Im on mobile right now so cant see where you are from but cylinders 1-4 are passenger*** side in the US
Guessing on your codes id guess the intake cps on that bank. Get a new one and then take off the design cover and look at the rear of the engine. Tis held on with a torx screw and it has plug on top. Outof the 3 sensors on that side note the two similar ones. Those are the cos and installation is straight forward as you can imagine.
