Delphi ES20141 Oxygen Sensor - Front or Rear

Delphi ES20141 Oxygen Sensor Overview

The Delphi ES20141 is a heated oxygen sensor built for precise exhaust monitoring in select Honda applications. With OE-based engineering and a 4-wire design, it supports accurate air-fuel feedback for front and rear sensor locations where specified by the vehicle application.

Compatible With 1994-2002 Honda Accord, 1994-1996 Honda Prelude, 1999-2001 Honda Odyssey, and 2000-2001 Honda Insight applications. This part cross-references Bosch 13322 and DENSO Auto Parts 234-4094 for the same application.

Key Features

• Heated oxygen sensor design for faster operating temperature
• 4-wire configuration for signal and heater circuit operation
• Square connector shape for application-specific fitment
• 18 x 1.5 mm thread size
• Overall length: 340.0
• Includes oxygen sensor and instruction sheet
• Fits front and rear positions where listed by vehicle application

Detailed Description

Delphi ES20141 is engineered from more than a century of OE experience and supplier knowledge built into aftermarket replacement parts. As an emission control oxygen sensor, it monitors exhaust oxygen content so the engine control system can maintain the proper fuel mixture. That helps support stable drivability, emissions performance, and efficient engine operation in the Honda Accord, Honda Prelude, Honda Odyssey, and Honda Insight applications listed below.

Fits 1996-2002 Honda Accord, front. Fits 2000-2001 Honda Insight, rear. Fits 1999-2001 Honda Odyssey, rear. Fits 1996 Honda Prelude, front. Fits 1994-1995 Honda Accord, N/A. Fits 1994-1995 Honda Prelude, N/A. Delphi ES20141 is a direct-fit style oxygen sensor for vehicles requiring the specified connector, thread size, and heated 4-wire layout.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn sensor
• Rough idle or hesitation caused by inaccurate exhaust feedback
• Reduced fuel economy from poor mixture control
• Emissions test failures tied to sensor response issues

Installation Notes and Tips

Verify the sensor position in the vehicle application before ordering, since this part is listed for front and rear locations depending on model year. Confirm connector shape, thread size, and wire count against the original sensor before installation. Use the included instruction sheet and follow proper exhaust sensor removal procedures to avoid damage to the threads or wiring.

Quality Assurance

Delphi builds this oxygen sensor using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The ES20141 is made to meet the demands of emission control service in the listed Honda applications.
