Bosch 17035 Oxygen Sensor - Upstream Right

Bosch Wideband O2 Sensor for Volvo S80

Bosch Part Number 17035 is an Actual OE Oxygen Sensor built for precise air-fuel ratio monitoring in wideband applications. It is a specific-fit, heated sensor for the upstream right position on select 2000-2001 Volvo S80 models, with OE-style signal accuracy and a direct replacement design.

Key Features

• Wideband A/F oxygen sensor for continuous lambda measurement
• Specific fit for the upstream right location
• Heated design for faster sensor response
• 5-wire harness with included wiring harness
• Threaded mounting with 18 mm thread diameter
• Rectangle connector, male terminal configuration
• Metal housing with robust ceramic sensor construction
• Overall length: 53.1 in; sealing surface to connector end: 52 in

Product Details

Bosch 17035 uses wideband sensing technology to provide the ECU with detailed air-fuel ratio data across the full lambda range. That level of feedback supports accurate mixture control during idle, cruise, acceleration, and load changes. Bosch pioneered the planar pump-cell wideband design, and this Actual OE Oxygen Sensor reflects that OE development history in a direct-fit aftermarket replacement.

Compatible with 2000-2001 Volvo S80, upstream right, Bosch 17035 is a practical choice when the original sensor is slow to respond, sets mixture-related fault codes, or no longer delivers stable readings. This part cross-references 9470570 for the same application.

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn wideband sensor
• Rough idle or hesitation caused by inaccurate mixture feedback
• Reduced fuel economy from poor ECU fuel control
• Emissions test failure tied to sensor response or signal quality

Installation Notes and Tips

Verify the upstream right location before installation on your Volvo S80. The sensor uses a threaded mount with a 22 mm hex size and a 6-terminal connector layout; confirm connector shape, wire routing, and harness length against the original part before removal. Because this is a heated wideband sensor, avoid contaminating the sensing element during handling and follow the vehicle service procedure for connector and exhaust access.

Quality Assurance

Bosch supplies OE-proven oxygen sensor technology backed by more than five decades of engine management development. Bosch 17035 is built to the same standard expected from an Actual OE Oxygen Sensor, with durable construction and precise signal output for modern emission control systems.
