Bosch 13461 Oxygen Sensor - Downstream or Upstream

Bosch Actual OE Oxygen Sensor for Hyundai and Kia

Bosch Part Number 13461 is an actual OE oxygen sensor built for specific Hyundai and Kia applications. It provides narrow-band, heated switching-type air-fuel feedback to the ECU for stable closed-loop fuel control and emissions monitoring.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band heated sensor for precise switching-type signal output
• Specific fit with threaded mounting and 18 mm thread size
• 4-wire design with square female connector and pin terminals
• Wiring harness included; harness length 11.5 in
• Metal housing with high-temperature-resistant construction
• Overall length 14.8 in; sealing surface to connector end 13.7 in
• 22 mm hex size for service removal

Detailed Description

Bosch 13461 is engineered for direct replacement in select Hyundai Elantra, Accent, Tucson, Tiburon, and Kia Rio, Rio5, Soul, Sportage, Spectra, and Spectra5 applications. It uses Bosch narrow-band oxygen sensing technology to measure exhaust oxygen content and send accurate feedback to the engine control unit, helping maintain proper combustion control across changing load and temperature conditions.

The Bosch Actual OE Oxygen Sensor line builds on Bosch’s long OE development history, including early thimble-style sensors and later planar narrowband designs that improved light-off speed, lambda accuracy, and closed-loop response. For drivers searching for a Bosch 13461 oxygen sensor replacement for Hyundai Elantra downstream or a Bosch 13461 upstream oxygen sensor for Kia Rio, this part matches the listed vehicle positions and connector style.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Unstable air-fuel ratio feedback during closed-loop operation
• Slow sensor response after warm-up
• Emissions test failures tied to sensor signal degradation
• Rough combustion control caused by inaccurate exhaust oxygen readings

Installation Notes and Tips

Verify the connector shape, wire count, thread diameter, and sensor position before installation. This Bosch 13461 oxygen sensor is a specific-fit, threaded unit with a square female connector and 4-wire harness, so matching the original sensor layout is important. Use the listed fitment to confirm whether your vehicle requires an upstream or downstream sensor, including 2001-2012 Hyundai Elantra downstream, 2000-2011 Hyundai Accent upstream or downstream, and 2006-2011 Kia Rio upstream.

For service access, confirm the 22 mm hex size and route the harness away from heat and moving components. On Hyundai and Kia exhaust systems, proper connector orientation and secure harness placement help maintain signal integrity after installation.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-proven replacement backed by more than five decades of oxygen sensor development and aftermarket support. The design uses advanced ceramic elements, controlled heater operation, and heat-resistant materials for consistent performance under thermal and vibration load.
