Alfa GT p0651 error code
I'm new here and immediately turn to you with a problem
Begin with a little background for the car.Car arrived from Italy without a drop of oil and water in it.
It appears broken turbine and leaky water radiator.
Disassembled the turbine and head.I change everything, a new cartridge,head gasket with erasers and matching valves.New timing belt, water pump and pulleys, termostat.Clean ERG and intake manifold
The problem is that when you start the engine idling holds 1500 rpm.Rpm fall only if the brake continuous or stop off clipper.
Error which gives the car is p0651 Sensor power supply 2.
Incidentally we have seen is that ERG does not work sit your 0% but no matter what rpm without error in it .
The car is 2004 AlfaRomeo Gt 1.9 jtd
I would be grateful to anyone to solve the problem
