PACCAR PX-9 CM2350 (2013-17) Fault Code:1669-2 PID:203D SPN:1761 FMI:3 Aftertreatment 1 Diesel Exhaust Fluid Tank Level Sensor Circuit – Voltage Above Normal or Shorted to High Source
Posted by Diezel Solutions on
Reason:Aftertreatment Diesel Exhaust Fluid Tank Level Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at the catalyst tank level sensor circuit. Effect:Possible reduced engine performance Circuit Description:The aftertreatment diesel exhaust fluid quality sensor is a smart device that communicates to the ECM via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor performs its own internal diagnostics and reports malfunctions back to the primary engine contol module via the J1939 datalink. The aftertreatment diesel exhaust fluid quality sensor is used to measure the concentration of the aftertreatment diesel exhaust fluid in the...

PACCAR PX-9 CM2350 (2013-17) Fault Code:1677 PID: SPN:3031 FMI:4 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature Sensor – Voltage Below Normal or Shorted to Low Source
Posted by Diezel Solutions on
Reason:Aftertreatment Diesel Exhaust Fluid Tank Temperature Sensor – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the diesel exhaust fluid tank temperature sensor circuit. Effect:Possible reduced engine performance Circuit Description:The aftertreatment diesel exhaust fluid tank temperature sensor is used to monitor the temperature of the aftertreatment diesel exhaust fluid inside the aftertreatment diesel exhaust fluid tank. Component Location:The aftertreatment diesel exhaust fluid tank temperature sensor is located in the diesel exhaust fluid tank. Location of the tank and temperature sensor is OEM dependent. Refer to the OEM service manual. Conditions for Running the Diagnostics:This diagnostic...

PACCAR PX-9 CM2350 (2013-17) Fault Code:1678 PID: SPN:3362 FMI:11 Aftertreatment Diesel Exhaust Fluid Dosing Unit Input Lines – Condition Exists
Posted by Diezel Solutions on
Reason:Aftertreatment Diesel Exhaust Fluid Dosing Unit Input Lines – Condition Exists. The aftertreatment diesel exhaust fluid dosing unit is unable to prime. Effect:Possible reduced engine performance Circuit Description:The diesel exhaust fluid dosing unit lines are responsible for transporting diesel exhaust fluid between the dosing unit, dosing valve, and diesel exhaust fluid tank. Component Location:There are three diesel exhaust fluid lines. One line is between the dosing unit and dosing valve, and the other two lines are between the dosing unit and the diesel exhaust fluid tank. These lines can be partially hidden from view by the SCR system and other...
