Bosch 13071 Oxygen Sensor - Downstream, Downstream Rear or Upstream

Bosch Oxygen Sensor for Honda and Acura

Bosch 13071 is a narrow-band heated oxygen sensor built for specific vehicle applications that require accurate air-fuel feedback to the ECU. It is engineered for stable combustion control, quicker closed-loop response, and consistent emissions monitoring across changing operating conditions.

Compatible With 1996-2005 Honda and Acura applications including Honda Accord, Prelude, Odyssey, Isuzu Oasis, Acura NSX, Acura CL, and Acura TL in the listed upstream or downstream positions.

Key Features

• Bosch Engineered Oxygen Sensor line with OE-focused design and calibration
• Narrow-band heated oxygen sensor for faster light-off and closed-loop operation
• Specific-fit replacement with a 4-wire harness and rectangular female connector
• Threaded mounting design with 18 mm thread size and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Wiring harness included for direct replacement on listed applications

Detailed Description

Bosch 13071 uses a switching-type narrow-band sensing element to measure exhaust oxygen content and send precise air-fuel-ratio data to the engine control unit. That feedback helps the ECU maintain proper mixture control on vehicles such as the Honda Accord, Honda Prelude, Honda Odyssey, Acura NSX, Acura CL, and Acura TL. The Bosch Engineered Oxygen Sensor line draws on Bosch OE development history, including advanced ceramic elements and optimized heater control for reliable operation under heat and vibration.

This part cross-references Honda/Acura OE numbers such as 36531P5P014 and 36532P5MA02 for the same application. Bosch 13071 is a direct-fit service part for downstream and upstream positions listed in the fitment data, including Honda Accord downstream and Honda Prelude upstream applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture readings reported by the ECU
• Slow sensor response during closed-loop operation
• Emissions test failures tied to faulty O2 sensor output
• Rough idle or drivability issues caused by inaccurate exhaust feedback

Installation Notes and Tips

Verify the exact year, make, model, and sensor position before ordering. This Bosch 13071 uses a threaded mount, 4-wire configuration, and rectangular female connector, so match the connector style and harness length to the original sensor on the vehicle. For best results, inspect the exhaust bung threads and wiring routing before installation, and confirm the application is listed as upstream or downstream as shown in the fitment data.
