Delphi ES20414 Oxygen Sensor - Center, Front or Rear

OE Oxygen Sensor for Mitsubishi Applications

Delphi ES20414 is a heated oxygen sensor built for direct-fit replacement on select Mitsubishi vehicles. It combines OE heritage with application-specific fitment for the Mitsubishi Lancer, Outlander, and Outlander Sport across front, center, and rear positions.

Key Features

• Heated oxygen sensor for faster sensor warm-up and stable exhaust monitoring
• 4-wire design with square connector shape
• 18 x 1.5 mm thread size for the listed applications
• Overall length: 950.0
• Includes oxygen sensor and instruction sheet
• Fits center, front, and rear positions depending on vehicle configuration

Detailed Description

Delphi ES20414 is engineered for Mitsubishi Lancer, Mitsubishi Outlander, and Mitsubishi Outlander Sport fitments that require a heated oxygen sensor with a square connector and 4-wire layout. Delphi draws on more than 100 years of OE experience, and that background is reflected in the sensor design and manufacturing approach used for this aftermarket replacement. This part cross-references Bosch 18074 for the same application.

Use Delphi ES20414 when replacing a worn upstream or downstream oxygen sensor on the listed Mitsubishi models. It is a direct replacement for vehicles with the specified position and emissions configuration, including applications with and without California Emission System coverage where noted.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle or inconsistent air-fuel feedback
• Reduced fuel economy caused by inaccurate exhaust readings
• Emissions test failures tied to sensor response issues
• Slow sensor warm-up on heated oxygen sensor applications

Installation Notes and Tips

• Verify the exact position before ordering: front, center, or rear.
• Match the vehicle’s emissions configuration, including California Emission System notes where listed.
• Confirm the connector shape, wire count, and thread size before installation.
• Inspect the exhaust bung and wiring routing during replacement to avoid damage to the new sensor.
• For fitment-specific use, refer to the application details for your Mitsubishi Lancer, Outlander, or Outlander Sport.

Quality Assurance

Delphi builds this oxygen sensor using OE-focused engineering and manufacturing knowledge developed through long-term supplier experience with major automakers. That OE background supports consistent fitment and sensor performance across the listed Mitsubishi applications.
