PSA for Inlet Manifold Flap Sensor replacement/code P2020

Hey guys, just a quick heads up on if (when) you need to replace your Bank 2 sensor for the inlet manifold flap, my mechanic managed to remove and replace this sensor without having to pull the manifold off.

If you aren’t already aware, the bank 2 sensor is at the back of the manifold, and there is very little room between the screws and the oil filter housing. The workshop manual doesn’t mention needing to pull the manifold to replace, but everywhere I searched on the net said it was a manifold off job. Apparently you can get a bit in there and get the screws out with everything in-situ, so hopefully this saves someone a couple of hours in the future.
