Delphi ES20360 Oxygen Sensor - Front, Rear or Rear Right

Delphi ES20360 Oxygen Sensor Overview

The Delphi ES20360 is a heated oxygen sensor built for precise exhaust monitoring in select Toyota, Lexus, and Supra applications. It combines OE-based engineering with a 4-wire design, square connector, and 18 x 1.5 mm thread size for direct-fit replacement in the listed front and rear right positions.

Fits 1993-2016 Toyota Tundra, rear right; fits 2005-2012 Toyota Tacoma, rear; and fits 2000-2005 Lexus GS300, front. This Delphi oxygen sensor is also listed for select Lexus SC300 and Toyota Supra front positions with California emissions configurations.

Key Features

• Heated oxygen sensor for faster operating temperature and stable exhaust feedback
• 4-wire configuration for the listed vehicle applications
• Square connector shape for OE-style electrical connection
• 18 x 1.5 mm thread size for proper exhaust bung fitment
• Overall length: 510.0
• Package includes the oxygen sensor and instruction sheet
• Fits front, rear, and rear right positions depending on application

Detailed Description

Delphi ES20360 is engineered from more than a century of OE experience and supplier knowledge used by major automakers. That OE heritage is reflected in the sensor’s construction, connector style, and application coverage across Toyota Tundra, Toyota Tacoma, Toyota Sequoia, Lexus GS300, Lexus SC300, and Toyota Supra listings. For buyers searching for a Delphi ES20360 oxygen sensor, this part provides a direct replacement option for the specified emissions-control positions.

This part cross-references Bosch 15247 for the same application. It is also listed among interchange references including DENSO Auto Parts 234-4624 and 234-4626.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback from a worn upstream or downstream sensor
• Reduced emissions monitoring accuracy
• Rough idle or drivability issues tied to faulty exhaust oxygen readings
• Failed emissions inspection caused by sensor degradation

Installation Notes and Tips

Verify the exact position before ordering, since this sensor is listed for front, rear, and rear right locations depending on the vehicle. Confirm thread size, connector shape, and wire count against the original sensor before installation. For fitment-specific applications, use the vehicle’s application tab and match the notes shown for California emissions or date-specific coverage such as To 08/2015 and To 08/2013.

Quality Assurance

Delphi builds aftermarket parts using OE-based engineering and supplier experience developed through work with leading automakers. That background supports consistent fitment and sensor construction for the listed Toyota and Lexus applications.
