Delphi ES10242 Oxygen Sensor

Delphi ES10242 Oxygen Sensor for OE-Style Emissions Control

The Delphi ES10242 is a heated upstream oxygen sensor built for precise air-fuel feedback in older import applications. It uses OE-based engineering from a supplier with decades of original-equipment experience, helping maintain accurate sensor response in Audi, Volkswagen, Saab, Jaguar, and Hyundai applications.

• Heated oxygen sensor for upstream placement
• 3-wire design with square and round connector shapes
• 18 x 1.5 mm thread size
• Overall length: 1215 mm
• Includes oxygen sensor and instruction sheet
• Delphi part number ES10242

Detailed Product Information

Delphi ES10242 is an upstream heated oxygen sensor engineered for vehicles that rely on a 1215 mm sensor length and OE-style connector configuration. It is listed for a wide range of Audi, Volkswagen, Saab, Jaguar, and Hyundai models, including applications such as the Audi 80, Audi 100, Volkswagen Jetta, Volkswagen Golf, Saab 900, and Jaguar XJ6. The sensor’s heated design supports faster operating temperature, while the 3-wire layout and 18 x 1.5 mm thread size match the specified applications. Delphi ES10242 is a direct-fit emissions control sensor for vehicles requiring this exact length and connector style.

This part cross-references Bosch 13019 and DENSO Auto Parts 234-3019 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect fuel mixture readings from a worn upstream sensor
• Rough idle or drivability issues tied to exhaust feedback
• Failed emissions testing caused by inaccurate sensor output
• Slow sensor response during warm-up on heated applications
