What is your question?
I have a load knocking top of engine. I’m getting codes p0223,p0443,p0652,p2122,p0393. I had the timing chains,phasers, and actuators replaced. I replaced the cam sensor and the cam sensor pigtail. Any help with these codes would be greatly appreciated. I was wonder what volt reading I should be getting from the cam sensor pigtail. Ty in advance
What makes this problem better or worse?
Pushing on the gas makes it tick faster

Hi - the engine noise concerns me - no matter what codes you have, engine noise is a game changer. P0223 relates to Throttle Position Sensor values P0443 relates to evaporative emissions system Purge Control Valve related concerns P0652 relates to something the engines processor is seeing P2122 relates to Accelerator Pedal Position P0393 relates to bank 2 Camshaft Position Sensor issues None of these concerns relate to anything being "out of phase" - in fact, again, I'm concerned about your engine noise before you attack these other codes. When you clear all codes, do they all come back right away like a hard fault? Sounds like P0393 is a wiring issue - short to power, causing high readings without engine operation. Check for wiring issues. Since there was work performed in the neighborhood I would check for any wiring concerns accidentally occurring.
