Abstract
A method for controlling an engine for a vehicle to ensure a stable driving state of the engine on an electrical failure of a Purge Control Solenoid Valve (PCSV) may include determining, by a controller, whether a situation of an electrical failure where an opening state of the Purge Control Solenoid Valve (PCSV) is held is detected, increasing, by the controller, a failure detecting counter to a first reference value according to a state where the situation of the electrical failure of the PCSV has been detected is kept as a result of performing the failure detecting, and compensating, by the controller, a rotation number of the engine to increase the rotation number of the engine when the failure detecting counter exceeds the first reference value as a result of performing the increasing.
