DTC P2227:00 [SKYACTIV-D 1.5]

DTC P2227:00	BARO sensor circuit range/performance problem
DETECTION CONDITION	• With the following conditions met, a condition has continued for 1.8 s within 7 to 9 s after the ignition was switched OFF in which difference between the barometric pressure and intake air pressure is 50.3 kPa {0.513 kgf/cm², 7.30 psi} or more and difference between the barometric pressure and exhaust gas pressure is 50.3 kPa {0.513 kgf/cm², 7.30 psi} or more. MONITORING CONDITIONS ― Battery voltage: 10 V or more ― The following DTCs are not detected: • MAP sensor: P0106:00 • Intake shutter valve: P1589:00 • BARO sensor: P2228:00, P2229:00 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/Snapshot data is available. • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	• Limits the engine torque or the upper limit of the engine speed. • Inhibits the auto DPF regeneration control. • Inhibits the compulsory DPF regeneration control. • Inhibits the EGR control. • Malfunction in the following sensors ― MAP sensor ― Exhaust gas pressure sensor No.1 • PCM restricts engine-transaxle integration control. (ATX) • Inhibits engine-stop by operating the i-stop function.
POSSIBLE CAUSE	• BARO sensor (built-into PCM) malfunction • PCM malfunction

DTC P2227:00

BARO sensor circuit range/performance problem

DETECTION CONDITION

• With the following conditions met, a condition has continued for 1.8 s within 7 to 9 s after the ignition was switched OFF in which difference between the barometric pressure and intake air pressure is 50.3 kPa {0.513 kgf/cm², 7.30 psi} or more and difference between the barometric pressure and exhaust gas pressure is 50.3 kPa {0.513 kgf/cm², 7.30 psi} or more.

MONITORING CONDITIONS

― Battery voltage: 10 V or more

― The following DTCs are not detected:

• MAP sensor: P0106:00

• Intake shutter valve: P1589:00

• BARO sensor: P2228:00, P2229:00

Diagnostic support note

• This is a continuous monitor (CCM).

STEP	INSPECTION	ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA • Perform the Freeze Frame PID Data Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the DTC P2227:00 on FREEZE FRAME DATA?	Yes	Go to the next step.
No	Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA. (See DTC TABLE [SKYACTIV-D 1.5].)
4	VERIFY OTHER RELATED DTCs • Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Has any DTC related to the following sensors been stored? ― MAP sensor ― Exhaust gas pressure sensor No.1	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [SKYACTIV-D 1.5].)
No	Go to the next step.
5	INSPECT BARO SENSOR • Inspect the BARO sensor. (See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-D 1.5].) • Is there any malfunction?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
No	Go to the next step.
6	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Start the engine and idle it. • Switch the ignition to off and wait for 10 s or more. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	• Inspect the following sensors and perform Step 6 again. ― MAP sensor (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-D 1.5].) ― 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 1.5].)
No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 1.5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
No	DTC troubleshooting completed.
