for direct replacement use
• Narrow-band heated oxygen sensor with 4-wire harness
• Specific-fit design with threaded mounting and square connector
• 18 mm thread diameter and 22 mm hex size
• Wiring harness included; 28 in harness length and 31.7 in overall length

Detailed OE-Style Signal Control

Bosch 15967 is an actual OE oxygen sensor for Nissan Sentra downstream left locations where accurate exhaust oxygen feedback is required. The sensor’s heated narrow-band design helps the ECU monitor mixture changes quickly, supporting closed-loop operation and emissions control across normal driving conditions. If you are replacing a worn Bosch 15967 on a 2000 or 2001 Nissan Sentra, this OE-style sensor matches the listed fitment and connector layout.

This part cross-references 226A05M012 for the same application.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Slow or unstable air-fuel ratio feedback
• Rough combustion control during closed-loop operation
• Emissions test failures tied to downstream sensor faults
• Connector or harness mismatch on the listed Sentra applications

Installation Notes and Tips

Confirm the vehicle is a 2000 or 2001 Nissan Sentra with the downstream left position listed in the fitment table before installation. Verify the 18 mm threaded mounting point, 4-wire connector, and square male connector shape match the original sensor. Inspect the exhaust bung and wiring routing before tightening the sensor to avoid thread damage or harness strain.

Quality Assurance

Bosch supplies this Actual OE Oxygen Sensor line with OE-proven engineering developed over decades of oxygen sensor production. The sensor uses durable materials and heater control strategies intended to maintain consistent operation under heat and vibration in exhaust service.
