DTC P2229-00: BARO Sensor Circuit High Input: Notes

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/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.
