Walker 350-341000 Oxygen Sensor

OE Replacement Oxygen Sensor for Jeep and Ram

Walker OE Replacement oxygen sensor 350-341000 is a specific-fit, heated narrow-band sensor engineered for direct replacement in select Jeep, Ram, Chrysler, and Dodge applications. It is built to deliver the ECU feedback needed for accurate fuel control and emissions monitoring.

Key Features

• Heated narrow-band oxygen sensor for precise exhaust feedback
• Specific-fit design for the listed upstream and downstream positions
• 4-wire configuration with oblong female connector and male spade terminals
• M18 x 1.5 thread size with 22 mm wrench size
• OE Replacement line from Walker Products for application-specific fitment

Detailed Description

The Walker Products OE Replacement line focuses on application-matched engine management components, and part number 350-341000 follows that approach with vehicle-specific fitment and sensor output calibrated for the intended position. This oxygen sensor is used in select Jeep Wrangler, Grand Cherokee, Grand Cherokee L, Wagoneer, Cherokee, and Ram 1500/ProMaster applications, along with Chrysler 300 and Dodge Challenger/Charger coverage. It is a practical choice when replacing a failed upstream or downstream sensor on vehicles that rely on narrow-band feedback for air-fuel control and emissions diagnostics.

This part cross-references Walker Products 350-341000 for the same application.

What This Sensor Helps Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Poor fuel economy caused by inaccurate exhaust feedback
• Rough running or drivability issues tied to air-fuel mixture correction
• Elevated exhaust emissions from a degraded sensor signal
• Fault codes stored in the ECU for the affected sensor circuit or related systems

Installation Notes and Tips

Verify the exact position before ordering, since this sensor is listed for multiple locations including upstream left, upstream right, upstream rear, downstream left, downstream right, and downstream. Inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals before installation. Confirm thread size, connector shape, and terminal style match the original unit, and clear diagnostic trouble codes after replacement if required by the vehicle.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and manufactures this OE Replacement sensor to match the specified application and diagnostic requirements. The company operates under ISO 9001/TS 16949 quality systems for production consistency and application control.
