Lambda sensor socket 22 mm 3/8" for oxygen sensor removal GEKO G02686

Lambda sensor socket 22 mm 3/8" for oxygen sensor removal GEKO G02686 is a slim, purpose-built tool designed to remove and install oxygen (lambda) sensors in automotive engines. The tool features a 22 mm hex profile and a 3/8" drive that fits common ratchets and extensions. Its narrow body provides clearance for wiring harnesses and allows access to recessed sensors without damaging the sensor body or surrounding components.

Advantages

The socket's slim design allows work in confined engine bays and recessed sensor locations while protecting the sensor harness from pinching. A 22 mm hex profile ensures a secure fit on standard oxygen sensor hexes and minimizes rounding. The 3/8" drive compatibility offers good torque control with common hand tools and extensions for improved reach. Constructed for automotive maintenance tasks, the socket balances accessibility and strength to support repeated sensor removal and installation.

Suitable for

• Removing and installing oxygen (lambda) sensors in passenger cars and light commercial vehicles
• Sensor replacement during routine engine maintenance
• Engine diagnostic and repair work where sensors are recessed or surrounded by wiring
• Use with ratchets and extensions requiring a 3/8" drive and a 22 mm sensor interface

Key specifications

• Socket size: 22 mm hex
• Drive type: 3/8" (compatible with 3/8" ratchets and extensions)
• Design: slim profile for access to recessed sensors and wiring harness clearance
• Intended use: oxygen (lambda) sensor removal and installation
• Material and finish: durable metal construction suitable for automotive workshop use

How to use

Park the vehicle on a level surface, allow the exhaust and sensor area to cool, and disconnect the vehicle battery if recommended by the vehicle manufacturer. Disconnect the sensor wiring harness, position the 22 mm socket over the sensor hex, and use a 3/8" ratchet or extension to turn the socket counterclockwise to remove the sensor. To install, thread the sensor by hand to avoid cross-threading, then tighten with the socket to the vehicle manufacturer's specified torque. Ensure wiring harnesses are routed clear of hot or moving components before reconnecting the battery.

Usage recommendations

For safer and easier work, use a suitable extension and swivel joint if access is restricted; apply anti-seize compound to sensor threads only if specified by the sensor or vehicle manufacturer. Inspect the sensor wiring and connector before installation and follow vehicle-specific torque settings to avoid damage.
