DTC P2228 00: BARO Sensor Circuit Low Input: Notes

DTC P2228 00 DETECTION CONDITIONS AND POSSIBLE CAUSES (SKYACTIV-G 2.0, SKYACTIV-G 2.5)

DTC P2228:00	BARO sensor circuit low input
DETECTION CONDITION	The PCM monitors input voltage from the BARO sensor. If the input voltage is low for 5 s , the PCM determines that the BARO sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Fixes the barometric pressure for the engine control at 101.32 kPa {1.0332 kgf/cm ² , 14, 695 psi} .
POSSIBLE CAUSE	BARO sensor (built-into PCM) malfunction PCM malfunction
SYSTEM WIRING DIAGRAM	Not applicable

CAUTION:

Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
