Detailed Description

The Delphi ES10664 is an emission control oxygen sensor engineered for the Toyota Celica and Toyota Camry applications listed below. Delphi builds aftermarket parts using OE heritage and technical knowledge developed through long-term supplier relationships with major automakers, and that background is reflected in the sensor’s fitment-focused design and construction. This part cross-references Bosch 12109 for the same application.

Fits 1996-1997 Toyota Celica, front. Fits 1994-1996 Toyota Camry, rear. Fits 1992-1993 Toyota Camry, rear with California Emission System. The Delphi ES10664 is a practical replacement choice when the original sensor has aged, wiring has deteriorated, or exhaust feedback performance has become inconsistent.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect exhaust oxygen signal to the engine control system
• Rough idle or drivability issues tied to sensor aging
• Failed emissions inspection caused by a worn sensor
• Corrosion or connector wear at the original sensor location

Installation Notes and Tips

Confirm the sensor position before ordering, since this part is listed for front and rear applications depending on the vehicle. Verify thread size, connector shape, and wire count against the original sensor before installation. For the Toyota Camry, note the California Emission System requirement on 1992-1993 rear applications. Use the vehicle application details to match the correct location for your Toyota Celica or Toyota Camry.

Quality Assurance

Delphi draws on 100 years of OE experience and supplier knowledge from top automakers to support consistent aftermarket replacement quality. The ES10664 is built as an OE-style emission control sensor for the specified applications.
