Order of inspection
P0148 Fuel Delivery Error High
The P0148 code means the amount or pressure of fuel delivered does not match what the computer asked for. It shows up mostly on diesel engines and is usually caused by a clogged filter, air in the fuel system or a weak pump. You can drive with caution, but the engine can lose power suddenly.
