Hi, I need help with this recurrent check engine light. I am not hearing any timing chain guide clicking sound on starting and idling but seems to have diminished power when driving the car for a few miles. I don't want to drive any further until I fix this issue. It looks like an electrical issue for me considering that all of the camshaft positioning sensors are having electrical circuit open issues. The only change I did before this is switching batteries twice in two days. I have not done a battery management reset using my GAP tool yet thinking I end up with the same battery I've been using before. Please see attached photo. Any help from the group is very much appreciated. Thank you and have a pleasant day ahead.

These are codes for your VVT solenoids (camshaft actuator, not position sensor). I agree - with all codes showing at once, appears to be electrical.

On my 2016 electrical diagram, all have a common electrical control that feeds through fuse 13E (15AMP) and relay 6E. I would suspect the fuse first and foremost.

Everyone on this forum owes the beverage of their choices* to the individuals here who regularly offer incredibly helpful feedback like this. It's kind of amazing.

I just had a similar issue, was solved by changing the entire exhaust camshaft and sprocket on bank 1 and changing the oil.

Ps. My code was P0014-71

Just an update: I have not done anything on the engine; however, I noticed that the check engine light comes on when I start the engine at any time. After I clear the check engine light with my GAP, I can drive the LR4 up to 50 miles and never have a check engine light until I turn it off and restart again. I'm pretty sure this could be electrical issue. Any idea from the group is much appreciated. Please see pics below...
