Delphi ES10261 Oxygen Sensor for Volkswagen Vanagon

Delphi ES10261 is a heated upstream oxygen sensor built for precise exhaust feedback and OE-style fitment. It is compatible with 1986-1991 Volkswagen Vanagon models with 680 mm overall length, making it a direct-match option for service on the Vanagon exhaust system.

Key Features

• Heated oxygen sensor for faster operating temperature
• 3-wire design
• Flat and square connector shape
• 18 x 1.5 mm thread size
• 680.0 overall length
• Upstream position
• Includes oxygen sensor and instruction sheet

Detailed Description

Delphi ES10261 is an upstream heated oxygen sensor engineered with Delphi’s OE heritage and decades of supplier experience behind it. For 1986-1991 Volkswagen Vanagon applications, this sensor helps provide the exhaust feedback the engine management system relies on for air-fuel control. The 3-wire heated design supports quicker sensor warm-up, while the flat and square connector and 18 x 1.5 mm thread size help match the original-style installation requirements. If you are replacing a worn Volkswagen Vanagon oxygen sensor, ES10261 offers a fitment-specific solution for the listed vehicles.

This part cross-references DENSO Auto Parts 234-3028 and Walker Products 250-23124 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough idle caused by inaccurate exhaust feedback
• Reduced fuel control from a slow or aging upstream sensor
• Emissions test failures tied to sensor response issues
• Driveability problems on 1986-1991 Volkswagen Vanagon models

Installation Notes and Tips

Verify the upstream location, connector shape, thread size, and 680 mm overall length before installation. Compare the old sensor’s connector and harness routing to confirm the replacement matches the vehicle’s original configuration. Follow the included instruction sheet and use proper exhaust sensor service practices to avoid thread damage during removal and installation.

Quality Assurance

Delphi builds aftermarket parts using OE experience and knowledge developed through long-term supply relationships with major automakers. ES10261 reflects that OE-focused background for Volkswagen Vanagon oxygen sensor service.
