Frequently Asked Questions
Q: What vehicles is this 22mm oxygen sensor socket compatible with?
A: This 22mm O2 sensor socket is designed for any vehicle that uses a standard 22mm threaded oxygen sensor — which covers the majority of petrol and diesel passenger cars, SUVs, and light trucks. Always confirm your vehicle's sensor hex size before purchasing.
Q: What is the difference between the narrow slot (8mm) and wide slot (18mm) versions?
A: The narrow 8mm slot suits oxygen sensors with thinner wire harnesses or connectors, while the wide 18mm slot accommodates bulkier cables and larger connectors. Check the diameter of your sensor's wire harness or connector body to select the correct version.
Q: Can this socket be used with an impact wrench?
A: This 22mm oxygen sensor removal socket is designed for use with hand-driven 1/2" tools such as ratchet wrenches, breaker bars, extension bars, and T-handles. Using it with an impact wrench is not recommended, as excessive torque could damage the sensor threads or the socket itself.
Q: Is a ratchet wrench included with the socket?
A: No — the package includes only the 22mm slotted oxygen sensor socket. Ratchet wrenches, extension bars, and other accessories are sold separately and are not part of this listing.
