Denso OE Style Oxygen Sensor 234-2067

Denso 234-2067 is an OE Style oxygen sensor built for direct replacement on select Mitsubishi Mighty Max and Dodge Ram 50 applications. It uses a specific-fit, threaded design with a 17.80-inch wiring harness, 2-wire layout, female connector, and non-heated sensor construction for the correct factory-style match.

Key Features

• OE Style replacement oxygen sensor for precise fitment
• Specific fit design for select upstream applications
• Non-heated sensor with 2-wire configuration
• 17.80-inch wiring harness length
• Female connector and threaded mounting type
• 0.708-inch thread diameter for proper installation match

Detailed Description

Denso 234-2067 is engineered as a direct-fit oxygen sensor for upstream locations on select 1990-1995 Mitsubishi Mighty Max and Dodge Ram 50 models. It is built to OE standards for accurate replacement fitment and consistent signal performance, making it a practical choice when replacing a worn sensor on a Mitsubishi Mighty Max or Dodge Ram 50. This part cross-references Bosch 12041 and NTK 23501 for the same application.

The Denso OE Style line focuses on exact replacement geometry and factory-style compatibility. Denso also uses an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine operation and fuel control over time. The part number 234-2067 is a direct replacement option for drivers servicing upstream emissions components on these vehicles.

Vehicle Fitment

• Fits 1993-1995 Mitsubishi Mighty Max, upstream, excluding California; OE Style
• Fits 1993 Dodge Ram 50, upstream, excluding California; OE Style
• Fits 1991-1992 Dodge Ram 50, upstream, OE Style

What It Helps 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
• Rough idle or drivability issues tied to sensor degradation
• Emissions test failures linked to a worn oxygen sensor

Installation Notes and Tips

Confirm the connector style, thread diameter, and upstream location before installation. This sensor uses a threaded mounting type and a female connector, so the vehicle harness and bung must match the OE-style configuration. For best results, inspect the exhaust threads and wiring routing during replacement on Mitsubishi Mighty Max and Dodge Ram 50 applications.

Quality Assurance

Denso manufactures and tests this oxygen sensor to strict OE standards for fit and function. The OE Style design is intended to deliver the correct replacement geometry and dependable performance for the listed applications.
