Bosch 13514 Oxygen Sensor - Upstream

Bosch Wideband Oxygen Sensor for Volvo

Bosch Validated Oxygen Sensor 13514 is a specific-fit wideband air-fuel ratio sensor for select Volvo applications. It delivers continuous, high-precision AFR feedback to the engine control unit, helping maintain accurate mixture control in changing load and temperature conditions.

Fits 2005-2006 Volvo S40, Upstream. Fits 2005-2006 Volvo V50, Upstream. This Bosch Validated Oxygen Sensor 13514 is built for direct replacement service on these vehicles.

Key Features

• Wideband A/F oxygen sensor for precise air-fuel ratio measurement across the full lambda range
• Heated design for faster sensor activity and stable operation
• Specific fit with 4-wire configuration and included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Rectangle connector with male terminal and male connector gender
• Metal housing for durable underhood and exhaust-stream service
• Overall length: 28.3 in; sealing surface to connector end: 27.2 in

Product Details

Bosch 13514 uses wideband sensor technology to provide the ECU with more detailed feedback than a traditional switching oxygen sensor. Bosch pioneered the planar pump-cell wideband design used in modern engine management, and this sensor reflects that OE development history with fast light-off, controlled heater performance, and robust ceramic construction. For Volvo S40 and Volvo V50 upstream sensor replacement, Bosch 13514 supports accurate fuel control and emissions monitoring in normal driving, acceleration, and rapid load changes.

This part cross-references URO 30651722 for the same application.

Common Issues This Sensor Can Help Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn wideband sensor
• Rough idle or inconsistent throttle response caused by poor mixture control
• Reduced fuel economy from inaccurate exhaust feedback
• Elevated emissions from delayed or unstable sensor response

Installation Notes and Tips

Install Bosch 13514 in the upstream exhaust location specified for the vehicle. Verify connector shape, terminal count, thread size, and harness length before installation. Use proper oxygen sensor service tools and follow the vehicle service procedure for routing the harness away from heat and moving components.

Quality Assurance

Bosch draws on more than five decades of OE sensor development, and this Validated Oxygen Sensor line is built to OE-proven standards for accuracy and durability in aftermarket service.
