Walker 250-23024 Oxygen Sensor - Upstream

Walker OE Oxygen Sensor for Porsche

Walker Products OE oxygen sensor Part Number 250-23024 is a specific-fit, heated upstream sensor engineered for accurate ECU feedback on select Porsche applications. It is built for 1983-1987 Porsche 928 and 1984-1985 Porsche 911 upstream positions, making it a direct replacement for vehicles that need precise exhaust monitoring.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the correct application and mounting position
• Threaded mounting type with 18.0 mm thread diameter
• 19.21 in. wiring harness length and 20-gauge wire
• Radiused polygon connector design with male and female connector genders listed in the application data
• Walker Products OE line replacement for Porsche 928 and Porsche 911 upstream sensor locations

Product Details

The Walker Products OE line focuses on engine management sensors built as OE-style replacements for application-specific fitment. Part Number 250-23024 is a heated oxygen sensor designed to deliver the diagnostic feedback the ECU expects from the upstream location. For Porsche 928 and Porsche 911 models, the upstream oxygen sensor plays a direct role in air-fuel control, emissions monitoring, and drivability.

Fits 1983-1987 Porsche 928, upstream. Fits 1984-1985 Porsche 911, upstream. This part number, 250-23024, is a practical choice when replacing a worn sensor that has triggered fault codes or caused poor engine performance. This part cross-references Bosch (e.g., 13275) for the same application.

Common Issues This Sensor May Address

• Check engine or malfunction indicator light related to oxygen sensor performance
• Rough running or inconsistent fuel control
• Increased fuel consumption from inaccurate exhaust feedback
• Higher exhaust emissions caused by a degraded upstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the upstream location before installation and verify connector style, thread diameter, and harness routing against the original part. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten sensor life and affect signal quality. The threaded mounting design supports direct replacement on the listed Porsche applications.

Quality Assurance

Walker Products OE sensors are developed as original-equipment replacement parts for specific vehicle applications. The brand’s engine management catalog is built around application-specific fitment and ECU feedback requirements, with manufacturing supported by ISO 9001 and TS 16949 quality systems. Part Number 250-23024 reflects that OE-focused approach for Porsche 928 and Porsche 911 upstream oxygen sensor replacement.
