DTC P2229:00

BARO sensor circuit high input

DETECTION CONDITION

• The PCM monitors input voltage from the BARO sensor. If the input voltage is above the specified value 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/cm², 14.695 psi}.

POSSIBLE CAUSE

• BARO sensor (built-into PCM) malfunction

• PCM malfunction
