Why does this corolla ping on acceleration (3ZZ-FE). on 2007 Toyota Corolla

The timing chain was changed. We rechecked the valve timing. we did a cylinder leakage test, readings within spec. What i noticed was the spark plugs are burning white, like the vehicle is running lean. Spark plugs are for the vehicle according to vehicle manufacture. Came up with fault code "camshaft position sensor out of phase" and now comes up with VVTi sensor problem. From experience when these faults come up it means that the valve timing is off, but like i said the valve timing is spot on.

the cam phaser may be set wrong and causing this cam sensor circuit 1st then cam sensor for plugged oil passage
I did check the phase sensor VVT-I sensor it was clean, none the less i cleaned it and the small strainer. What i found also was the timing chain tensioner had silecone blocking the oil gallery, which i also cleaned. The cam sensor is megnatic and has no oil galleries.
