4	INSPECT BARO SENSOR CONNECTOR FOR POOR CONNECTION Disconnect the BARO sensor connector. Inspect for poor connection (damaged/pulled-out pins, corrosion, etc.). Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 9.
4		No	Go to the next step.
5	INSPECT BARO SENSOR MALFUNCTION Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION .) Is the BARO sensor okay?	Yes	Go to the next step.
5		No	Replace the BARO sensor, then go to Step 9.
6	VERIFY BARO SENSOR SIGNAL CIRCUIT FOR SHORT TO REFERENCE VOLTAGE CIRCUIT Measure the voltage between BARO sensor terminal A and body ground. Is the voltage above 4.43 V?	Yes	Repair or replace short to power supply, then go to Step 9.
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION Disconnect PCM connector. Inspect for poor connection at terminals (damaged/pulled-out pins, corrosion, etc.). Is there malfunction?	Yes	Repair the terminal, then go to Step 9.
7		No	Go to the next step.
8	VERIFY BARO SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Inspect for continuity between the following terminals: Between BARO sensor terminal A and PCM terminal 1AG Between BARO sensor terminal B and PCM terminal 1AA Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness for open circuit, then go to Step 9.
9	VERIFY TROUBLESHOOTING OF DTC P2229 COMPLETED Make sure to reconnect all disconnected connectors. Turn the ignition switch to the ON position (Engine off). Clear the DTC from the PCM memory using the WDS or equivalent. Start the engine. Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION .)
9		No	No concern is detected. Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE Perform "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ) Is any DTC present?	Yes	Go to applicable DTC inspection. (See DTC TABLE )
10		No	Troubleshooting completed.
