Conditions for Setting the DTC: P2430

The ECM determines that the pressure sensor value change is less than a calibrated value.

P2431

• The ECM determines that the difference between the AIR pressure sensor and the barometric pressure (BARO) sensor signals is greater than 10 kPa when the AIR pump is commanded OFF.

  OR

• The ECM determines that the difference between the AIR pressure sensor and the BARO sensor signals is greater than 50 kPa when the AIR pump is commanded ON.

P2432 

The pressure sensor signal is less than 0.2 volt for at least 12.5 seconds.
