Bosch OE Oxygen Sensor for Volvo 850
Bosch 13517 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It is a specific-fit replacement for the upstream position on 1993-1994 Volvo 850 models listed for the air pump application.
Key Features
- Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
- Narrow-band heated design for closed-loop fuel control
- Threaded mounting with 18 mm thread diameter and 22 mm hex size
- 4-wire configuration with blade terminals and included wiring harness
- Metal housing with high-temperature-resistant construction
- Specific fit for the upstream location on Volvo 850 applications
Product Details
Bosch 13517 uses a switching-type sensing element to measure exhaust oxygen content and send accurate feedback to the engine control unit. Bosch developed this sensor family from its original OE oxygen sensor designs and later planar narrowband technology, focusing on faster light-off, improved lambda accuracy, and quicker closed-loop operation. For 1993-1994 Volvo 850 vehicles, this Bosch oxygen sensor supports stable combustion control and consistent emissions performance in the upstream position.
This part cross-references 1271576 for the same application.
What It Helps Address
- Check engine light related to oxygen sensor performance
- Rough idle caused by inaccurate air-fuel mixture feedback
- Increased fuel consumption from delayed closed-loop correction
- Emissions test failure tied to a worn upstream sensor
- Slow sensor response during warm-up or steady-state driving
Installation Notes
Verify the threaded mounting, 4-wire connector, and upstream location before installation. The sensor includes the wiring harness and uses a male oblong connector with blade terminals. Confirm the 18 mm thread size and 22 mm hex size match the original sensor on your Volvo 850 before removal.
Quality Assurance
Bosch has more than five decades of OE oxygen sensor development and supplies aftermarket sensors built to OE-proven standards. Bosch 13517 is engineered for durable operation under heat and vibration, with materials selected for demanding exhaust environments.
