Walker 250-24233 Oxygen Sensor

OE Oxygen Sensor for Mitsubishi and Chrysler Applications

Walker Products OE 250-24233 is a heated oxygen sensor built as a direct replacement for specific upstream positions on select Mitsubishi, Chrysler, and Dodge vehicles. It is engineered for the exact fitment position and ECU feedback required by the application, helping maintain proper air-fuel control and emissions system operation.

Walker Products OE focuses on engine management sensors built to original equipment replacement standards. This line is developed for precise application matching, including connector style, thread size, harness length, and mounting position, making it a practical choice for Mitsubishi Eclipse, Galant, Lancer, Outlander, and related models.

Detailed Description

This Walker Products OE oxygen sensor is designed for upstream exhaust locations where the ECU relies on accurate exhaust-gas feedback to manage fuel delivery and emissions performance. The sensor is a direct-fit replacement for select Mitsubishi Eclipse, Galant, Lancer, Mirage, Diamante, Endeavor, and Outlander models, along with certain Chrysler Sebring and Dodge Stratus applications. Fits 2001-2012 Mitsubishi Eclipse, Upstream Front and Upstream Rear; Fits 2001-2009 Mitsubishi Galant, Upstream Front and Upstream Rear; Fits 2002-2007 Mitsubishi Lancer, Upstream; Fits 2007-2013 Mitsubishi Outlander, Upstream Left.

Part number 250-24233 is built for specific application matching, so the connector, harness length, and threaded mounting style align with the intended vehicle position. This part cross-references no additional part numbers listed for the same application.

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 control
• Elevated exhaust emissions from a failing upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the exact vehicle position before ordering, since this sensor is listed for upstream front, upstream rear, and upstream left applications depending on model and year. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. Verify thread diameter, connector shape, and harness routing against the original sensor to ensure proper fitment on the exhaust system.
