Detailed Description

Denso 234-4319 is a direct replacement oxygen sensor for the 2007-2013 Mitsubishi Outlander, upstream right. It is a heated, threaded sensor with a specific-fit design, 4-wire layout, and male connector to match the original vehicle configuration. The OE Style construction is intended to deliver the correct fit and signal performance for emissions system service on the Mitsubishi Outlander.

This part cross-references Bosch 15795 and NTK 23524 for the same application. If you are replacing a worn upstream oxygen sensor on a Mitsubishi Outlander, part number 234-4319 provides a catalog-matched option for the correct position and connector style.

Common Issues This Part Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings from a failing upstream sensor
• Reduced fuel economy caused by inaccurate exhaust feedback
• Slow sensor response during closed-loop engine operation
• Emissions test failure tied to a degraded oxygen sensor

Installation Notes and Tips

Verify the upstream right location before installation on the 2007-2013 Mitsubishi Outlander. Confirm connector style, wire count, thread diameter, and harness routing against the original sensor before removal. Use proper oxygen sensor service tools and follow the vehicle service procedure for torque and connector handling.

Quality Assurance

Denso manufactures and tests this OE Style oxygen sensor to original equipment standards for direct replacement use. The design includes a protective aluminum oxide trap layer to help shield the sensing element from contamination and support long-term performance. Part number 234-4319 is built for the specified application and fitment.
