VTCS Solenoid Valve harness is open or shorted
VTCS Solenoid Valve circuit poor electrical connection
My experience has been wiring and connector terminal problems cause more electrical problems than the sensors and valves. These codes refer to detecting electrical circuit faults, not mechanical problems which are caused by valves. Also, when there are two codes referring to electrical problems, start by suspecting they have a common cause.
We do not get involved with costs here because there are way too many variables. We do not even know what is wrong yet, or how long it will take to find the causes of the problems or repair them.
