Bosch 17047 Oxygen Sensor - Upstream

Bosch Wideband O2 Sensor for OE Fitment

Bosch 17047 is an Actual OE Oxygen Sensor built as a wideband air-fuel sensor for precise upstream mixture monitoring. It delivers continuous lambda-range measurement for accurate ECU fuel control on select Hyundai, Kia, and Volkswagen applications, including Hyundai Accent, Kia Rio, Kia Soul, Hyundai Veloster, and Volkswagen Jetta.

Key Features

• Wideband A/F oxygen sensor for detailed air-fuel ratio feedback
• Heated design for faster sensor warm-up and stable operation
• Specific-fit replacement with threaded mounting
• 5-wire harness with male connector and blade terminals
• Metal housing with robust ceramic sensor construction
• OE-style replacement for upstream sensor locations
• Bosch part number 17047 for direct catalog lookup

Product Details

Bosch’s Actual OE Oxygen Sensor line is based on the company’s long-running OE development work in engine management. This wideband sensor uses a planar pump-cell design to provide the ECU with more detailed feedback than a traditional switching sensor, helping maintain accurate fuel delivery across changing load and temperature conditions. Bosch 17047 is a threaded, heated, specific-fit upstream oxygen sensor with an oblong male connector, 18 mm thread size, and included wiring harness. It is listed for 2015-2017 Hyundai Accent, 2016-2017 Hyundai Veloster, 2015-2017 Kia Rio, 2014-2016 Kia Soul, and 2013-2016 Volkswagen Jetta.

This part cross-references Bosch 17047 for the same application.

Common Replacement Reasons

• Check engine light related to oxygen sensor performance
• Rough idle or inconsistent air-fuel control
• Reduced fuel economy from inaccurate upstream sensor readings
• Emissions test failure tied to sensor response issues
• Slow sensor switching or heater circuit faults

Installation Notes

Install in the upstream position only where specified by the vehicle application. Verify the 18 mm thread size, 22 mm hex, connector shape, wire count, and harness length before installation. Because this is a specific-fit sensor, match the connector and routing to the original unit on the vehicle. Use proper oxygen sensor service tools and follow factory torque and wiring procedures.

Quality Assurance

Bosch supplies OE-proven oxygen sensor technology to the aftermarket, with wideband sensing, optimized heater control, and durable construction for consistent operation under thermal cycling and rapid load changes.
