Location of sensor and replace
The trouble code should tell you which 02 sensor? The 02 sensors are in the exhaust, sensor 1/sensor2, whatever, bank 1/bank2, whatever, before the cat, after the cat. You have several 02 sensors in the exhaust, don't know which one?
You should be able to remove/install with proper size wrench or deep socket. They do make an 02 sensor socket that has that slot in it, not sure if you need that, though.
Testimonial: "How do i find out what bank ?no special tool what else can I use. Is it welded or clip type"
I will have to look at sensor I was given. It threw out two codes but was told they were the same sensor.....no special tool as of yet was gonna try without it....is it the weld type or clip
My info showed a front and rear 02 sensor, meaning, one before the cat converter and one after. If you replace both, it doesn't matter, if they are both the same. My info shows a special tool, w/o being able to look at it, I don't know if you need the special tool.
I don't know what you mean by weld or clipped? Most 02 sensors I've seen are threaded.
