P0390 and P0394

[NotQuik]

Pretty sure I know the answer but...

Did OPG and CS then put a Whipple (Stage 2) on the car (2019). Finally started the car last night to do the first stepped rev log for Rob at PBD. Before sending the log off I noticed a CEL. Checked codes and got P0390 (camshaft position sensor “b” circuit) and P0394 (camshaft position sensor “b” circuit intermittent). Checked fuse and harness this morning as well as back side cam sensors themselves. Everything looks as it should and connections are secure.

Anything else I am missing or should check? I’m fairly certain it’s timing but would like to be sure there isn’t something else I may be over looking?

Have you done a crank relearn yet? Anytime you mess with the clutch or the crank it’s a good idea to do a crank relearn. You can do it from our ngauge or act x4.

Did you end up figuring this out? I'm having same issues. P0345 p0349 p0390 p0394

Did you do work to the engine before getting these codes or did they just show up

I installed a vmp supercharger and did oil pump gears. Then these numbers popped up. P0345 p0349 p0390 p0394

Sounds like a damaged wire or sensor

I spent a week going through all that I could and looking for anything potentially damaged or pinched before deciding to pull the front of the engine back apart. Found absolutely nothing up to that point.

Finally decided to just redo the timing as I was making no forward progress. Got it pulled apart and everything looked fine as far as I could tell (even pictures from when I did it initially showed both chains lined up properly). Since I had gone this far, I started back at zero as I didn't want to pull it apart again. Got it all put back together once again and haven't seen another light. I can only assume that it must have been a tooth off somehow.

I know it sucked but at least you are good now

I have p0394 and p0390. Replaced the sensor and did Ford tsb tsb 18-2360 and also did a kam reset. No luck. Only thing I changed within a month of this code was replacing my oem battery with an antigravity lithium battery. Had to install it sideways and kind of had to bend the things that connect to the terminals a bit. Code was weeks after battery install though. I am not sure what to do next. May try a normal type battery again but if anyone has any other suggestions that would be appreciated.

I don't think it has anything to do with the battery.

Didnt mean to revive such an old thread im in the same boat that you were in. Getting the same codes checked everything there is and its looking like ill be re timing this fucking motor. Did you happen to come across anything else before i pull this thing apart again?

Did you do the crank relearn procedure? If you are in there messing around, you really need to do it. If you do it, most of the procedures say to rev the car to 3500 rpm and it will clear, but a lot of times that doesn't work. You need to rev it up past 5000 rpm, then it will clear it.
