Hi everyone!
A few months back I bought an new EGT sensor for my car.
And it worked well for a month or something.
Now It feels like its holding back while passing 4000rpm.
I have read fault codes and this came up: P1456 Exhaust gas temperature control bank 1 limit attained.
Got an idea what the problem could be?

EGTs are too high... thats what typically throws this code... assuming the sensor is ok (by 'new' I assume brand 'new' and not a new to you secondhand sensor) then high EGT's could be from a restriction somewhere like a blocked CAT...

Okay! Ofc brand new:) Then I'll try to clean out the cats. Thank you very much.
