Answer 1

HI there

This code is fairly straight forward and indicates an issue with the FPDM. This won't affect the fuel mileage, but it can cause issues with power on acceleration. The FPDM will increase voltage to the fuel pump when the car is running in various conditions providing more fuel pressure when it's needed.
