Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
This fault code is triggered when the EGR valve is closed during an active regeneration of the aftertreatment diesel particulate filter. No failure of the aftertreatment system has occurred. Closing the EGR valve increases the exhaust temperature and speeds up the rate of regeneration of the aftertreatment diesel particulate filter. No troubleshooting of the aftertreatment system is necessary. This fault code is for information only.
No repair is necessary.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2778 PID: 289 SPN: 3481 FMI: 0 Aftertreatment Fuel Rate – Data Valid but Above Normal Operational Range – Moderately Severe Level. The lubricating engine oil needs to be changed due to possible fuel dilution.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2777 PID: 390 SPN: 3703 FMI: 11 Particulate Trap Active Regeneration Inhibited Due to Permit Switch – Condition Exists. Regeneration of the diesel particulate filter has been prevented due to the permit switch being disabled.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2765 PID: SPN: 2797 FMI: 13 Engine Injector Bank 1 Barcodes – Out of Calibration. Invalid injector barcode information has been entered.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2754 PID: SPN: 81 FMI: 16 Engine Particulate Filter Inlet Pressure – Data Valid but Above Normal Operational Range – Moderately Severe Level. Excessive black smoke has been detected exiting the engine and entering the aftertreatment diesel particulate filter.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2743 PID: SPN: 2743 FMI: 18 Aftertreatment Exhaust Gas Temperature 2 – Data Valid but Below Normal Operating Range – Moderately Severe Level. The temperatures in the aftertreatment system can not reach the required temperatures for stationary regeneration.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2742 PID: SPN: 2742 FMI: 17 Aftertreatment Exhaust Gas Temperature 2 – Data Valid but Below Normal Operating Range – Least Severe Level. The temperatures in the aftertreatment system can not reach the required temperatures for stationary regeneration.
