Bosch 15360 Oxygen Sensor - Downstream

Bosch Oxygen Sensor for Mitsubishi Lancer

Bosch Part Number 15360 is a specific-fit, narrow-band heated oxygen sensor for downstream applications on select Mitsubishi Lancer models. It monitors exhaust oxygen content and sends air-fuel-ratio data to the ECU to support stable combustion control and emissions management.

Built under the Bosch Engineered Oxygen Sensor line, this replacement uses a threaded metal housing, a 4-wire harness, and a female oblong connector for a direct-style service replacement. Bosch’s OE development background is reflected in the sensor’s ceramic element design, heater control, and high-temperature materials for consistent signal output in demanding exhaust conditions.

Key Features

• Bosch Engineered Oxygen Sensor, Part Number 15360
• Narrow-band heated O2 sensor for downstream exhaust placement
• Specific fit for select Mitsubishi Lancer applications
• 4-wire design with included wiring harness
• Threaded mounting with 18 mm thread size and 22 mm hex
• Female oblong connector with pin terminals
• Metal housing for durability in high-heat environments

Application Details

Compatible With 2002-2005 Mitsubishi Lancer, downstream, and 2006 Mitsubishi Lancer, downstream, to 02/2006. Bosch 15360 is built for drivers searching for a downstream oxygen sensor for Mitsubishi Lancer 2002-2006, or a Bosch oxygen sensor replacement for Mitsubishi Lancer downstream emissions service. This part cross-references Monroe Shocks & Struts (e.g., MN158773, MR507854) for the same application.

The Bosch Engineered Oxygen Sensor line draws on Bosch’s long OE history in oxygen sensing technology, including narrowband designs that improve closed-loop response and measurement accuracy compared with earlier sensor generations. Bosch 15360 follows that approach with a heated design that helps the ECU reach operating feedback sooner after startup.

What It Helps Address

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

Installation Notes

Verify downstream placement before ordering and match the connector, thread size, and harness length to the original sensor. The threaded design installs into the exhaust stream, and the included harness supports direct replacement routing on the vehicle. Use proper oxygen sensor service tools and confirm the connector locks fully after installation.

Quality Assurance

Bosch supplies oxygen sensors with OE-level engineering and materials developed for thermal and vibration resistance. Part Number 15360 is part of the Bosch Engineered Oxygen Sensor line and is built to deliver consistent signal performance for Mitsubishi Lancer downstream service.
