Bosch 17011 Oxygen Sensor - Upstream

Bosch Wideband O2 Sensor for OE-Style Control

Bosch Actual OE Oxygen Sensor 17011 is a wideband air-fuel sensor built for precise mixture feedback and stable engine management. It delivers fast response, heated operation, and direct-fit compatibility for select Hyundai, Kia, and Saab applications.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement across the full lambda range
• Heated design for faster light-off and more consistent readings during cold starts
• Specific-fit sensor with 5-wire harness and 6 terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with included wiring harness
• Robust metal housing for OE-style durability in high-heat exhaust locations
• Bosch part number 17011 for direct catalog lookup

Detailed Description

Bosch 17011 is an Actual OE Oxygen Sensor from Bosch’s wideband A/F sensor line, engineered to provide the ECU with detailed air-fuel ratio data instead of the simpler switching signal used by traditional sensors. That level of feedback supports accurate fuel control under changing load, temperature, and driving conditions. Bosch pioneered the planar pump-cell wideband design used in modern engine management, and this sensor reflects that OE development background.

This part is a direct-fit upstream oxygen sensor for 2012-2015 Hyundai Veloster, 2012-2014 Hyundai Accent, 2012-2014 Kia Rio, 2012-2013 Kia Soul, and 2006-2009 Saab 9-3. If you are searching for a Bosch 17011 oxygen sensor for a Hyundai Veloster upstream location or a Kia Rio upstream wideband O2 sensor, this listing matches those applications. This part cross-references 392102B210 and 93185453 for the same application.

What It Helps Address

• Check engine lights related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the ECU
• Rough idle or drivability issues tied to mixture control
• Reduced fuel economy caused by inaccurate exhaust feedback
• Emissions test failures linked to a worn upstream sensor

Installation Notes and Tips

Install this sensor in the upstream position only where listed in the fitment data. Confirm connector shape, terminal count, thread size, and harness length before installation. Because this is a wideband sensor, proper connector matching and secure routing away from exhaust heat are important for reliable operation. Use the vehicle’s service information for torque and wiring procedures.

Quality Assurance

Bosch supplies OE-level oxygen sensors backed by more than five decades of engine-management development. Bosch 17011 is built to OE specifications for accurate signal output, fast response, and dependable performance in demanding exhaust environments.
