I have a 3.0 liter V6 engine with automatic transmission, and engine light on in dash. I have manuals 36071 and 10205.I hooked a Genisys machine up to truck. I get codes P1443 EVAP purge value malfunction, P1401 DPFE Sensors circuit high voltage, and P1000 OBD II monitor test cycle not complete. I can't find these codes in these manuals. I found the DPFE, will run test according to manual. Don't understand the EVAP, whats that? And of course the P1000 test is unclear. Thanks for help and suggestions.
