After a timing belt change in my S40 2008 5 cyl non turbo, I have ECM-640A code, according to my mechanics they have checked twice the setting of the belt and it is OK.
According VIDA I have the following values at idle, that I would like someone help me to understand

ECM Camshaft adaption, inlet 27,20 CA
ECM Camshaft shifting angle ,inlet 0,17 CA
ECM Camshaft reset valve, inlet 834,57 mA
ECM Camshaft advance angke, inlet nominal 17,18 CA

Is too low the value for shifting angle inlet ? I have checked the solenoid applying 12 volt and it works, also I cleaned it. I have lack of power when you accelerate and a roar sound, normal driving you do not notice almost nothing
I would appreciate any help

 

some good info in this thread:

Thanks for the information, now I have run around 80 km with no code, but still the car is slow when you accelerate.
I have checked the solenoid valve unistalled, I apply 12 volt and it open and close, then I installed it again and measure the voltage applied when you start the car and there is 12 volt applied on the solenoid valve.
I am thinking the only thing should be the timing belt, in spite that my mechanics checked it twice, one teeth is enough to loose power to and get roar sound when you force a little the engine? Driving normal the engine is very smooth also at idle.
I would appreciate any comments

have you measured the resistance across the two terminals on the solenoid? You should get somewhere in the neighborhood of 7ohms.

 

Yes I measured it, it is around 8 ohm
