Walker 250-23153 Oxygen Sensor - Upstream

OE Base Oxygen Sensor for Volkswagen Golf

Walker OE Base Sensor 250-23153 is a specific-fit, heated narrow-band oxygen sensor built for the 1992 Volkswagen Golf upstream B1S1 position. It is engineered as an OE replacement sensor for vehicles that rely on accurate exhaust feedback to the ECU, helping maintain proper air-fuel control and emissions monitoring.

Key Features

• Specific-fit oxygen sensor for the upstream position
• Heated narrow-band design for faster operating temperature
• 3-wire configuration with spade terminals
• Female connector with rectangular shape
• M18 x 1.5 thread size and 22 mm wrench size
• Walker OE Base Sensor line for OE-style replacement applications

Detailed Description

Walker Products 250-23153 is part of the OE Base Sensor line, a product range focused on direct replacement oxygen and air-fuel sensors for defined vehicle applications. For the 1992 Volkswagen Golf, upstream B1S1 fitment means the sensor is positioned before the catalytic converter, where it provides feedback the ECU uses to adjust fuel delivery and monitor emissions performance. This part number 250-23153 is built for the specified application rather than universal use, which helps ensure correct connector style, thread size, and sensor output characteristics. Walker 250-23153 is a practical choice when replacing a worn oxygen sensor on a Volkswagen Golf with symptoms tied to mixture control or emissions faults.

What It Helps Address

• Check engine or malfunction indicator light related to oxygen sensor performance
• Rough running caused by inaccurate exhaust feedback
• Increased fuel consumption from incorrect air-fuel correction
• Elevated exhaust emissions from a degraded upstream sensor
• Fault codes stored in the ECU for sensor or related system issues

Installation Notes and Tips

Confirm the vehicle is a 1992 Volkswagen Golf with upstream B1S1 sensor placement before ordering. Inspect the sensor wiring harness and connector for heat damage, corrosion, or broken terminals, since physical damage can shorten sensor life and affect readings. Verify the M18 x 1.5 thread and 22 mm wrench size match the original application, and replace the sensor only after checking for exhaust leaks or other engine management faults that could influence diagnosis.

Quality Assurance

Walker Products has manufactured engine management and oxygen sensor components since 1946 and operates as an ISO 9001/TS 16949 certified company. The OE Base Sensor line is developed for specific vehicle applications and diagnostic feedback requirements, supporting accurate replacement on the 1992 Volkswagen Golf. This part cross-references Bosch (e.g., 13275) for the same application.
