DTC P2228:00

BARO sensor circuit low input

DETECTION CONDITION
•  The PCM monitors input voltage from the BARO sensor. If the input voltage is below 1.15 V for 5 s, the PCM determines that the BARO sensor circuit has a malfunction.
MONITORING CONDITIONS
―  Battery voltage: 8—20 V
―  0.5 s have elapsed after the ignition was switched ON (engine off or on)
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
•  PCM restricts engine torque.
•  Inhibits the EGR control.
•  Inhibits the diesel particulate filter regeneration control.
•  The fast idle up correction for the idle speed control is inhibited.
•  Inhibits engine-stop by operating the i-stop function.
•  PCM restricts engine-transaxle integration control.
POSSIBLE CAUSE
•  BARO sensor (built-into PCM) malfunction
•  PCM malfunction
