how do I replace the ozygen sensors on my 2005 Ranger V6 4.0?

 

you locate it first should be on your muffler youll see a wire leading to it. Unhook the wire from the sensor, then take a wrench that is the right size and turn counter clockwise (lefty loosey) and then put the new one in turning it clockwise (righty tighty)

 

lol how hard can it be dude?

but oh seriously tho, youre's might be different but mines between the two cats, nothing on the muffler...

 

Yeah their on the pipes, and you need a special tool to get it loose.. It looks like this..

 

I got them off just fine with a wrench.
