SES: p0171 code
SES: p0171 code
the service engine soon light went on and the code is p0717. i know it means the truck is running too lean. i just installed CAI and exhaust, but the code went on before the exhaust went on and after the CAI went on. i noticed the hose that goes to the intake elbow on the right side was not connected, so i connected it, but i still have the code. do i need to reset anything? or was that simply not the problem. after i put in my exhaust i also noticed a funny sound that almost sounds like a leak or something. you cant hear it in park or neutral, only when driving and the fast and harder u go the sound goes faster and harder. thanks.
i had the exact thing happen to me, the code wouldnt go away for over a month. Then finally after looking for a few minutes i found a vacuum line from the intake boot was completely disconnecte. I connected it disconnected the battery for a few minutes and no more SES light!!!
yeah it was probably the same line. mine must have come off accidently when i installed my CAI. i just disconnected the battery and the SES light is gone. that out of the way, i still have a hesitation over 35 mph at very light throttle where the driver has to hit the gas almost half way for the truck to actually move. ERG?
