Bosch 15375 Oxygen Sensor - Upstream

Bosch Wideband Oxygen Sensor for Jaguar

Bosch Validated Oxygen Sensor 15375 is a specific-fit wideband A/F oxygen sensor built for precise air-fuel ratio monitoring in select Jaguar applications. It uses a heated, 4-wire design with a square female connector and included wiring harness for direct replacement service.

For Jaguar XF, XFR, XJ8, XJR, XK, XKR, S-Type, Super V8, and Vanden Plas applications, this Bosch oxygen sensor supports accurate upstream mixture feedback across the full lambda range. Bosch 15375 is engineered for threaded installation and OE-style fitment where a wideband sensor is required.

Key Features

• Wideband A/F oxygen sensor for continuous air-fuel ratio measurement
• Heated design for faster sensor activity after startup
• Specific-fit replacement with included wiring harness
• 4-wire configuration with square female connector
• Threaded mounting, 18 mm thread size, 22 mm hex
• Metal housing with robust ceramic sensor construction
• Bosch Validated Oxygen Sensor line for OE-style replacement applications

Product Details

Bosch part number 15375 is a wide band oxygen sensor that provides the ECU with detailed feedback for fuel control, idle quality, and emissions management. Unlike a switching sensor, a wideband sensor measures across the full lambda range, giving the engine management system more precise data during load changes, acceleration, and steady cruising. Bosch developed the planar pump-cell wideband design used in modern engine control systems, and this sensor reflects that OE-focused engineering approach.

This part cross-references C2P8810 for the same application. It is a direct-fit oxygen sensor for 2005-2011 Jaguar upstream locations, including 2011 Jaguar XF upstream with green connector to chassis # R47153 and 2011 Jaguar XFR upstream with green connector to chassis # R47153.

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Incorrect air-fuel ratio readings
• Rough idle or inconsistent engine response tied to mixture control
• Reduced fuel economy caused by inaccurate sensor feedback
• Emissions test failures linked to oxygen sensor faults

Installation Notes

Install Bosch 15375 in the upstream threaded sensor location specified for the vehicle. Verify connector style, harness routing, and chassis breakpoints before installation, especially on 2011 Jaguar XF and XFR models with the green connector note. Confirm the 18 mm thread size and 4-wire configuration match the original sensor before replacement.

Compatible With 2005-2011 Jaguar XF, XFR, XJ8, XJR, XK, XKR, S-Type, Super V8, and Vanden Plas upstream applications as listed in the fitment data.
