Bosch 13322 Oxygen Sensor - Downstream or Upstream

Bosch Oxygen Sensor for Honda Applications

Bosch Part Number 13322 is a specific-fit, 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 Honda applications, including 1999-2001 Honda Odyssey downstream and 1992-1996 Honda Prelude upstream.

Key Features

• Bosch Engineered Oxygen Sensor line with OE development heritage
• Narrow-band heated O2 sensor for closed-loop fuel control
• Specific-fit design with 4-wire harness and rectangular female connector
• Threaded mounting with 18 mm thread size and 22 mm hex
• Wiring harness included; harness length measures 11.6 in.
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions

Product Details

Bosch 13322 is a standard replacement oxygen sensor that measures exhaust oxygen content and sends accurate feedback to the engine control unit. Bosch’s oxygen sensor program evolved from its original thimble-style design to planar narrowband technology, improving light-off response, lambda accuracy, and closed-loop operation. This Bosch Engineered Oxygen Sensor is built for consistent signal output under heat and vibration, making it a direct service part for Honda Odyssey and Honda Prelude applications that require a narrow-band heated sensor.

This part cross-references Honda OE numbers 36531P5K003 and 36531P12A12 for the same application.

Vehicle Fitment

• Fits 1999-2001 Honda Odyssey, downstream.
• Fits 1992-1996 Honda Prelude, upstream.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel control
• Delayed closed-loop fuel correction after startup
• Increased exhaust emissions from inaccurate sensor feedback
• Poor fuel trim response caused by a worn upstream or downstream sensor

Installation Notes

Confirm the sensor position before ordering, since Bosch 13322 is listed for upstream and downstream locations on different Honda models. Verify the 4-wire connector, threaded mounting style, and 18 mm thread size against the original part. Use proper oxygen sensor service tools and follow factory torque specifications during installation.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and this Bosch Engineered Oxygen Sensor is built to the same type of engineering standards used by vehicle manufacturers. The design emphasizes accurate lambda measurement, reliable heater performance, and durability in high-temperature exhaust environments.
