Delphi ES10941 Oxygen Sensor - Front

Delphi ES10941 Oxygen Sensor for Front Applications

The Delphi ES10941 oxygen sensor is built for front-position air-fuel ratio monitoring on select Honda and Acura applications. It combines OE-based engineering with the correct connector, thread size, and lead length for a direct replacement-style repair.

Key Features

• Front oxygen sensor for emissions and fuel-control feedback
• 4-wire design with square connector shape
• 18 x 1.5 mm thread size for proper exhaust bung fitment
• 450.0 overall length for routing and connector placement
• Package contents include the oxygen sensor and instruction sheet
• Delphi OE heritage backed by 100 years of supplier experience

Detailed Description

Delphi ES10941 is an emission control sensor engineered for front sensor locations where accurate exhaust-gas feedback is required. It is listed for 2003-2011 Honda Element, 2006-2009 Honda S2000, 2005-2006 Acura RSX, and 2005-2006 Honda CR-V, including front air-fuel ratio sensor applications on the Element, S2000, and CR-V. If you are searching for a Delphi ES10941 oxygen sensor for Honda Element front or a Delphi ES10941 replacement for Acura RSX front, this part matches the documented fitment and connector specifications.

This sensor cross-references Bosch 15052 for the same application.

What It Helps Address

• Check engine light related to front oxygen sensor performance
• Incorrect air-fuel ratio feedback to the engine control module
• Rough idle or drivability issues tied to exhaust sensor signal errors
• Failed emissions inspection caused by sensor-related fault codes
• Delayed or inaccurate fuel-trim response from the front sensor circuit

Installation Notes and Tips

Verify the connector shape, 4-wire layout, thread size, and overall lead length before installation. Confirm the sensor is being replaced in the front position and compare the original routing path to avoid strain on the harness. Use the included instruction sheet during installation and inspect the exhaust bung threads for damage before threading in the new sensor.

Quality Assurance

Delphi builds this part using OE heritage and supplier knowledge developed through decades of original-equipment experience. That background is reflected in the sensor design, connector configuration, and application-specific fitment support for Honda and Acura front sensor locations.
