Disclosed is a common rail fuel injection control apparatus that is used in an engine that drives power equipment, an actual measurement temperature difference that is a difference between a pre-pressurization temperature of the fuel and a post-pressurization release temperature of the fuel is obtained, and it is determined that a pressure sensor is failed when an absolute value of a difference between a representative temperature difference set in advance as a difference between the pre-pressurization temperature of the fuel and the post-pressurization release temperature of the fuel, and the actual measurement temperature difference exceeds a predetermined threshold value.
