Bosch 15515 Oxygen Sensor

Bosch Validated Oxygen Sensor for OE-Style Control

Bosch Validated Oxygen Sensor 15515 is a specific-fit, narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It is used in Mitsubishi Eclipse, Outlander, Galant, Mirage, and select Chrysler Sebring and Dodge Stratus applications where accurate upstream or rear sensor response is required.

Key Features

• Specific-fit Bosch oxygen sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• Advanced ceramic sensing element for stable signal output
• Optimized heater control for quicker light-off
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire harness with square male connector and blade terminals
• Wiring harness included with 16.1 in harness length
• Metal housing for high-temperature and vibration resistance

Detailed Description

Bosch part number 15515 is part of the Bosch Validated Oxygen Sensor line, a product line focused on OE-style replacement coverage and application-specific fitment. Bosch has decades of oxygen sensor development behind this design, including the transition from early thimble-style sensors to planar narrowband technology that improves light-off speed, lambda accuracy, and closed-loop response. This sensor is engineered to deliver consistent switching-type O2 readings so the engine control unit can maintain stable combustion control and emissions performance.

Compatible With 2013 Mitsubishi Outlander, upstream front; 2011-2012 Mitsubishi Eclipse, upstream right; 2007-2012 Mitsubishi Outlander, upstream left; 2007-2010 Mitsubishi Eclipse, upstream rear; 2004-2009 Mitsubishi Galant, upstream rear; 2004-2005 Chrysler Sebring, upstream left; 2004-2005 Dodge Stratus, upstream right; 2004-2005 Mitsubishi Eclipse, upstream front; 2001-2002 Mitsubishi Mirage, upstream; and 1998-2000 Mitsubishi Mirage, upstream with California Emission System. This part cross-references Mitsubishi MD342323 and MN158758 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor signal faults
• Rich or lean fuel trim conditions caused by inaccurate O2 feedback
• Slow sensor response during closed-loop operation
• Emissions test failures tied to upstream or rear sensor performance
• Rough idle or unstable combustion control from degraded sensor output

Installation Notes and Tips

Verify the sensor position before ordering, since Bosch 15515 is used in upstream front, upstream right, upstream left, upstream rear, and upstream locations depending on vehicle application. Confirm the 18 mm thread size, 4-wire connector style, and harness routing before installation. Use proper oxygen sensor service tools to avoid damaging the threaded bung or wiring during removal and replacement.

Quality Assurance

Bosch oxygen sensors are backed by more than five decades of OE development and are supplied to the aftermarket with OE-proven design principles. Bosch Validated Oxygen Sensor 15515 is built for durable operation under heat and vibration while maintaining accurate signal control across a wide range of operating conditions.
