DTC P2458:00 [MZR-CD 2.2]

id0102f3154100

DTC P2458:00

Diesel particulate filter regeneration duration
DETECTION CONDITION
•  The PCM calculates diesel particulate filter soot accumulation based on the exhaust gas pressure sensor signal. If the PCM calculates that soot accumulation amount is more than 10 g/L {0.6 lb/ft3}, the PCM determines the diesel particulate filter regeneration duration.
Diagnostic support note
•  FREEZE FRAME DATA (mode2) and snapshot data are not available.
•  The DTC is stored in the PCM memory.
POSSIBLE CAUSE
•  Exhaust gas pressure sensor piping restriction and/or damaged
•  Diesel particulate filter restriction and/or damaged
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA (MODE2)
•  Is the FREEZE FRAME DATA (mode2) present?
Yes
Go to troubleshooting procedures for DTC in FREEZE FRAME DATA (mode2).
(See DTC TABLE [MZR-CD 2.2].)
No
Go to the next step.
2
VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED
•  Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (mode2) and snapshot data on the repair order, then go to the next step.
3
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.
4
VERIFY DTC P242F:00 IS STORED
•  Is the DTC P242F:00 stored in PCM?
Yes
Perform DTC P242F:00 troubleshooting procedure.
(See DTC TABLE [MZR-CD 2.2].)
No
Go to the next step.
5
INSPECT EXHAUST GAS PRESSURE SENSOR PIPING
•  Inspect exhaust pressure piping for restriction and damaged.
•  Is there any restriction and damaged?
Yes
Repair or replace malfunctioning part, then go to Step 7.
No
Perform injection amount correction procedure then perform manual diesel particulate filter regeneration procedure.
Then go to the next step.
(See DIESEL PARTICULATE FILTER REGENERATION [MZR-CD 2.2])
Note
•  If any of the below DTCs are stored in the PCM, manual regeneration will be blocked by the PCM. Carry out the appropriate DTCs inspection procedure first.Then, perform manual regeneration procedure again.

*:For P242F:00, manual regeneration will only be blocked if an excessive amount of soot is in the diesel particulate filter.
6
INSPECT FOR RESTRICTION OR CLOGGED IN DIESEL PARTICULATE FILTER
•  Start the engine and warm up to normal operation temperature.
•  Monitor EXHPRESS PID using the M-MDS at idle.
•  Is the EXHPRESS PID value less than 4.0 kPa {30 mmHg, 1.2 inHg}?
Yes
Go to the next step.
No
Perform manual diesel particulate filter regeneration again.
If the EXHPRESS PID value less than 4.0 kPa {30 mmHg, 1.2 inHg}.
Visually inspect diesel particulate filter. If damaged or deterioration found, replace the catalytic converter. Clear the PCM memory.
(See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZR-CD 2.2].)
Then go to the next step.
7
VERIFY TROUBLESHOOTING OF DTC P2458:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the DTC Reading Procedure.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
No
DTC troubleshooting completed.
