The computer has one of the management functions that is the voltage supply to the sensors. The sensor supply voltage 2 is fed to the APS 2 and the RPS to be used to operate the sensors.
If the ECM is reading an uncharacteristic sensor supply voltage to the APS 2 and the RPS during two driving cycles, this code will be set.
DTC NO.
