2008 toyota tundra 5.7, 104,000 miles. I got a p0415 code. I replaced both pumps and the switching valves. Also replaced the battery and fuel cap. All fuses, including the main fusable link, and all check good with 12+ volts to each side. Now I am getting a p0415 and p0418. After warming the truck and clearing the codes the truck has never run better. If I jump the pumps directly to the battery they run fine. I am aware of the bypass kits but would prefer not use. Any ideas on what this could be? My only thought is maybe the AIP driver. Any help would be greatly appreciated.
