no special tool is needed, just a wrench has worked on all the EA, ER, and EJ motors i've ever done. it's tight on some, but i've always been able to get them all.

 

you unplug it first, then thread the wire/connector through the wrench to get it on the 6 points of the sensor.

 

the special tool is a socket that can work with the wire on it, has a slot in the side. no need for that though and i find the wrench more maneuverable in tight places/clearances.

odd I tried a 22 mm socket I had but the white connector would not fit but I don't understand how you could take the Oxy Sensor off without pinching the wires

Actually it's 22mm. The removal tool is usually 7/8" but it should work.

 

 

Sorry, missed the earlier responses.

 

Socket wrench won't work, you need a 22mm box wrench (The connector does fit through, right?) or open end wrench.

Little tip. Change the sensor with the exhaust system hot. Wear gloves. Hot metal expands, the hole that the sensor screws into will expand more than the threads of the sensor and it makes it easier to remove.

 

 

trust me I did.. I have a nice burn mark on my wrist..

 

I learned the hard way that the cat stays hotter longer then the rest

I always use a 7/8 box end wrench. Since the old one is always rusty - and I wouldn't want to end up using a pipe wrench. It's easier to keep it "true" when hitting it with the hammer which is often needed.

 

I also usually use Liquid Wrench instead of PB Blaster to soak the sensor down preferable when warm a time or two before attempting removal. Liek hours before. Tehn hit it with PB immediately before removal.

 

I also ALWYAS anti-seize the new one with the highest temp anti-seize that I can find.
