Question about Cars & Trucks
My van displays P0440 and P0441 codes. I understand this has to do with incorrect emissions purge flow. I have already replace the fuel cap... no luck. Had it inspected by dealership and they noticed moisture in the lines. Should I replace the NVLD Pump and Solenoid or one or the other? Where are these located? Is it difficult to do myself, or should I have a mechanic do it? How much time should it take?
