As above, have asked this question several times already - car is running at half boost with all the revs. Has anyone had this code come up before and if so where can I find the offending sensor??
I have checked the Throttle Position Sensor/Idle switch and they work fine

So where exactly is the "Throttle Switch" (Code 43) and how is it different from the "Idle Switch" (Code 42)??
