Review on TEKTON 3/8 Inch Drive x 7/8 Inch Offset Oxygen Sensor Socket - 6-Point, Model 47749 by Carlos Block

I just replaced my oxygen sensor at 18. old RAV4. If the sensor has been there for a long time, this tool will not pull it out. As others have said, if you try to apply too much torque to it, a slot will open up on opening. To remove a stuck sensor: 1) Use a vise to pry the sensor off the base (or enough to complete step 2). 2) Use a 22mm or 7/8 inch deep socket and pry bar or ratchet if there is no room to align the breaker. Hit it with a big hammer (small sledgehammer) and pull like crazy. 3) Mine was fully tightened with all of the sensor threads remaining in the manifold plug. 4) Clean the threads in the manifold. I had to use a faucet (M18x1.50) to clean out a few threads and then used a thread cutter (the thread cutter takes about a thread to get started.) 5) This tool comes in very handy for installing a new sensor.
