DTC P2228:00 [SKYACTIV-D 1.5]

id0102q2153200

DTC P2228:00

BARO sensor circuit low input

DETECTION CONDITION

•  The PCM monitors input voltage from the BARO sensor. If the input voltage is below 1.17 V for 5 s, the PCM determines that the BARO sensor circuit has a malfunction.

MONITORING CONDITIONS

―  Battery voltage: 8—20 V

―  0.5 s have elapsed after the ignition was switched ON (engine off or on)

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.

•  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

Diagnostic Procedure

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.
2		No	Go to the next step.
3	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].)
3		No	Go to the next step.
4	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [SKYACTIV-D 1.5].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
4		No	Go to the next step.
5	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].)
5		No	DTC troubleshooting completed.
