Remove and clean your Oil Control Valves, and the chamber they fit in.
they are located on the front of each cly. head. SEE photos:
I used mechanical fingers pinching a small rag soaked in carb cleaner to clean the chambers, because they are flexible. IF cleaning fails you might have to replace them (I didnt) just cleaned them REAL good.
good luck with yours..

is the problem from the battery, and needed replacement.
is this true??
"the low voltage caused problems in the computer, reading bad values from sensors and really screwing it up."

this is copied from another post: 2002 Camry: 4cyl.
The only code I ever got is 1656: OCV circuit malfunction. A technician checked and said it was caused by a poor grounding. That code has not returned since then (a few days back). However, I'd still place OCV on the list:
all of my repairing has been on P1345...... I am not sure what P1656 is, or how to locate it.
P1656 OCV Circuit Malfunction (Bank 1)
P1345 VVT Sensor Circuit Malfunction (Bank 1)
