Error code P1349

[Liloolil]

Hi.

I am wondering if someone know common problems with a Yaris Verso 1.3L 2003 that has a orange check engine light because error code P1349?

I have recently got this error code on my car, together with one random misfire maybe once an hour. The engine light also disappears and appears randomly.

I have read that the error code means that there could be something wrong with the Valve Timing, OCV(Oil Control Valve), Variable Valve Timing controller assembly, or the ECM(Engine Control Module).

I have replaced the engine oil and oil-filter yearly, and I have never had problems with dirty oil. I am regulary checking the oil level, and have never had the level below minimum. I have also checked the OCV, and it is not covered in dirty oil.

So I am wondering if someone has been experiencing this error before, and know how to fix it? I have some experience with fixing cars, but something like taking apart the engine is too much for me.

Other information:
Model: Yaris Verso VVT-i
Year: 2003
Engine: 2NZ-FE 1.3L
Manual 5 gears
220 000km (136 700miles)
