Walker 250-24251 Oxygen Sensor

Walker Products OE Oxygen Sensor for Chrysler, Dodge, and Mitsubishi

Walker Products OE 250-24251 is a heated oxygen sensor built for specific vehicle applications and exact mounting positions. It is engineered as an OE-style replacement for vehicles that rely on accurate exhaust feedback to help the ECU manage fuel delivery and emissions.

For Chrysler Aspen, Dodge Dakota, Dodge Durango, Mitsubishi Raider, and Chrysler Pacifica applications, this sensor is positioned to match the original location and connector style. If your vehicle has a fault code, poor fuel economy, or an illuminated malfunction indicator light, the oxygen sensor circuit is one of the first areas to inspect.

Product Details

Walker Products OE focuses on engine management and oxygen/air-fuel sensors developed as original-equipment replacement parts. Part number 250-24251 is built for specific placement on the vehicle, including upstream and downstream positions where listed, so the sensor output matches the diagnostic needs of the engine control system. This part number 250-24251 is a direct-fit style solution for drivers servicing emissions-related faults on Chrysler Aspen, Dodge Dakota, Dodge Durango, Mitsubishi Raider, and Chrysler Pacifica models.

Walker Products has supplied engine management components since 1946 and manufactures to automotive ISO 9001/TS 16949 standards. The OE product line is aimed at application-specific replacement, with attention to connector design, harness length, and sensor configuration for the listed vehicles.

What It Helps Address

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

Installation Notes

• Verify the exact position before ordering: upstream right, downstream right, downstream left, or upstream, depending on the vehicle.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Confirm thread size and connector style match the original sensor on the vehicle.
• Use the vehicle’s service information for torque and routing specifications.

Quality Assurance

Walker Products OE 250-24251 is manufactured as an OE replacement sensor for the listed applications and produced under ISO 9001/TS 16949 quality systems. Walker Products OE is the product line for application-specific engine management sensors and fuel system components.
