Walker 350-34245 Oxygen Sensor - Downstream Front or Downstream Rear

Walker 350-34245 Oxygen Sensor for Mitsubishi

Walker Products 350-34245 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Mitsubishi applications. It is built for the correct mounting position and ECU feedback, helping restore accurate exhaust monitoring on vehicles such as the Mitsubishi Eclipse, Endeavor, and Galant.

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors for direct-fit service, and this part number is matched to the application, connector style, and threaded mounting requirements listed below.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for direct application matching
• 4-wire configuration with 20-gauge wiring
• Threaded mounting type with 18.0 mm thread diameter
• Radiused polygon male connector for vehicle-specific connection
• Wiring harness length: 26.1
• Overall length: 29.65
• Fits downstream front and downstream rear positions on listed Mitsubishi models

Detailed Description

The Walker 350-34245 oxygen sensor is designed for Mitsubishi Eclipse, Endeavor, and Galant models that require a downstream front or downstream rear sensor in the exact position specified by the vehicle application. As an emissions control sensor, it provides the ECU with the exhaust feedback needed for proper fuel control and diagnostic monitoring. This part number is a practical choice when replacing a failed sensor that has triggered a malfunction indicator light, stored fault codes, or caused drivability and emissions concerns.

Fits 2006-2010 Mitsubishi Eclipse, downstream front; fits 2012 Mitsubishi Eclipse, downstream front; fits 2011 Mitsubishi Eclipse, downstream rear; fits 2004-2008 Mitsubishi Endeavor, downstream front; fits 2009 Mitsubishi Endeavor, downstream front; fits 2010-2011 Mitsubishi Endeavor, downstream front; fits 2004-2009 Mitsubishi Galant, downstream front. Walker Products 350-34245 is built for these specific Mitsubishi oxygen sensor applications.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes stored in the ECU for the affected sensor circuit
• Poor engine operation caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Higher exhaust emissions from a worn or failed sensor

Installation Notes and Tips

Verify the sensor position before installation, since the listed Mitsubishi applications use downstream front and downstream rear locations. Inspect the sensor wiring harness and connector for damage before replacement, and confirm the threaded mounting point is clean and free of corrosion. Use the vehicle’s service information to confirm the correct application for your Mitsubishi Eclipse, Endeavor, or Galant before installing Walker Products 350-34245.

Quality Assurance

Walker Products manufactures engine management sensors as OE-replacement parts for global vehicle applications and operates as an Automotive ISO9001/TS 16949 certified company. Since 1946, the brand has focused on oxygen and air-fuel sensor coverage for service replacement needs.
