Fuel Pressure System Diagnosis



Fuel Pressure System Diagnosis

New fuel pressure system diagnosis function is implemented. It is due to new hardware design for this model year, with a variable fuel pump, a fuel pressure sensor and a fuel temperature sensor. The function target is to be able to point out the fuel pressure system as incorrect due to performance specification and fulfill legal requirements. The function will detect the fuel pressure to be stuck high (higher pressure than target), stuck low, noisy pressure signal or plausibility.

The function, fuel temperature sensor diagnosis will detect min and max error.

The function, fuel pressure sensor diagnosis will detect min and max error.

And the function fuel power stage diagnosis will detect min, max and signal error.
