Bosch 13460 Oxygen Sensor - Downstream or Upstream

Bosch Validated Oxygen Sensor 13460

Bosch Validated Oxygen Sensor 13460 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 on select Mitsubishi and Dodge applications, including Mitsubishi Eclipse, Mirage, Expo, and Galant, plus Dodge Colt and Ram 50 fitments.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster closed-loop operation
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• 4-wire configuration with square female connector and pin terminals
• Metal housing with high-temperature-resistant construction
• Wiring harness included for the listed applications
• Bosch Validated Oxygen Sensor line backed by Bosch OE development experience

Product Details

Bosch part number 13460 uses a switching-type narrow-band sensor element to report exhaust oxygen content to the engine control unit. Bosch developed this sensor family from its original thimble design and later planar narrowband technology, focusing on quicker light-off, accurate lambda feedback, and reliable closed-loop response. For drivers servicing older Mitsubishi and Dodge emissions systems, Bosch 13460 provides the OE-style signal behavior needed for consistent fuel control.

This part cross-references Monroe Shocks & Struts (e.g., MD142206, MD183145) for the same application.

Installation Notes

Verify the connector shape, wire count, thread size, and upstream or downstream position before installation. This Bosch Validated Oxygen Sensor 13460 is a specific-fit threaded sensor, so matching the vehicle’s emission configuration is important, especially on California Emission System applications. Inspect the harness routing and connector condition during replacement, and confirm the exhaust bung threads are clean before tightening the sensor.

Quality Assurance

Bosch draws on more than five decades of OE oxygen sensor development, including original sensor designs and later planar narrowband technology used to improve response and accuracy. Bosch 13460 is part of the Bosch Validated Oxygen Sensor line and is built to OE-proven standards for durable operation in high heat and vibration environments.
