With the right design, even the most stubborn exhaust sensors can be removed without hassle. The CTA 2227 Exhaust Gas Sensor Socket Set delivers the durability, access, and leverage technicians need to tackle emissions-related repairs efficiently and safely.
Remove Stubborn Exhaust Sensors with Confidence
Servicing exhaust gas sensors can be one of the more frustrating jobs in the shop. High heat, corrosion, tight clearances, and delicate wiring harnesses often turn a routine repair into a time-consuming task. The CTA 2227 Exhaust Gas Sensor Socket Set is designed to simplify that process, giving technicians the tools they need to remove and install sensors quickly, safely, and with confidence.
Built for Real-World Exhaust Service
Exhaust sensors such as O2, NOx, and EGT sensors operate in extreme environments. Years of exposure to heat cycles, road debris, and moisture can cause sensors to seize in place, while the attached wiring harness limits access and increases the risk of damage during removal.
The CTA 2227 set is purpose-built to address these challenges. Its side-slot socket design allows technicians to slide the socket over the sensor wiring, eliminating the need to disconnect the harness. This saves valuable time and helps prevent accidental wire damage during service.
Each socket is engineered to maintain full hex engagement with the sensor, reducing the chance of rounding or slipping when dealing with stubborn or corroded components.

Key Features
The CTA 2227 Exhaust Gas Sensor Socket Set includes five commonly used sizes to cover a wide range of applications:
-
14mm, 17mm, 19mm, 22mm, and 24mm sockets
-
Side-slot design for access without disconnecting the wiring harness
-
Dual 1/2" internal drive for ratchets and breaker bars
-
24mm and 30mm external wrench drive for additional leverage when needed
-
Chrome molybdenum steel construction for durability and strength
-
Black phosphate finish for corrosion resistance
-
Organized EVA foam tray for easy storage and tool control
This combination of features provides flexibility when working in tight exhaust spaces and when extra torque is required to break loose seized sensors.

Why It Matters
Exhaust sensor service frequently involves limited access and heavily corroded threads. Using the correct socket ensures proper engagement with the sensor hex while protecting the attached wiring.
With the CTA 2227, technicians can:
-
Use a 1/2" drive ratchet for standard removal and installation
-
Add a 24mm or 30mm wrench for increased leverage when sensors are seized
-
Maintain control while protecting the sensor harness
The result is a faster, more controlled repair with reduced risk of damaging expensive components.
