2010 Ford Explorer
180k miles
Engine Code: P0401
EGR PTC 89.8%
EGR Error -100.0%
EVAP PTC 60.0%
FLI 66.7%
EVAP_VP -06.54
Short 0.8
Long 0.8
So with the engine code and the above numbers, I think my fuel mixture is okay and the problem is that the EGR value fails to close? I’m curious what others may think because many moons ago I had a P0401 in a 2002 Mustang. I replaced the EGR valvue (myself) and the code remained until I sold the car. I never figured it out. 15+ years, 80 pounds and two back fusions later… I’m too old, broken and fat to be reaching into the engine turning wrenches.
I plan on taking the explorer to the percision auto tune tomorrow after work. They quoted $300 + tax for EGR replacement. However, could it be something else? I guess hoses could be cracked/loose or whatever. I’d like some advice please as I would like to appear mildly “smart” when going to the mechanic tomorrow.
Thank you!
