Bosch 17169 Oxygen Sensor - Upstream or Upstream Right

Bosch Wideband OE Oxygen Sensor

Bosch 17169 is an Actual OE Oxygen Sensor built as a wideband air-fuel sensor for precise mixture feedback to the ECU. It is a specific-fit, heated replacement with a 5-wire harness and 6-terminal layout for direct service on select Audi, Porsche, Volkswagen, and Hyundai 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 stable operation during cold starts
• Specific-fit replacement with included wiring harness
• 18 mm thread diameter, 22 mm hex size, threaded mounting
• Oblong male connector with male blade terminals
• Metal housing with robust ceramic sensor construction
• Overall length: 22.0 in; sealing surface to connector end: 20.9 in

Product Details

Bosch 17169 uses wideband sensor technology to provide the ECU with detailed air-fuel ratio data instead of the on/off style signal used by traditional switching sensors. That level of feedback supports accurate fuel control, smoother engine operation, and lower emissions under changing load conditions. Bosch’s Actual OE Oxygen Sensor line reflects decades of OE development, and this part follows the same wideband architecture Bosch introduced for modern engine management systems. This Bosch 17169 oxygen sensor is a direct service choice for vehicles such as the Audi Q3, Porsche Cayenne, and Volkswagen Tiguan where upstream mixture control is critical.

This part cross-references 06E906262K and 06J906262M for the same application.

What It Helps Address

• Fault codes related to upstream air-fuel ratio sensor performance
• Rough idle or inconsistent fuel trim readings
• Reduced fuel economy caused by inaccurate mixture feedback
• Emissions test failures tied to sensor response issues
• Driveability concerns during cold start or rapid throttle changes

Installation Notes and Tips

Confirm the connector shape, terminal count, thread size, and upstream position before installation. This Bosch 17169 oxygen sensor is a specific-fit, threaded sensor with an included harness, so routing and connector alignment should match the original layout. Use proper oxygen sensor service tools and follow the vehicle service procedure for torque and wiring handling. Verify the application by year, make, model, and position before ordering.

Quality Assurance

Bosch supplies OE-developed oxygen sensors to the aftermarket, and the Actual OE Oxygen Sensor line is built to OE-proven specifications for accurate signal control and durable operation in demanding thermal conditions.
