Product Information
Full details
The US PRO Oxygen Lambda Sensor Socket (5516) is designed for professional mechanics and automotive enthusiasts who need a reliable tool for removing and installing lambda and oxygen sensors. Its primary benefit is the specialized cutaway design that allows for clean wire clearance, preventing damage to the sensor's electrical harness during maintenance. While it provides excellent accessibility in tight engine bays, users should note it is specifically sized for 22mm sensors and may not be compatible with non-standard sensor dimensions.

FAQs
What size is this socket?
This is a 22mm socket, which is the standard size for most oxygen and lambda sensors.
Does this socket come with a handle?
No, this is a socket tool only. It requires a 3/8-inch drive ratchet, extension, or breaker bar to operate.
Can I use this on all vehicle sensors?
It is designed for standard 22mm sensors. Always verify the sensor size on your specific vehicle before beginning work.
Why is there a slot cut into the side of the socket?
The slot allows the sensor's electrical wire to pass through the side, so you can place the socket directly over the sensor without having to remove the wire connector first.
Is the head removable?
The swivel head is integrated into the tool's design for durability and should not be removed.
Troubleshooting
Socket will not seat onto the sensor
Check for heavy carbon buildup around the sensor hex and clean with a wire brush or penetrant spray.
Socket is slipping under pressure
Ensure the socket is pushed fully onto the sensor hex and that the sensor hasn't been rounded by previous attempts.
Flexible head feels stiff or stuck
Clean debris out of the swivel joint and apply a small amount of penetrating lubricant to the hinge.
Pros and Cons
Pros
- Integrated wire clearance slot prevents harness damage
- Flexible swivel head improves access in confined spaces
- 12-point design ensures a tight, slip-resistant grip
- Durable construction suitable for professional workshop use
Cons
- Fixed 22mm size limits use to specific sensor types
- Requires sufficient clearance for the swivel head movement
- Not suitable for seized sensors requiring extreme impact force
Setup, Compatibility & Care
To use this socket, slide the sensor wire through the side cutaway slot and seat the 12-point end firmly onto the sensor hex. Ensure the tool is correctly aligned before applying pressure. This socket is compatible with most 22mm lambda and oxygen sensors found in modern computerized vehicles. To maintain the tool, wipe away any residual oil or carbon deposits after use with a clean shop rag. Keep the swivel joint lightly lubricated with a light machine oil to ensure the head remains free-moving. Store in a dry environment to prevent corrosion.
