Hello

I had electric problems before
( https://volvoforums.com/forum/volvo-...m-78434/page2/ )

And again car has lack of power.According to bosch diagnostic (code 223) problem is with gas pedal.

P0223 -- ECM-922C (volvo code) -- Electronic throttle unit, potentiometer 2 -- Signal too high

They gave in an used gas pedal,so change with another one (now is think a new one will be better solution) will help or it could be something else?

Another error code 2263 triggered when i was driving to the hill, car had around 2000/2100 rpm in 5 shift and no grip,than computer shown SYSTEM ENGINE SERVICE REQUIRED.Fast shifted down to 4 increase rpm to 3000 and again to shift 5.Car was going normaly.I know that error code sould by also solved soon as possible.

By next day car had lack of power with those two codes.
One week before was changed EGR valve (brand new)

Any advice?What i have to look? mass air flow (maf),map sensor,air/fuel filter?

 

Another code came out

P2566 - Turbocharger Boost Control Sensor -Signal Missing
It looks that it have something to do with error code 2633.

What is that sensor?Is it MAP or what?
