Socket wrench for Lambda/Oxygen sensor 22 mm 1/2" drive Jonnesway AI010033

Jonnesway socket wrench for Lambda/Oxygen sensor 22 mm with 1/2" drive is a dedicated hand tool designed for removal and installation of oxygen sensors in vehicle exhaust systems. The 22 mm hex size matches common sensor hexes and the 1/2" square drive accepts standard ratchets or breaker bars, enabling secure grip and torque transfer when working in confined engine-bay or underbody locations. The tool is intended for professional workshops and home mechanics who service passenger cars and light trucks.

Advantages

The socket's open-ended profile and 22 mm fit allow access to sensors with wiring harnesses without disconnecting or damaging the cable. Compatibility with 1/2" drives provides robust leverage for loosening seized or tightly torqued sensors. Constructed for repeat use, the socket delivers consistent engagement on sensor flats and reduces rounding risk compared with improvised tools.

Suitable for

• Removing and installing oxygen (lambda) sensors on passenger cars
• Servicing light commercial vehicles and small trucks
• Automotive repair shops performing exhaust diagnostics and replacements
• DIY mechanics doing periodic emissions-related maintenance

Key specifications

• Socket size: 22 mm hex fit suitable for standard oxygen sensor flats
• Drive type: 1/2" (12.7 mm) square drive for ratchets and breaker bars
• Profile: open or cut-away design to accommodate sensor wiring
• Material: hardened steel construction for durability and torque resistance
• Finish: corrosion-resistant surface treatment for workshop environments

How to use

Fit the 22 mm socket over the sensor hex while routing the wiring through the cut-away opening so the cable is not pinched. Attach a compatible 1/2" ratchet, extension, or breaker bar to the square drive. Apply steady, controlled torque to loosen the sensor counterclockwise; use penetrating lubricant first if the sensor is corroded. When installing, thread the sensor by hand initially to avoid cross-threading, then tighten to the manufacturer's specified torque using the socket and drive.

Usage recommendations

Use the correct 22 mm socket size and a 1/2" drive tool to prevent damage to sensor flats. If access is limited, combine with appropriate-length extensions or universal joints. Wear eye protection and gloves when working under the vehicle, and follow vehicle manufacturer torque specifications for installation.
