Hello everyone need help, my car has lost boost... I'm getting this fault code:

I think it's a wiring fault, but I bought a used solenoid block, no luck. I've had a look at the wiring near the battery on solenoid plug, also seems pretty solid, cleaned up the ground wires as well. Where else should I be looking?
