DTC Parameters

DTC will set if any of following conditions are met for 15 seconds:

• A/C refrigerant pressure sensor voltage is less than 0.2 volt (3 psi), IAT is more than 32°F (0°C) and DTCs P0112 and P0113 are not set.
• A/C refrigerant pressure sensor voltage is less than 0.1 volt (zero psi) and IAT is less than 32°F (0°C)
• A/C refrigerant pressure sensor voltage is more than 4.94 volts (446 psi) and PCM has received an A/C request from BCM.
• A/C refrigerant pressure sensor voltage is more than 4.0 volts (358 psi) and PCM is not receiving an A/C request from BCM.
