And later I read some threads about camshaft adjustment....
I got this from my car....below:

I do not know about specs...
What does this mean? and What can I do? Is my car ok? It runs funny, though....

If anybody has an idea to crack this code...means explain...please.

Thank you for your help.

Cam sensors! Special tool required to fix. Seems to always take service longer than they think... probably waiting for the tool.

Thank you for your reply.
The complication of the problem went suddenly easy thing.
I took the car to a dealer to check other things such as leakage on sealings and gskets. I have 150,000 miles on the car already. So, I thought that is a good time to check them.
And they suggested me to change filter and spark plug. Because I never change them since I bought the car which is 2007. I know... I travel a lot, over the mountains, cross the sandy field, dusty country roads and some time cross the little creeks. No one, include dealer, ever mention about it. So, anyway I changed filter and I also cleaned the spark plugs, there was some deposits. And gusee what, everythings are fine. My car runs so smooth and feel so light, no glumbling, gagling or shaking. No problems with anything for now.

If the car give me the same code again then, I will go with your advice. Thanks.

There's a TSB for the fuel pressure sensor where the sensor is known to get fuel intrusion into the sensor causing malfunction. TSB 2015106/8

Thank you for the info. I will check the issue with dealer so, they can do it under warrenty.
My warrenty expired an year ago. And now it has 150,000miles on it. It is very questionalble but worth a shot. And actually, I wanted to know what is the ptoblem, so I can fix it, if it is fall on to my capability.
Hope that no problem as long as it can be.

I appreciate you, again.
