My check engine lightcame on after refitting the engine after a overhaul as far as i can remember no22 refers to the knock sensor have checked the sensor and wiring harness but no fault is found.Im still running the engine in and it feels very hesitant when the turbo kisks in any help or ideas would be greatly appreciated thanks.

22 is knock sensor yes.. try an ecu reset and see if it reoccurs..

could be that one of your engine mounts is shot.. knocking through the engine etc..
