Walker 350-34111 Oxygen Sensor - Downstream

Walker 350-34111 Oxygen Sensor Overview

Walker Products 350-34111 is a heated oxygen sensor built as a specific-fit OE replacement for select Chrysler and Dodge applications. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring, with fitment focused on the downstream position.

Compatible With 1996-2000 Chrysler Sebring downstream and 1997-1998 Dodge Stratus downstream, this sensor is intended for direct replacement use where the original sensor has failed or is reporting incorrect data. The Walker Products Aftermarket line focuses on application-specific engine management and oxygen sensor coverage for vehicle-specific fitment.

Detailed Product Description

Walker Products 350-34111 is an oxygen sensor for downstream installation on select Chrysler Sebring and Dodge Stratus models. As a heated sensor, it is designed to reach operating temperature quickly and deliver the feedback the engine control unit uses to manage emissions-related operation. The specific-fit design helps match the original sensor location, connector style, and threaded mounting requirements for the listed vehicles.

This part is a practical replacement when diagnosing a check engine light tied to oxygen sensor performance, fuel economy changes, elevated exhaust emissions, or poor engine operation. The Walker Products Aftermarket line is built around application-specific engine management components, and this sensor follows that approach for the 1996-2000 Chrysler Sebring and 1997-1998 Dodge Stratus downstream positions. Part number 350-34111 is also a useful reference when verifying the correct replacement before ordering.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Incorrect air-fuel feedback reported to the ECU
• Reduced fuel economy caused by a failing sensor
• Higher exhaust emissions from inaccurate sensor readings
• Poor engine performance linked to sensor degradation

Installation Notes and Tips

• Confirm the downstream position before installation.
• Verify connector shape, wire count, and thread diameter against the original sensor.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion.
• Check stored ECU fault codes to confirm the affected circuit before replacement.
• Use the vehicle application details for 1996-2000 Chrysler Sebring and 1997-1998 Dodge Stratus to confirm fitment.
