DTC P226D:00 [PCM (SKYACTIV-X)]

Description	Gasoline particulate filter: Catalytic converter (gasoline particulate filter) poor installation or damage
Detection condition	Determination conditions	• Gasoline particulate filter pressure value is 0.54 kPa {0.0055 kgf/cm², 0.078 psi} or less (exhaust gas flow: 5.36 m³/min).
	Preconditions	• Barometric pressure: 70 kPa {0.71 kgf/cm², 10 psi} or more^1 • Engine coolant temperature: 60 °C {140 °F} or more^1 • Ambient air temperature: -10 °C {14 °F} or more^1 • Engine speed: 500 rpm or more^1 • Exhaust shutter valve angle: 66.5 ° or more (Australian, European (L.H.D. U.K.) specs.) • Exhaust gas amount: 5.36 m³/min or more • The following DTCs are not detected: ― GPF pressure sensor: P2452:00, P2454:00, P2455:00 or P2456:00 ― MAF sensor: P0100:00 or P060F:00 ― Exhaust shutter valve position sensor: P26C5:00 or P2BF5:00 (Australian, European (L.H.D. U.K.) specs.) ― Internal PCM malfunction: P16AB:00 ^*1: Standard can be verified by displaying PIDs using M-MDS
	Drive cycle	• 1
	Self test type	• CMDTC self test
	Sensor used	• GPF pressure sensor • MAF sensor
Fail-safe function	• Stops the EGR control.
Vehicle status when DTCs are output	• A message related to the gasoline particulate filter is indicated on the display. • Poor acceleration • Graphite is generated.
Possible cause	• Poor installation or damage between the GPF pressure sensor and the catalytic converter (gasoline particulate filter) ― Housing component ― EGR pipe ― GPF pressure sensor connection hose ― EGR cooler • Catalytic converter (gasoline particulate filter) damage • PCM malfunction

• Indicates that poor installation or damage of the catalytic converter (gasoline particulate filter) has occurred and soot is discharged instead of being accumulated in the gasoline particulate filter.

• If the GPF pressure sensor output value is abnormally small in relation to the exhaust gas flow, the PCM stores a DTC.

2. Drive the vehicle at a high engine speed and a high vehicle speed for a continuous 5 min so that the PID EX_FLOW_RATE value reaches 150 kg/h or more.

Step	Inspection	Results	Action
1	PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY • Verify related Service Bulletins, on-line repair information, or Service Information availability. • Is any related Information available?	Yes	Perform repair or diagnosis according to the available information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION • Record the freeze frame data/snapshot data. Note • Recording can be facilitated using the screen capture function of the PC.	—	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

• Repair completion verification

Step	Inspection	Results	Action
1	PURPOSE: VERIFY PIPING BETWEEN GPF PRESSURE SENSOR AND CATALYTIC CONVERTER (GASOLINE PARTICULATE FILTER) • Visually inspect the piping between the GPF pressure sensor and the catalytic converter (gasoline particulate filter) for poor installation or damage. ― Housing component (See SUPERCHARGER REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) ― EGR pipe (See EGR PIPE REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) ― GPF pressure sensor connection hose (See GPF PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) ― EGR cooler (See EGR COOLER REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) (See CATALYTIC CONVERTER (GPF) REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) • Is the piping normal?	Yes	Go to the next step.
1		No	Repair or replace the malfunctioning location and perform the repair completion verification 1. (See CATALYTIC CONVERTER (GPF) REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
2	PURPOSE: DETERMINE IF MALFUNCTION CAUSE IS GASOLINE PARTICULATE FILTER • Install/connect the part removed/disconnected during the troubleshooting procedure. • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ― Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is the same Pending DTC present?	Yes	Malfunction due to poor installation or damage of the catalytic converter (gasoline particulate filter) can be considered. • Replace the catalytic converter (gasoline particulate filter). (See CATALYTIC CONVERTER (GPF) REMOVAL/INSTALLATION [SKYACTIV-X 2.0].) • Perform the gasoline particulate filter data reset and perform the repair completion verification 1. (See GASOLINE PARTICULATE FILTER DATA RESET [SKYACTIV-X 2.0].)
2		No	Go to repair completion verification 2.
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ― Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. • If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
Repair completion verification 1		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED • Perform the DTC inspection. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
Repair completion verification 2		No	DTC troubleshooting completed.
