Verify the engine 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, calibrate the ECM. This fault code goes active when the coolant level inside the radiator top tank or surge tank drops below the sensor level. Fill the top tank with coolant. Note: It may not be possible to perform an aftertreatment diesel particulate filter (DPF) regeneration while this fault code is active. Possible repairs: 1)Add coolant to the engine.2)Replacing the coolant level sensor. PACCAR PX-8 CM2150 (2007-09) Fault Code: 196...

This fault code is logged when the ECM has detected a high temperature condition in the aftertreatment system and active regeneration of the aftertreatment diesel particulate filter is occurring. The fault code indicates that a secondary fuel source is entering the aftertreatment system and is creating a temperature increase across the aftertreatment diesel particulate filter. Possible causes: 1)Excessive engine oil or diesel fuel being introduced into the exhaust system from the engine2)A damaged engine fuel injector causing unburned diesel fuel to enter the exhaust system3)The aftertreatment diesel particulate filter outlet temperature sensor malfunctioned in-range4)A face plugged aftertreatment diesel oxidation catalyst5)An...

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. Possible causes: 1)Crankcase breather filter needs to be replaced. Possible repairs: 1)Replace the crankcase breather filter. PACCAR PX-8 CM2150 (2007-09) Fault Code: 1973 PID: SPN: 3245 FMI: 0 Exhaust Gas Temperature 3 – Data Valid but Above Normal Operational Range – Most Severe Level. The aftertreatment diesel particulate filter outlet temperature sensor reading has exceeded the maximum engine protection temperature limit. PACCAR PX-8 CM2150 (2007-09) Fault Code:...

Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe™ Online for applicable changes to the calibration stored in the ECM. If necessary, calibrate the ECM. An engine torque derate for extended EGR valve closed operation exists for this fault code. The engine torque derate for extended EGR valve closed operation operates on a time based system. The time based system will count up anytime a fault code that closes the EGR valve is active. Once the timer reaches 20 hours, an engine torque derate of approximately 15 percent will be applied. The...
