No more power after timing belt change

Hello together, I have the following problem and that: I changed the timing belt with my Volvo V40 1.8 today. I built everything apart and wanted to put the engine on OT. Then I turned the crankshaft and turned it on OT (The crankshaft) Look at the camshafts and notice that both camshafts do not cross with the Mackations… I then called in a workshop and I thought I should turn the engine on OT every time I did that… I built everything together and did a test drive…. I noticed that the Volvo has no full power anymore…. and the MIL lamp has arrived (The camshaft sensor is in the error memory!) Now I don’t think the control times are right anymore! (I checked the control times again! But the engine is 100& on OT!) And now I’m guessless…. Is there anything to do that??
