I put all new sensors in 07 rebuilt, for the 09 engine. I didn't put 02 sensors in new, and the cmp from 07 head, I used it to seal the hole for no leak, beings no wires for cmp. The rebuild didn't run right, first I took old 07 exhaust camshaft position, sensor, and put it in the rebuild, still didn't run right, so I put a new 07 position cam sensor in, run a little better but not right. The only that different between the 07, and 09, was the 2 sensors the head, and the actuator on the exhaust cam. I mic the exhaust camshaft actuator, and there was several thousands different, I figured if it didn't run right with 09 sensor, I would put 07 sensor in the rebuild. I'm getting a p0365, and p0366 codes. And I don't drink....

'09 pcm requires '09 sensors.

If you verified '09 cmp and ckp in the '07 are good and secured clean wiring/ contacts/connections, next step would be to swap the actuator engine timing camshaft sprocket (12589782).
