Approximately 50 minutes after the ignition switch is turned off, the soak timer is activated and the values of the manifold absolute pressure sensor and atmospheric pressure sensor are compared. If the difference between the values of the manifold absolute pressure sensor and atmospheric pressure sensor is higher than a threshold value in consecutive driving cycles, the ECM will store this DTC.
