Bosch 13262 Oxygen Sensor - Upstream or Upstream Right

Bosch Actual OE Oxygen Sensor 13262

Bosch 13262 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 specific Nissan and INFINITI applications, including 1998-1999 Nissan Sentra upstream, 1998 Nissan 200SX upstream, and 1997 INFINITI Q45 upstream right.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated O2 sensor for closed-loop fuel control
• Specific fit design with 3-wire harness and male blade terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Wiring harness included with 12 in harness length and 15.7 in overall length

Detailed Description

Bosch 13262 uses a switching-type narrow-band design to report oxygen content in the exhaust stream so the engine control unit can adjust fueling accurately. Bosch developed this sensor family from its long OE oxygen sensor experience, including planar narrowband technology that improves light-off response, lambda accuracy, and closed-loop operation. For drivers searching for a Bosch 13262 oxygen sensor for 1998-1999 Nissan Sentra upstream or a Bosch 13262 replacement for 1997 INFINITI Q45 upstream right, this part matches the listed applications and mounting requirements.

This part cross-references 226904M201 and 226906P101 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim concerns caused by inaccurate exhaust feedback
• Slow closed-loop response after startup
• Emissions test failures tied to sensor degradation
• Rough combustion control from a worn upstream O2 sensor

Installation Notes and Tips

Verify the connector shape, 3-wire configuration, and threaded mounting before installation. Use the listed upstream position only for the confirmed applications, and confirm thread size, hex size, and harness routing match the original sensor. Because this is a specific-fit sensor, compare the vehicle’s original connector and exhaust location before replacement.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development behind this part. The sensor uses advanced ceramic elements, optimized heater control, and heat-resistant materials to maintain consistent signal quality under thermal and vibration load.
