Product Details

Bosch developed the original wideband planar pump-cell oxygen sensor design used in modern engine management systems. The Bosch Actual OE Oxygen Sensor line focuses on OE-proven sensor technology, giving the ECU the detailed lambda information needed for accurate fuel delivery and emissions control. Part Number 17034 follows that OE-style approach with robust ceramic construction, optimized heater control, and fast light-off characteristics for stable operation during changing load and temperature conditions.

This part cross-references 9202153 for the same application.

Common Symptoms This Sensor Can Address

• Check engine light related to oxygen sensor or air-fuel ratio faults
• Rough idle or inconsistent fuel trim readings
• Poor fuel economy caused by inaccurate mixture feedback
• Reduced engine response during acceleration
• Emissions test failure tied to sensor performance

Installation Notes

Compatible With 2000-2001 Volvo S80, upstream left. Verify connector shape, terminal count, thread size, and harness routing before installation. Use the correct oxygen sensor socket for the 22 mm hex and confirm the sensor seats fully on the threaded mount. Inspect the wiring path and connector lock before clearing fault codes and completing a relearn or drive cycle if required by the vehicle.

Quality Assurance

Bosch backs this sensor with more than five decades of OE development in oxygen sensing and engine management technology. Bosch Part Number 17034 is built to OE-level specifications for accurate signal output and dependable service in the listed Volvo S80 applications.
