Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE-style replacements for worldwide vehicle coverage. This part number is built for the specified application and position so the ECU receives the correct diagnostic signal. If the original sensor has failed, the vehicle may run rich or lean, consume more fuel, trigger a malfunction indicator light, or increase exhaust emissions. The Walker 350-34285 is a practical replacement for service work on vehicles such as the Dodge Ram 1500, Jeep Grand Cherokee, and Chrysler Aspen when the listed sensor location matches the vehicle.

This part cross-references OE-style replacement needs for the same application; verify the exact position before ordering.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy from incorrect air-fuel feedback
• Rough running caused by inaccurate exhaust oxygen readings
• Elevated emissions from a failing heated oxygen sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the vehicle year, make, model, and sensor position before installation. This sensor is listed for upstream right, upstream left, downstream right, downstream left, and downstream positions depending on application. Inspect the sensor wiring harness and connector for damage before replacement, since damaged wiring can shorten sensor life and affect operation. Match the threaded mounting and connector style to the original part for proper installation on the Chrysler Aspen, Dodge Dakota, Dodge Durango, Dodge Ram 1500, Jeep Commander, Jeep Grand Cherokee, Mitsubishi Raider, and related listed applications.
