Delphi ES10933 Oxygen Sensor - Front, Front Left or Front Right

Delphi ES10933 Oxygen Sensor Overview

Delphi ES10933 is a front oxygen sensor for a wide range of Toyota and Lexus applications that use a 370 mm overall length air-fuel ratio sensor. Built from Delphi’s OE heritage and decades of supplier experience, it is specified for precise front-bank monitoring on vehicles such as the Toyota Tundra, Lexus GX460, and Lexus LS460.

Use this Delphi oxygen sensor when you need a direct-fit replacement for front, front left, or front right positions listed in the application data. The ES10933 features a 4-wire design, square connector shape, and 18 x 1.5 mm thread size for the specified fitments.

• Package contents include the oxygen sensor and instruction sheet
• Fits front, front left, and front right positions depending on vehicle application

Detailed Description

The Delphi ES10933 is an emission control sensor engineered for front-position air-fuel ratio monitoring on many Toyota and Lexus models from 2001 through 2014. It is listed for applications including the Toyota Tundra, Toyota 4Runner, Toyota Tacoma, Toyota Sequoia, Lexus GX460, Lexus GX470, Lexus LS460, Lexus IS250, Lexus IS350, and Lexus LS600h. Delphi’s OE background is reflected in the sensor’s application-specific design and fitment-focused construction.

This part cross-references Bosch 15974 and DENSO Auto Parts 234-9026 for the same application.

What This Sensor Helps Address

• Check engine light related to front oxygen sensor performance
• Incorrect air-fuel ratio readings at the front exhaust position
• Rough idle or drivability issues tied to sensor signal problems
• Emission test failures caused by a faulty upstream sensor
• Replacement needs after sensor aging, contamination, or wiring wear

Installation Notes and Tips

Confirm the exact position before ordering, since ES10933 is listed for front, front left, and front right locations depending on the vehicle. Verify the 370 mm overall length, 4-wire connector, square plug shape, and 18 x 1.5 mm thread size against the original sensor before installation. For best results, compare the application notes in the fitment data, especially model-year breakpoints such as 02/2008 and 05/2005 changes.

Fits 2005-2012 Toyota Sequoia, front; fits 2005-2012 Toyota Tundra, front and front left/right on select years; fits 2007-2013 Lexus LS460, front left/right on select years.

Quality Assurance

Delphi builds this replacement sensor using OE experience gained from supplying major automakers, with OE heritage and application knowledge carried into the aftermarket part. That background supports accurate fitment and consistent sensor design for the listed Toyota and Lexus applications.
