a little update
everything checks fine, good signal from all sensors and to all coils and injectors.
but ignition advance check with stroboscope light shows advance sometimes fine, sometimes jumping to .. let's say -30 degree more. I couldn't finish the check because my stroboscope died, purchased new one, tomorrow with fresh head.
some ideas what can cause advance jumps? cam and crank signal checked at pcm connectors, seem perfect, constant and ignition power supply ok, ground ok. maybe something wrong inside tcm? may loosed timing chain cause this without making noise? engine perfectly quiet, only sound injectors clicks. any ideas?
Cam sensor is an inexpensive repair. I've seen a few do this similar thing with no codes. It does affect your timing!
You try cycling the key 3 times and leaving on 3rd time? Sometimes dataloggers won't pick up all DTCs
