FAIL-SAFE FUNCTION	• Limits engine torque./ Limits the maximum engine speed. • Inhibits the automatic diesel particulate filter regeneration control. • Inhibits the manual diesel particulate filter regeneration control. • Inhibits the EGR control. • Stops the G-vectoring control (GVC). • Limits the engine transaxle total control. • Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE	• BARO sensor malfunction (integrated with PCM) • BARO sensor connector or terminal malfunction (integrated with PCM) • Malfunction in the following sensors ― MAP sensor No.1 ― MAP sensor No.2 ― Exhaust gas pressure sensor No.1 • PCM connector or terminal malfunction • PCM malfunction

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the freeze frame data/snap shot data.	—	Go to the next step.
2	VERIFY OTHER RELATED DTCs • Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) • Has any DTC related to the following sensors been stored? ― MAP sensor No.1 ― MAP sensor No.2 ― Exhaust gas pressure sensor No.1	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No	Go to the next step.
3	INSPECT BARO SENSOR • Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-D 2.2].) • Is the BARO sensor normal?	Yes	Go to the next step.
No	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. • Is the connector normal?	Yes	Go to the next step.
No	Repair or replace the connector, then go to the next step.
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED • Reconnect all the disconnected connectors. • Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)].) • Start the engine and warm it up. • Stop the vehicle, switch the ignition OFF, and wait for 20 s. • Switch the ignition ON (engine off). • Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) • Has DTC P2227:00 been recorded?	Yes	• Inspect the following sensors and perform Step 5 again. ― MAP sensor No.1 ― MAP sensor No.2 (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-D 2.2].) ― Exhaust gas pressure sensor No.1 (See EXHAUST GAS PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2].) • If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No	Go to the next step.
6	VERIFY OTHER DTCs • Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
No	DTC troubleshooting completed.
