* 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.
