can anyone help me find where my camshaft sensor is located

[Holden2010]

I have a Holden Commodore VE omega, I have recently replaced timing chain, Engine light went off for about 2weeks then came back on, have recently scanned it and the code that’s showing is P0019-camshaft position sensor (bank 2), intake signal faulty and P0174- mixture (bank 2) lean. I’m currently changing spark plugs and coil’s they were definitely worn. I’ve also never personally changed a sensor and wouldn’t have a clue on where it would be located.
also if anyone could help me with the code P0174-mixture (bank 2) lean means and why it keeps coming up with Stability control fault, power reduced, safety mode active on my dash that would also be much appreciated. I’m hoping that it’s just from the off spark plugs why that’s showing up on dash and loosing power, idling weird.

They are on the front of the motor.
Two on the top right and two on the top left on series 2 VE.
Series 1 has one each side of the engine with an LE0 engine or 4 with the LY7 engine but I doubt that was fitted to Omega.

They are easy to get to. 10mm bolt.
Pull out.

Replace.

Would be worth pulling out the cam actuators as well. Also held in with a single 10mm bolt. Give them a clean with some throttle body cleaner. Pop back in again.
