 id0102u9751600

Note
•  To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.

Details On DTCs

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


Function Explanation (DTC Detection Outline)

•  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.

Repeatability Verification Procedure

1.  Display PID EX_FLOW_RATE (exhaust gas flow) using the M-MDS. (See PID/DATA MONITOR INSPECTION.)

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.

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.
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.


Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure
•  Step 1
―  Verify poor installation or damage between the GPF pressure sensor and the catalytic converter (gasoline particulate filter).
•  Step 2
―  Verify damage of the catalytic converter (gasoline particulate filter).
•  Repair completion verification
―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Step

Inspection

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.
―  GPF pressure sensor connection hose
•  Is the piping normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification 1.
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.
•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
―  Implement the repeatability verification procedure.
•  Perform the DTC inspection for the PCM.
•  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).
•  Perform the gasoline particulate filter data reset and perform the repair completion verification 1.
No
Go to repair completion verification 2.
Repair completion verification 1
PURPOSE: VERIFY THAT VEHICLE IS REPAIRED
•  Clear the DTC recorded in the memory.
•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
―  Implement the repeatability verification procedure.
•  Perform the DTC inspection for the PCM.
•  Is the same Pending DTC present?
Yes
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
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.
No
Go to the next step.
Repair completion verification 2
PURPOSE: VERIFY IF OTHER DTCs DISPLAYED
•  Perform the DTC inspection.
•  Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
