Got a 2012 Prius non plus-in with almost 150,000 miles. When we fill the tank it takes a good 5+ minutes to fill, we have to fill it very slowly or it will splash back onto you. At about the same time we got a check engine light and our mileage dropped from 49mpg to the lower 40's/upper 30's. We had 5 codes, P043E, P043F, P2401, P2402 and a P2419, all have the same problem list. - Faulty Vacuum Pump Module - Vacuum Pump Module harness is open or shorted - Vacuum Pump Module circuit poor electrical connection - EVAP system hose (clogged, cracked or broken) - Faulty Engine Control Module (ECM) I'm currently replacing all the shocks, struts, ball joints, front bearing and usual maintenance, but would love to fix this issue at the same time. I'm looking for a illustration of these items and placement. Would love to buy a service manual, but can't find one. Any information would be greatly appreciated or a link to buy a service manual would be great.
