Conditions for Setting the DTC
WARNING: This page is about a different car, the 2017 Cadillac ATS. However, it is still accessible from the selected car via links, so may be relevant.
P222B
- The ECM detects that the difference between the bank 2 BARO signal and the calculated BARO is greater than 20 kPa (2.9 psi) for greater than 5 s, if the vehicle has traveled at most 2.0 km (1.2 mi) since the last calculated BARO update, or the ECM detects that the difference between the bank 2 BARO signal and the calculated BARO is greater than 25 kPa (3.6 psi) for greater than 5 s, if the vehicle has traveled greater than 2.0 km (1.2 mi) since the last calculated BARO update.
OR
- The ECM detects that the bank 2 BARO pressure is less than 50 kPa (7.3 psi) or greater than 115 kPa (16.7 psi).
OR
- The absolute value of the difference between MAP and boost pressure is 10 kPa or less and between MAP and BARO 1 is 10 kPa or less and between MAP and BARO 2 is greater than 10 kPa and between boost pressure and BARO 1 is 10 kPa or less and between boost pressure and BARO 2 is greater than 10 kPa and between BARO 1 and BARO 2 is greater than 10 kPa.
P222C
The ECM detects that the bank 2 BARO sensor voltage is less than 2 V for greater than 4 s.
P222D
The ECM detects that the bank 2 BARO sensor voltage is greater than 4.5 V for greater than 4 s.
P222E
The ECM detects that the cumulative difference between bank 2 BARO sensor readings, over a specific length of time, is greater than a calibrated threshold.
