Delphi ES10930 Oxygen Sensor - Front

Front Oxygen Sensor for Toyota and Subaru

Delphi ES10930 is a front oxygen sensor built for specific Toyota Camry, Toyota Solara, and Subaru Outback applications. It uses a 4-wire design, square connector shape, and 18 x 1.5 mm thread size for direct-fit replacement on listed vehicles.

Key Features

• Front-position oxygen sensor for emission control service
• 4-wire configuration with square connector shape
• 18 x 1.5 mm thread size
• Overall length: 520.0
• Package contents: oxygen sensor and instruction sheet
• Delphi ES10930 part number for OE-style replacement lookup

OE Heritage and Sensor Design

Delphi builds this oxygen sensor using OE experience developed through supplier relationships with major automakers. That background is reflected in the sensor’s fit, connector style, and thread specification, making it a practical replacement for front air-fuel ratio sensor applications on Toyota Camry, Toyota Solara, and Subaru Outback models listed below. The Delphi ES10930 is also a useful cross-reference for shoppers comparing replacement options by part number.

This part cross-references DENSO Auto Parts (e.g., 234-9010, 234-9024) for the same application.

Vehicle Fitment

• Fits 2001-2004 Subaru Outback, front
• Fits 2003 Toyota Camry, front, without California Emission System; Air-Fuel Ratio Sensor
• Fits 2002-2003 Toyota Solara, front, Air-Fuel Ratio Sensor
• Fits 2002 Toyota Camry, front, Air-Fuel Ratio Sensor
• Fits 2000 Toyota Camry, front, Air-Fuel Ratio Sensor
• Fits 1992 Toyota Camry, front, Air-Fuel Ratio Sensor
• Fits 2001 Toyota Camry, front
• Fits 1999-2001 Toyota Solara, front, with California Emission System; Air-Fuel Ratio Sensor
• Fits 1997-2000 Toyota Camry, front, with California Emission System; Air-Fuel Ratio Sensor

Common Issues This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings at the front sensor location
• Emissions test failure caused by a faulty upstream sensor
• Rough idle or drivability concerns tied to sensor signal loss
• Replacement need after sensor contamination or age-related wear

Installation Notes and Tips

Verify the connector shape, wire count, and thread size before installation. This Delphi ES10930 is a front sensor, so confirm the vehicle’s upstream location and emission-system notes, especially on Toyota Camry and Toyota Solara applications with California Emission System or without California Emission System. Compare the original sensor length and connector routing to the replacement part before final installation.

Quality Assurance

Delphi applies more than a century of OE experience to its aftermarket emission-control parts, with engineering knowledge carried over from original equipment development. That OE background supports consistent fitment and sensor construction for the listed applications.
