DTC: P244A
EN01H16F01030F03001145
P244A: Filtering performance (missing substrate)
INFORMATION [missing substrate]
1. Technical description
•
ECU constantly calculate and accumulate the amount of soot emission from the engine.
•
Based on the values of the differential pressure sensor and the DPR temperature sensor, ECU detects clogging and
erosion of the DPR.
<Description of malfunction>
•
Abnormal drop in differential pressure in DPR part is detected.
2. DTC set condition
(1) DTC detection condition
•
The engine must not be stopped.
•
After automatic regeneration
•
Burner in inactive status
•
Calculated exhaust gas flow rate of 205 L/s or higher
•
Exhaust brake is inactive.
