04 R53 MCS 79999 miles, quit on me the other night, all I could find was the fuel pressure regulator vacume line off. Replace FPR and fuel system has pressure, car turns over but no start. Engine codes were P0340 Camshaft Position Sensor A Circuit , P0108 Manifold Absolute Pressure High Input ,P0138 O2 Sensor Bank 1 Sensor 2 High Voltage P0130 O2 sensor Bank 1 Any help would be greatly appreciated.

Thanks
Dan

 

A bad CPS will stop the engine dead.

 

Any way to test it or just replace it?

 

When you suddenly have three different sensors throw codes at the same time, chances are that it's a ground fault in the harness versus massive sensor failures. Follow your harness around (pay attention to the one that goes under the intercooler) and look for pinched lines, damaged insulation. Check all of the grounds.
