Bosch 15410 Oxygen Sensor - Downstream

Bosch Oxygen Sensor for Downstream Applications

Bosch Engineered Oxygen Sensor 15410 is a specific-fit, narrow-band heated O2 sensor built for accurate air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management in downstream applications for select Acura and Honda models.

Compatible With 2004-2008 Acura TSX downstream, 2004-2007 Honda Accord downstream with California Emission System, and 2003 Honda Accord downstream, Japan Built. Bosch 15410 is a direct replacement choice for drivers searching for a downstream oxygen sensor for Acura TSX or Honda Accord emissions repair.

Key Features

• Specific-fit Bosch Engineered Oxygen Sensor
• Narrow-band heated oxygen sensor design
• 4-wire configuration with blade terminals
• Threaded mounting with 18 mm thread diameter
• Rectangle female connector with wiring harness included
• Overall length: 41.3 in; harness length: 37.6 in
• Standard replacement grade for OE-style service
• Metal housing with high-temperature-resistant construction

Product Details

Bosch 15410 uses a switching-type narrow-band design to provide the ECU with precise oxygen-content feedback during closed-loop operation. Bosch developed this sensor line from its long-running OE oxygen sensor engineering, including planar narrowband technology that improves light-off response and lambda accuracy. The result is consistent signal control under heat, vibration, and demanding exhaust conditions.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. For buyers comparing Bosch 15410 against other downstream oxygen sensor options, the part number 15410 is the key identifier for this Bosch Engineered Oxygen Sensor.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel mixture readings from the downstream sensor
• Reduced emissions performance during inspection
• Slow or unstable closed-loop fuel control
• Faulty sensor response from heat- or vibration-related wear

Installation Notes

Install in the downstream exhaust location only where listed in the fitment data. Verify the 18 mm threaded bung, 4-wire connector style, and harness routing before installation. The sensor uses a female rectangle connector and blade terminals, so matching the connector and wire layout is important for proper fitment on Acura TSX and Honda Accord applications.

For fitment searches, Bosch 15410 is a downstream oxygen sensor for 2004-2008 Acura TSX and 2004-2007 Honda Accord with California Emission System, plus 2003 Honda Accord Japan Built downstream applications.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development behind this product line. Bosch Engineered Oxygen Sensor parts are built to OE-proven standards for accurate signal delivery, durable materials, and reliable operation in demanding exhaust environments.
