Bosch 13377 Oxygen Sensor - Upstream

Bosch Oxygen Sensor for Honda Applications

Bosch Part Number 13377 is a specific-fit, narrow-band heated oxygen sensor built for upstream placement on select Honda vehicles. It provides air-fuel-ratio feedback to the ECU for stable closed-loop fuel control and lower emissions.

Compatible With 2000-2002 Honda Accord, 2001-2004 Honda Odyssey, and 2001-2005 Honda Civic, this Bosch Engineered Oxygen Sensor is a direct replacement for the listed upstream applications. The Bosch 13377 uses a threaded mounting design, 4-wire blade terminals, and a rectangular male connector with included wiring harness for a clean OE-style connection.

• Specific-fit oxygen sensor for listed Honda upstream applications
• Narrow-band heated sensor design for closed-loop fuel control
• Threaded mounting with 18 mm thread size and 22 mm hex
• 4-wire configuration with blade terminals and male connector
• Metal housing with high-temperature-resistant construction
• Wiring harness included for the listed application
• Bosch Part Number 13377

Product Details

Bosch Engineered Oxygen Sensor products draw on Bosch OE development in oxygen sensing technology, including narrowband designs that improve response time and help the ECU maintain accurate mixture control. This Bosch 13377 is a standard replacement sensor with heated operation, a threaded mount, and a specific fit for upstream locations on the Honda Accord, Honda Odyssey, and Honda Civic listed above. It is built for consistent signal output under heat and vibration, making it a practical replacement when the original sensor is slow, contaminated, or no longer reporting accurately. This part cross-references Honda OE numbers 36531P8CA21 and 36531P8FA11 for the same application.

Common Issues This Part Can Address

• Check engine light related to oxygen sensor performance
• Rough idle or unstable air-fuel mixture control
• Reduced fuel economy from inaccurate upstream sensor readings
• Failed emissions inspection caused by sensor response issues
• Delayed closed-loop operation after startup

Installation Notes and Tips

Install Bosch 13377 only in the listed upstream positions for the confirmed Honda applications. Verify connector shape, wire count, thread size, and harness routing before installation. Because oxygen sensors are exposed to high heat, use proper removal tools and inspect the exhaust threads and connector condition before fitting the replacement sensor.

Quality Assurance

Bosch has decades of OE oxygen sensor development behind this Engineered Oxygen Sensor line, with designs focused on accurate signal output, heater control, and durability in demanding exhaust environments. Part Number 13377 is built to Bosch standard replacement specifications for the listed fitments.
