Greetings!
Background: CEL on. P0171 and P0174 with P0401 and P0442 as added bonus! Hooked up to full version of forscan and it shows a 0 psi reading for my tank pressure. Do forscan or explorers (2002 v6 vinE) have that sensor or is mine bad or is a monumental leak likely?
If anyone can make sense of the other readings...please opine.
More background: I smoke tested engine and found leak near EGR valve appearing to be from underside of diaphragm opening. replaced it with a new one i bought several years back when i actually needed the dpfe sensor. also replaced throttle body gasket, IAC gasket and EGR tube gasket as well.
Cleaned MAF with correct fluid but am considering R&R of it as well as evap purge solenoid near master cylinder.
Hate throwing parts at it but at this point...need to get it to pass inspection.
Thanks to all!
