P2230



* DTC P0068, P0101, P0102, P0103, P0106, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0222, P0223, P1516,



P2135, P2228, or P2229 is not set.



* The engine is running.



* DTC P2230 runs continuously when the above conditions are met.



Conditions for Setting the DTC



P2227



* The engine is running.



* The ECM detects that the difference between the BARO signal and the calculated BARO is greater than 15 kPa (2.2 psi) if the vehicle has



traveled at most 0.5 km (0.31 mi) since the last calculated BARO update, or the ECM detects that the difference between the BARO signal



and the calculated BARO is greater than 25 kPa (3.6 psi) if the vehicle has traveled greater than 0.5 km (0.31 mi) since the last calculated



BARO update.



OR



* Ignition ON, engine OFF



* The ECM detects that the BARO pressure is less than 50 kPa (7.3 psi) or greater than 115 kPa (16.7 psi).



P2228



The ECM detects that the BARO sensor voltage is less than 1.95 V for greater than 4 s.



P2229



The ECM detects that the BARO sensor voltage is greater than 4.5 V for greater than 4 s.



P2230



The ECM detects that the difference between the current BARO sensor reading and the previous BARO sensor reading is greater than 10 kPa (1.5



psi).



Action Taken When the DTC Sets



DTCs P2227, P2228, P2229, and P2230 are Type B DTCs.



Conditions for Clearing the MIL/DTC



DTCs P2227, P2228, P2229, and P2230 are Type B DTCs.



Diagnostic Aids



Inspect the inlet port on the BARO sensor for moisture or debris and attempt to dry or clean the inlet, if contaminated.
