Bosch 13418 Oxygen Sensor - Upstream

Bosch OE Oxygen Sensor for Nissan

Bosch 13418 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 select Nissan Pathfinder, Pickup, and D21 applications.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated design for faster closed-loop operation
• Specific fit with threaded mounting and 18 mm thread size
• 3-wire harness with oblong male connector and blade terminals
• Metal housing with high-temperature-resistant construction
• Wiring harness included; harness length measures 69.1 in
• Upstream sensor position for listed Nissan applications

Product Details

Bosch 13418 uses a switching-type narrow-band design to measure oxygen content and relay accurate feedback to the engine control unit. Bosch developed this sensor family from its original OE oxygen sensor work and later planar narrowband technology, focusing on quicker light-off, improved lambda accuracy, and faster transition into closed-loop control. For drivers servicing a Nissan Pathfinder, Nissan Pickup, or Nissan D21, this sensor provides the OE-style signal behavior expected by the vehicle calibration.

This part cross-references 2269075P01 for the same application.

Vehicle Fitment

• Fits 1994-1995 Nissan Pathfinder, upstream.
• Fits 1995 Nissan Pickup, upstream.
• Fits 1994 Nissan D21, upstream.

Common Issues This Sensor May Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim conditions caused by inaccurate exhaust feedback
• Slow closed-loop response during warm-up or steady cruising
• Emissions test failures tied to a worn upstream O2 sensor
• Rough idle or drivability concerns linked to faulty air-fuel ratio sensing

Installation Notes and Tips

Confirm the upstream sensor location before ordering and match the connector, thread diameter, and harness length to the original part. Use the correct 22 mm hex size during removal and installation, and inspect the exhaust bung threads for damage before threading in the new sensor. Because this is a specific-fit replacement, verify the vehicle year, model, and position against the listed applications for Bosch 13418.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and this replacement follows the same OE-proven engineering approach used by vehicle manufacturers. Bosch 13418 is built for consistent signal accuracy and durable operation under heat and vibration.
