Detailed Description

Delphi ES10224 is an upstream oxygen sensor engineered for older Toyota emissions-control systems that use a non-heated, single-wire sensor layout. The 18 x 1.5 mm thread and 350 mm lead length help match factory-style mounting and routing on vehicles such as the Toyota Camry, Corolla, Celica, Cressida, Tercel, Pickup, 4Runner, Supra, and Van. Delphi draws on decades of OE experience, and that heritage is reflected in the sensor’s fit-focused construction and signal-monitoring role.

This part cross-references Bosch 12051 and Four Seasons 24611 for the same application. The Delphi ES10224 part number is also commonly searched by buyers replacing an upstream Toyota oxygen sensor on California and non-California emission configurations where listed.

Installation Notes and Tips

Confirm the sensor position, connector style, thread size, and lead length before installation. This ES10224 oxygen sensor is specified for upstream use, so verify the vehicle’s emission configuration and mounting style against the fitment notes before replacing the original part.

For best results, inspect the harness routing and exhaust bung condition during service. Use the included instruction sheet as a reference for installation steps and connector handling.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and knowledge developed through long-term supplier experience with major automakers. The ES10224 reflects that OE-focused approach for emissions-control service on select Toyota models.
