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. | Detecting Condition | Possible Cause |
P 1524 P 1525 | ● P 1524 Sensor supply voltage < 4.7 V ● P 1525 Sensor supply voltage > 5.2 V ● Engine Condition : IG ON ● Fuel Limit : YES ● Fuel Cut : NO ● EGR OFF : NO ● MIL : NO ● LIMP HOME MODE Engine speed is fixed as 1200 rpm without the accel position sensor action. | ● Open or short in circuit ● ECM |
