Walker 250-21024 Oxygen Sensor - Upstream

Walker OE Oxygen Sensor for Volkswagen Vanagon

Walker Products OE 250-21024 is a specific-fit oxygen sensor engineered as an OE-style replacement for select applications. It is built for upstream placement and uses a threaded mount with a female radiused polygon connector for direct replacement on supported vehicles, including Volkswagen Vanagon models from 1980-1983.

Key Features

• Specific-fit oxygen sensor for targeted vehicle applications
• Upstream sensor position for ECU feedback at the front of the exhaust system
• Non-heated design
• 18.0 mm thread diameter with threaded mounting type
• 16.46 in. wiring harness length and 20-gauge wire
• Female radiused polygon connector
• Overall length: 20.0 in.

Product Details

Walker Products OE 250-21024 is part of the Walker Products OE line, which focuses on replacement sensors built around application-specific fitment and diagnostic feedback requirements. This oxygen sensor is intended for vehicles that use an upstream sensor to help the ECU monitor exhaust oxygen content and adjust engine management accordingly. For Volkswagen Vanagon owners, the correct upstream oxygen sensor is important for maintaining proper fuel control and emissions system operation.

Fits 1980-1983 Volkswagen Vanagon, upstream. Fits 1980-1983 Volkswagen Vanagon, upstream, Bank 1 Sensor 1 needs an upstream oxygen sensor. Fits 1980-1983 Volkswagen Vanagon, upstream, front oxygen sensor compatible with various vehicle models.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel control
• Higher exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor-related issues

Installation Notes and Tips

Confirm the sensor position before ordering, since this part is specified for upstream use. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. Verify thread diameter, connector style, and harness length against the original part to ensure proper routing and fitment on the Volkswagen Vanagon.

Quality Assurance

Walker Products states that its engine management and oxygen/air-fuel sensors are developed as OE replacement parts and manufactured under ISO 9001/TS 16949 quality systems. The Walker Products OE 250-21024 is built for application-specific fitment and ECU feedback requirements.
