Remove wheel & tire,
remove 2 torx bolts that go from the inside to the outside of the vehicle. They are on the inner side of the brake caliper.
lift the caliper out of the rotor.
remove the brake pads.
To install, you must first squeeze the caliper piston back inot its bore. Do this slowly to prevent damage to the piston. You are forcing excess brake fluid back into the master cylinder reservoir. Slow constant pressure will get the job done. Use a large c clamp or a wooden hammer handel if that's all you have.
Fit the new brake pads in the calipers and slide the assembly back over the rotor.
install the 2 torx bolts, size 40? head I think.
You are done.
If rotors are scored bad, replace them too.

The hard part is pressing the caliper piston abck into the caliper so you can get the new, thicker pads over the rotor. A large C Clamp works best.

P0325 is for the knock sensor.

P1105 is for the manifold absolute pressure sensor (MAP).

In either case diagnostic tests need to be performed to rule out faulty sensors or if something else is causing the sensors to give the computer inaccurate information.
