Bosch 13075 Oxygen Sensor - Downstream or Upstream

Bosch Oxygen Sensor for Honda Accord and Insight

Bosch Engineered Oxygen Sensor 13075 is a specific-fit, narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management for select Honda applications, including Honda Accord and Honda Insight fitments.

Key Features

• Specific-fit Bosch oxygen sensor for direct application matching
• Narrow-band heated sensor design for faster closed-loop operation
• Blade terminals with a 4-wire harness and female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing with high-temperature-resistant construction
• Wiring harness included; harness length measures 8.9 in
• Overall length: 12.2 in; sealing surface to connector end: 11 in

Product Details

Bosch 13075 is part of the Bosch Engineered Oxygen Sensor line, which builds on Bosch OE oxygen sensor development dating back to 1976. This narrow-band heated sensor uses advanced ceramic elements and optimized heater control to deliver consistent signal response across changing exhaust temperatures and vibration loads. For drivers searching for a Honda Accord upstream oxygen sensor or a Honda Insight downstream O2 sensor, Bosch 13075 provides the OE-style fit and signal behavior expected in emission control service.

This part cross-references Honda OE numbers 36531P0BA01 and 36531PAA305 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel mixture control
• Delayed closed-loop operation after startup
• Inaccurate exhaust oxygen readings sent to the ECU
• Emissions test failures tied to sensor response issues

Installation Notes

Compatible With 1994-2002 Honda Accord, upstream, and 2000-2001 Honda Insight, downstream. Verify connector shape, wire count, thread size, and sensor position before installation. Use the 18 mm hex size for removal and installation, and confirm the threaded mounting location matches the original sensor.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards for accuracy, durability, and thermal resistance.
