Default Reduced Engine Performance

Hi, 2004 S60 2.4 no turbo
last codes were PO123 & PO600
So the APS was changed it was running smooth for about a week and it reduced engine performance again and gave code PO600 serial communication link with no pending codes. HELP

the P0123 is saying the throttle position sensor is out of range/missing and the P0600 says there was a general serial comms link error which gets set when the ECU sees a missing signal from a set of devices. The latter suggest you may have a wiring issue on the connectors which includes the TPS. Not sure what you mean by "APS was changed" - did you mean TPS?
