Delphi ES10955 Oxygen Sensor - Rear

Delphi ES10955 Oxygen Sensor Overview

The Delphi ES10955 is a non-heated oxygen sensor built for specific Toyota applications that require a 2-wire, square-connector design with an 18 x 1.5 mm thread. It is a direct-fit emission control sensor for select Toyota Camry, Celica, and MR2 models, including California-emissions configurations.

Delphi draws on OE experience and supplier knowledge developed over decades of working with major automakers, bringing that background into this aftermarket oxygen sensor. The ES10955 is a practical choice when you need accurate replacement coverage for Toyota oxygen sensor service.

What It Helps Address

• Check engine light concerns related to oxygen sensor performance
• Incorrect exhaust oxygen readings affecting fuel control
• Emission test failures tied to sensor response issues
• Rough idle or drivability problems caused by aging sensor output
• Replacement needs on Toyota Camry, Celica, and MR2 emission systems

Installation Notes and Tips

Confirm the sensor position, connector style, thread size, and overall length before installation. This ES10955 oxygen sensor is listed for front and rear positions depending on the vehicle, so match the application tab to your exact Toyota Camry, Celica, or MR2 configuration. Verify California-emissions and screw-type requirements where noted in the fitment data.

Use the included instruction sheet during installation and inspect the exhaust bung threads before threading the sensor into place.

Quality Assurance

Delphi builds on more than a century of OE experience and supplier knowledge gained from working with leading automakers. That OE heritage is reflected in the ES10955 oxygen sensor’s application-specific design and emission control focus.
