No one has suggested simply pulling the VCT connectors ( both of them ) resetting KAM, doing a drivecyle and reassess. as a go-nogo test. Swap senors to see if code moves is another trick.
Cam position sensors can be removed and inspected - any sludge will be evident on their tips. Removing a valve cover will also work. Swap sensors to see if code moves as well.
Sludge - only effective method is Auto-Rx - and that procedure takes a long while to rid the engine of accumulation if any.
Lastly - the VCT solenoid valve bodies are often overlooked for accumulation. Takes some work to remove and inspect/clean.
If the code persists despite trying the low-hanging fruit, be prepared to dive under that front cover....
