Error codes P0343 & P0368
Hello everyone,
I have run through shallow water on last Saturday 12/18/21 then after driving it smoothly for about a mile my car started vibrating. Then, I stopped at traffic light, but when I tried to take off my car lost its power. It was moving very slow. I have done few testing since then. I tested all camshaft position sensors. The two sensors on the left (Bank 2) do have about 12V but the other two CPS on the right side (Bank 1) don't have any voltage. Then I have checked all fuses in the fuse boxes and figured out fuse 23 is blown. I changed it few times but the new fuse blows up right after I install it. My understanding fuse 23 services ECM unit. I'm not sure if this blown fuse is the reason why CPS on bank 1 don't receive any power. Also, I don't know why fuse 23 keeps blowing up. Is it because a short wire? If so, how to track it? Your feedbacks are appreciated.
Thank you
