Do you need SPN number for PACCAR Engine?
It does log times in which the CELs happen which is another tool used to help diagnose. For SPN numbers to work, they require BOTH the SPN and FMI number. SPN numbers mean very little as they are not actual code numbers. Yes some SPN numbers can be converted to real code numbers but others do not compute.
What are the fault points of a Paccar mx-13?
The fault Points to VGT position erratic. Many possibilities. I would start with checking a fuses labeled ECM or engine power supply. Check power and ground supply to VGT actuator and check the resistance of the 120 ohm resistor internal to the actuator.
