Bosch 15462 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Oxygen Sensor for Mitsubishi Applications

Bosch Engineered Oxygen Sensor 15462 is a narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management in Mitsubishi applications that require a specific-fit, threaded replacement sensor.

Key Features

• Bosch Engineered Oxygen Sensor line with OE-focused design and application coverage
• Narrow-band heated oxygen sensor for closed-loop fuel control
• Specific fit with square connector, 4-wire layout, and male blade terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 23.3 in harness length and 27 in overall length
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions

Detailed Description

This Bosch 15462 oxygen sensor uses a switching-type narrow-band design to send accurate exhaust oxygen readings to the ECU. Bosch developed this sensor family from its original thimble-style O2 sensor platform and later planar narrowband designs, focusing on faster light-off, quicker closed-loop operation, and improved lambda accuracy. For Mitsubishi Outlander, Mitsubishi Eclipse, Mitsubishi Galant, and Mitsubishi Montero applications, Bosch 15462 provides a direct replacement format with the correct connector style and threaded mount.

Bosch Engineered Oxygen Sensor products are built with advanced ceramic elements, optimized heater control, and materials selected to withstand heat and vibration in the exhaust stream. This part cross-references Mitsubishi OE numbers such as MD369190 and MR578081 for the same application.

Vehicle Fitment

• Fits 2013 Mitsubishi Outlander, Upstream Rear.
• Fits 2007-2012 Mitsubishi Outlander, Upstream Right.
• Fits 2011-2012 Mitsubishi Eclipse, Upstream; Cylinder(s) 3 and 4.
• Fits 2007-2010 Mitsubishi Eclipse, Upstream; Cylinder(s) 1 and 2.

What It Helps Address

• Fault codes related to oxygen sensor response or heater circuit performance
• Rough idle caused by inaccurate air-fuel feedback
• Reduced fuel control accuracy during closed-loop operation
• Elevated emissions from a worn upstream sensor
• Delayed sensor switching after exhaust heat-up

Installation Notes and Tips

Confirm the sensor position, connector shape, wire count, and thread size before installation. This Bosch 15462 uses a threaded 18 mm mount and a square male connector, so matching the original harness and exhaust bung is important for proper fit on Mitsubishi Eclipse, Galant, Outlander, and Montero applications. Inspect the exhaust threads and connector routing before tightening the sensor into place.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development in engine management and emissions sensing. The Bosch Engineered Oxygen Sensor line is built to OE-style standards for accurate signal output, durable heater performance, and consistent operation under thermal and vibration load.
