This AB Tools AT072 socket set is designed for professional mechanics and DIY enthusiasts working on modern vehicles. It provides specialized sockets for removing, inspecting, and replacing oxygen sensors and vacuum switches, significantly speeding up the process. A key benefit is its compatibility with both heated and non-heated sensors, and the inclusion of thread chasers for damaged threads. The primary caveat is that it requires specific knowledge of sensor types and vehicle layouts for optimal use.

The kit is designed for Titania and Zirconia oxygen sensors, suitable for both heated and non-heated types found on most modern vehicles. It also includes sockets for vacuum switches.
Yes, the 1/2" and 3/8" drive sockets are compatible with standard ratchets and extensions. The kit is also suitable for use with impact wrenches.
Select the chaser that matches the sensor thread size (M12 x 1.25mm or M18 x 1.5mm). Apply a small amount of lubricant, then carefully thread it into the damaged or dirty port using a steady turning motion to clean and repair the threads.
The set is compatible with a wide range of vehicles, including Audi, BMW, Mercedes, Peugeot, Renault, Skoda, Vauxhall/Opel, GM, and Volkswagen models equipped with standard oxygen sensors and vacuum switches.
After use, clean the sockets with a cloth to remove debris and store them in the provided blow-molded case to keep them organized and protected.
Yes, while designed for professional use, the clear functionality and included case make it very useful for DIY mechanics who perform their own vehicle maintenance.
Ensure you are using the correct socket size (22mm) and drive (1/2" or 3/8"). Verify the sensor type and vehicle compatibility. Clean any debris from the sensor head.
Ensure the correct chaser size (M12 or M18) is selected. Apply a small amount of penetrating oil or anti-seize to the threads before using the chaser. Use a steady, controlled turning motion.
Confirm the socket is fully seated on the sensor. If using an impact wrench, ensure it's set to an appropriate torque setting to avoid stripping the sensor head. Clean the sensor head and socket interior.
