Bosch 13822 Oxygen Sensor

Bosch Oxygen Sensor for Mitsubishi Applications

Bosch Part Number 13822 is a narrow-band heated oxygen sensor built for specific Mitsubishi applications that require accurate air-fuel-ratio feedback to the ECU. It is a direct-fit, threaded replacement with a square male connector, 4-wire harness, and OE-style construction for stable closed-loop operation.

Key Features

• Bosch Engineered Oxygen Sensor, Part Number 13822
• Narrow-band heated O2 sensor for precise exhaust feedback
• Specific fit replacement with threaded mounting
• 4-wire design with included wiring harness
• Square connector, male terminal and connector configuration
• Metal housing with high-temperature-resistant construction
• 22 mm hex size and 18 mm thread diameter

Product Details

Bosch Engineered Oxygen Sensor 13822 uses a switching-type narrow-band design to measure exhaust oxygen content and send accurate signals to the engine control unit. Bosch developed this sensor line from its long OE oxygen sensor experience, including faster light-off and improved closed-loop response through advanced ceramic elements and optimized heater control. For Mitsubishi Endeavor, Galant, Diamante, Montero, Montero Sport, and 3000GT applications, this sensor is built to match the original mounting and electrical interface.

This part cross-references Mitsubishi OE numbers MD312083 and MD330259 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the ECU
• Rough idle or unstable combustion control
• Reduced fuel economy caused by inaccurate exhaust readings
• Emissions test failures tied to a worn downstream or upstream sensor

Installation Notes and Fitment

Fits 2011 Mitsubishi Endeavor, downstream left. Fits 2010 Mitsubishi Endeavor, downstream front. Fits 2004-2008 Mitsubishi Endeavor, downstream front. Fits 2009 Mitsubishi Galant, downstream front. Fits 2004-2007 Mitsubishi Galant, downstream front. Fits 2001-2004 Mitsubishi Diamante, downstream left. Fits 2004 Mitsubishi Montero Sport, downstream right. Fits 1999-2000 Mitsubishi Diamante, downstream left, with California Emission System. Fits 1996-2000 Mitsubishi Montero, downstream right, with California Emission System. Fits 1997-2000 Mitsubishi Montero Sport, upstream, without California Emission System. Fits 1997 Mitsubishi 3000GT, downstream left.

Before installation, confirm the sensor position, connector shape, thread size, and harness routing against the original unit. Use the correct oxygen sensor socket and avoid contaminating the sensing element during handling. Bosch Part Number 13822 is a direct replacement for the listed Mitsubishi fitments and is designed to restore proper sensor response when the original unit has aged or failed.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development experience. The design uses durable materials, heater control, and ceramic sensing technology developed for consistent operation under heat and vibration in everyday driving.
