Bosch 17228 Oxygen Sensor - Upstream

Bosch Wideband O2 Sensor for Porsche Cayenne

Bosch 17228 is an Actual OE oxygen sensor built as a specific-fit wideband air-fuel sensor for the upstream position on select Porsche Cayenne models. It provides the ECU with continuous air-fuel ratio data for precise mixture control, helping maintain stable drivability, fuel efficiency, and emissions performance.

Key Features

• Wideband A/F oxygen sensor for continuous lambda-range measurement
• Heated design for faster sensor warm-up and quicker closed-loop operation
• Specific-fit replacement with a 5-wire harness and included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with blade terminals and 6 terminal positions
• Metal housing with robust ceramic sensor construction for OE-style durability
• Overall length: 58.1 in; sealing surface to connector end: 56.9 in

Product Details

Bosch pioneered the wideband A/F oxygen sensor design used in modern engine management, and the Bosch Actual OE Oxygen Sensor line carries that OE development into the aftermarket. Part number 17228 is engineered for accurate upstream air-fuel measurement on 2008-2010 Porsche Cayenne applications, giving the engine control unit detailed feedback across changing load and temperature conditions. This Bosch 17228 sensor is a direct replacement choice for drivers servicing a Porsche Cayenne upstream oxygen sensor circuit with a wideband, heated, specific-fit design.

This part cross-references Porsche 94860613102 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to upstream oxygen sensor faults
• Erratic air-fuel ratio readings from a worn wideband sensor
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough idle, hesitation, or inconsistent throttle response
• Emissions test failures tied to oxygen sensor performance

Installation Notes

Fits 2008-2010 Porsche Cayenne, upstream. Confirm connector shape, wire count, thread size, and sensor position before installation. Use the correct oxygen sensor socket for the 22 mm hex, and inspect the harness routing to avoid heat damage or strain on the connector. Because this is a specific-fit Bosch 17228 sensor, match the original upstream location and electrical connection before clearing fault codes.

Quality Assurance

Bosch supplies OE-level oxygen sensor technology backed by more than five decades of original equipment development. The Actual OE Oxygen Sensor line reflects Bosch’s long-standing role in wideband sensor engineering and modern emissions control.
