Bosch 13383 Oxygen Sensor - Downstream, Upstream or Upstream Front

Bosch Oxygen Sensor for Mitsubishi and Dodge

Bosch 13383 is a specific-fit, narrow-band heated oxygen sensor built for upstream engine management on select Mitsubishi and Dodge applications. It delivers air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate combustion adjustment, and lower emissions.

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for faster sensor response and closed-loop operation
• 4-wire configuration with square female connector
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Wiring harness included with 8.6 in harness length
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions

Product Line Details

The Bosch Engineered Oxygen Sensor line reflects Bosch OE development in switching-type O2 sensor technology. Bosch has refined sensor design from early thimble-style units to planar narrowband construction, focusing on quicker light-off, improved lambda accuracy, and consistent heater control across changing exhaust temperatures.

Detailed Description

Bosch part number 13383 is engineered for upstream oxygen sensor locations on 1993-1998 Mitsubishi Galant, 1993-1996 Mitsubishi Mirage, and 1993-1995 Dodge Colt applications listed in the fitment data. It is a standard replacement sensor with a pin terminal type, female connector and terminal ends, and a threaded mount for direct exhaust installation. Bosch uses advanced ceramic elements and heat-resistant materials to maintain stable signal output under thermal cycling and vibration. This part cross-references Mitsubishi MD182691 and MD198529 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 exhaust feedback
• Slow closed-loop transition after startup
• Unstable idle or drivability issues tied to air-fuel control
• Emissions test failures linked to worn upstream sensor performance

Installation Notes and Tips

Install Bosch 13383 in the upstream position specified for your vehicle and verify connector shape, wire count, and thread size before replacement. Use the fitment notes to confirm California-emissions and OE-specific applications for Mitsubishi Galant, Mitsubishi Mirage, and Dodge Colt models. Inspect the exhaust bung threads and wiring routing before tightening the sensor to the specified location.

Quality Assurance

Bosch supplies oxygen sensors with OE-proven engineering developed over decades of original equipment experience. Bosch 13383 is built to the same functional standards expected from a standard replacement sensor for precise exhaust feedback and dependable operation.
