OK so I've got a P0141 code fault.
Bank 1 sensor 2.
Bit confused as to which one it is I know it's one of the pre cat ones but which ?
When looking at the engine from the rear of the car, is it LEFT or RIGHT ?
one word answers please 😊😊😊
Neither
Bottom.
Really? So it's the post cat sensor ?
Use as many words as you like lol 🙂
Easily found by googling... Bank 1/1 on right. Bank 2/1 on left. Bank 1/2 is post-cat.
Cheapest way to fix is a 4-wire sensor with a long enough cable & crimp the Toyota plug onto it.
Don't buy a cheap sensor even if it does say 5 year guarantee.....
Are all 3 sensors the same apart from cable length ? I've already ordered a DOX0204 which as I understand fits the top two ?
M18 x 1.5mm thread O2. That's it. Keep the old one for the plug.

Correct. DOX0206 = the longer cable version.
if it's the lower O2 sensor, two things:
1) you'll need the longer cable length
2) you'll need a big 22mm spanner (not the normal O2 socket)
check my thread on this previously - Caroline (and myself+others) went into a lot more detail on parts, tools, locations, etc...
