Bosch 15822 Oxygen Sensor - Downstream or Downstream Left

Bosch Validated Oxygen Sensor for Volvo and Land Rover

Bosch Validated Oxygen Sensor 15822 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 monitoring in a range of operating conditions for select Volvo and Land Rover applications.

With a threaded metal housing, 4-wire design, and included wiring harness, this Bosch oxygen sensor is a direct-fit replacement for specific downstream locations, including Volvo S60, XC60, XC70, S80, V60, V70, C30, S40, and V50, plus Land Rover LR2, LR4, Range Rover, and Range Rover Sport applications.

Key Features

• Bosch Validated Oxygen Sensor line for OE-style replacement fitment
• Part number 15822 for downstream oxygen sensor applications
• Narrow-band heated sensor for faster closed-loop operation
• 4-wire configuration with blade terminals and rectangular connector
• Threaded 18 mm mounting with 22 mm hex size
• Specific-fit design with wiring harness included
• Metal housing built for high-temperature and vibration exposure

How Bosch Validated Oxygen Sensor 15822 Works

Bosch 15822 measures exhaust oxygen content and sends a switching-type signal to the engine control unit so fuel delivery can be adjusted accurately. Bosch’s oxygen sensor development has evolved from early thimble-style designs to planar narrowband technology, improving light-off speed, lambda accuracy, and closed-loop response. For drivers servicing a Volvo XC60 downstream oxygen sensor or a Land Rover LR4 downstream left oxygen sensor, this part provides the OE-proven sensor architecture expected in emissions control service.

This part cross-references Land Rover LR005793 and Volvo 30774569 for the same application.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Slow sensor response during closed-loop operation
• Emissions test failures tied to oxygen sensor faults
• Rough combustion control caused by aging O2 sensor output
