Abstract: PURPOSE: A monitoring apparatus and method of a diesel vehicle are provided to increase fuel efficiency and LNT catalyst regeneration efficiency by monitoring an air volume control unit. CONSTITUTION: A monitoring method of a diesel vehicle determines that the NOx purifying efficiency of a LNT(lean NOx trap) catalyst is in a DeNOx operating condition(S102). If yes, the air volume control is practiced after air volume and control factor of a first goal standard value are determined(S104). If the air volume control is unable to be performed with a first goal standard value within a first base time, the control factor delaying the air volume control is determined(S107). The air volume control is practiced after an air volume control target value of the control factor delaying the air volume control is reestablished(S109). If the air volume control is unable to be performed with a reset target value within a second base time, DeNOx operation of the LNT catalyst is stopped and the failure of the corresponding control factor is determined(S112).
