Hello All , I decreased engine and did not disconnect battery and cleaned throttle body and MAF sensor. Let it dry after hosed down degreaser. Idled high and then today check engine light came on. I put OBD sensor and two (2) codes pooped up P0393 and P0390. I then disconnected negative terminal in battery and let sit for an hour. I then started the truck and check engine light off . I waited then started it again and check engine light went on. I hooked up OBD ll and only one (1) code came up P0390. It idles a little rough. The P0390 says Camshaft Position Sensor B Circuit Bank 2. Where is that sensor located and did I short it out . Or can I take it out and test it with a Voltameter. Please send picture of where it is located big please I wear glasses.
