Key Features

• Heated oxygen sensor for downstream bank 1 sensor 2 applications
• Specific fit design for select 1995-1999 Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse models
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for application-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Overall length: 25.91 in.; wiring harness length: 22.36 in.

Detailed Description

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered to match original equipment requirements for the specified vehicle and sensor position. Part number 350-34124 is built for downstream bank 1 sensor 2 service on select 1995-1999 Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse applications, helping the ECU receive the correct feedback from the exhaust stream. This part number is a direct-fit replacement for the listed models and positions, making it a practical choice when replacing a worn or failed oxygen sensor on these vehicles.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Higher exhaust emissions from a failing downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the connector shape, wire count, thread diameter, and sensor position before installation. For best results, inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. Confirm the vehicle application as downstream bank 1 sensor 2 on the listed Chrysler Sebring, Dodge Avenger, or Mitsubishi Eclipse models before replacement.

Quality Assurance

Walker Products states that its engine management sensors are developed as OE replacement parts and manufactured under ISO 9001/TS 16949 quality systems. Since 1946, the brand has supplied engine management and fuel system components for automotive applications.
