Bosch 15373 Oxygen Sensor - Downstream

Bosch Validated Oxygen Sensor for Jaguar

Bosch Validated Oxygen Sensor 15373 is a narrow-band heated downstream O2 sensor built for precise air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management across changing operating conditions in Jaguar applications.

Key Features

• Specific-fit oxygen sensor for direct replacement use
• Narrow-band heated sensor design for faster closed-loop operation
• 4-wire harness with rectangular female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included for a cleaner service replacement
• Metal housing and high-temperature materials for demanding exhaust environments

Product Details

Bosch 15373 is part of the Bosch Validated Oxygen Sensor line, which builds on Bosch OE development in oxygen sensing technology. This downstream sensor uses a switching-type narrow-band design with optimized heater control and ceramic sensing elements to deliver accurate lambda feedback after the catalyst. It is a direct-fit replacement for Jaguar XF, XFR, XJ8, XJR, XK, XKR, S-Type, Super V8, and Vanden Plas applications listed below. This part cross-references C2C22679 for the same application.

Installation Notes

Verify the downstream sensor location, connector shape, wire count, and chassis breakpoints before installation. The threaded 18 mm sensor body and 4-wire harness should match the original equipment layout on the vehicle. Confirm the connector routing and harness length during replacement to avoid strain on the lead.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, and the Validated Oxygen Sensor line is built to OE-proven standards for accuracy, durability, and consistent heater performance in harsh thermal and vibration conditions.
