Conditions for Setting the DTC

P2430

• The measured AIR pressure change does not meet expected pressure changes during AIR pump phase 1 or phase 2 operation.
• DTC P2430 sets within 8 seconds when the above condition is met.

P2431

• The PCM 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 PCM 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.

P2433

The pressure sensor signal is more than 4.8 volts for at least 12.5 seconds.
