Product Details

Walker Products Engine Management and Oxygen/Air-Fuel sensors are developed as OE-style replacements for a wide range of vehicles. This sensor is built for the specified application and fitment position so the ECU receives the correct diagnostic signal. On affected Dodge Durango, Dakota, Ram 1500, and Ram 2500 models, a failing oxygen sensor can contribute to rough running, higher fuel use, increased exhaust emissions, and a malfunction indicator light.

Walker Products has supplied engine management and fuel system components since 1946 and operates with Automotive ISO9001/TS 16949 certification. The 350-34655 is part of the Walker Products Aftermarket line focused on application-specific sensor replacement.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy from incorrect air-fuel feedback
• Rough engine operation caused by inaccurate exhaust readings
• Elevated exhaust emissions from a worn sensor
• Fault codes stored in the ECU for sensor-related issues
