EVAP trouble code question
the other day, my truck tripped a trouble code, 1441 (i think - im at school right now), says something like "EVAP flow during non-purge." So i talked to the local chevy dealer, and they said that theres a leak somewhere in the EVAP system. anyone else had this problem?
also, my understanding of this system is that when pressure from fuel vapor builds up in the gas tank, this system kicks in and bleeds off the pressure into the intake manifold via a solenoid controlled valve. is this correct?
