Delphi ES11075 Oxygen Sensor - Front

Front Heated Oxygen Sensor for Ford Applications

Delphi ES11075 is a front heated oxygen sensor built for precise exhaust monitoring in select Ford vehicles. It uses a 4-wire design with a square connector and 18 x 1.5 mm thread size for direct replacement service on the listed applications.

Key Features

• Heated oxygen sensor for faster operating response
• 4-wire configuration
• Square connector shape
• 18 x 1.5 mm thread size
• Front position application
• Includes oxygen sensor and instruction sheet

Detailed Description

Delphi ES11075 is an emission control sensor engineered for front sensor locations on 2008-2011 Ford Focus and 2010-2013 Ford Transit Connect. Delphi draws on OE heritage and decades of supplier experience, bringing factory-level design knowledge into this aftermarket oxygen sensor. The ES11075 is a direct-fit replacement for vehicles that require a heated, 4-wire front O2 sensor with a square connector and 18 x 1.5 mm thread.

This part cross-references DENSO Auto Parts 234-4107 and NTK 22015 for the same application. Search terms such as Ford Focus front oxygen sensor, Ford Transit Connect front O2 sensor, and Delphi ES11075 oxygen sensor help identify the correct emission control replacement for these vehicles.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings
• Reduced fuel economy caused by faulty exhaust feedback
• Rough idle or drivability issues tied to sensor signal errors
• Emission test failures from a worn front sensor

Installation Notes and Tips

Verify connector shape, wire count, thread size, and sensor position before installation. This front sensor is listed for 2008-2011 Ford Focus, front, and 2010-2013 Ford Transit Connect, front. Confirm the exhaust bung matches 18 x 1.5 mm threads and route the harness away from heat sources during installation. Use the included instruction sheet as a reference for vehicle-specific service steps.

Quality Assurance

Delphi builds this oxygen sensor with OE experience and supplier knowledge developed over many years of factory-level automotive work. That background supports consistent fitment and sensor construction for the listed Ford applications.
