Walker 350-34114 Oxygen Sensor

Walker 350-34114 Oxygen Sensor Overview

Walker Products 350-34114 is a heated oxygen sensor built as a specific-fit OE-style replacement for select applications. It is engineered to provide the ECU with the exhaust feedback needed for fuel control and emissions monitoring on vehicles such as the Chevrolet Cruze, Chevrolet Sonic, Chevrolet Trax, and Porsche Macan.

Walker Products Aftermarket focuses on application-specific engine management sensors, and this part number is matched to the correct mounting position, connector style, and wiring configuration for the listed vehicles.

Key Features

• Heated oxygen sensor for exhaust feedback and emissions system monitoring
• Specific fit design for the listed vehicle applications
• 4-wire configuration with 22-gauge wiring
• Female connector with radiused polygon shape
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 20.2
• Overall length: 23.74

Detailed Description

The Walker 350-34114 oxygen sensor is designed for direct replacement in select upstream and downstream positions, depending on the vehicle application. It is used by the engine control unit to monitor exhaust oxygen content and support proper air-fuel management, which is especially important on modern vehicles that store fault codes when sensor performance drops. This part number is listed for 2010-2015 Chevrolet Cruze upstream, 2012-2018 Chevrolet Sonic upstream, 2014-2017 Chevrolet Trax upstream, 2016 Chevrolet Cruze Limited upstream, 2015-2018 Porsche Macan downstream right, and additional Porsche and Saab applications in the fitment data.

Walker Products Aftermarket has developed this sensor as an OE replacement for specific fitment positions, helping maintain the correct diagnostic feedback expected by the ECU. The Walker 350-34114 is a practical choice when replacing a failed upstream oxygen sensor on a Chevrolet Cruze or Chevrolet Sonic, or when servicing a downstream sensor on a Porsche Macan.

What This Sensor 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 control
• Higher exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the exact position before ordering: this part is listed for upstream, downstream, downstream left, and downstream right applications depending on the vehicle. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since physical damage can shorten sensor life. Verify thread size, connector shape, and harness length against the original sensor to ensure proper routing and fit.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates as an Automotive ISO9001/TS 16949 certified company. The 350-34114 is built to match the specified application and provide the diagnostic feedback required by the vehicle ECU.
