PACCAR PX-6 CM2150 (2007-09) Fault Code: 2265 PID: SID 126 SPN: 1075 FMI: 3 Electric Lift Pump for Engine Fuel Supply Circuit – Voltage Above Normal or Shorted to High Source. High voltage or open detected at the fuel lift pump signal circuit.
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 becomes active if the ECM detects an open circuit at key-on. Causes of this fault code include an open circuit in the electric fuel lift pump circuit.
If the fault code is intermittent, look for causes of an intermittent open circuit, such as loose pins and bad connections. At key-on, the lift pump duty cycle ramps to 100 percent. This fault code can detect open circuit conditions only at key-on. The lift pump only runs at key-on and during cranking to aid in priming of the gear pump.
Possible repairs:
1)Replace the electric fuel lift pump.
2)Repair or replace the engine harness.
3)Replace the ECM
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2198 PID: SID 027 SPN: 641 FMI: 11 VGT Actuator Driver Circuit – Root Cause Not Known. Intermittent communication between the smart VGT controller and the ECM has been detected. The VGT controller is not interpreting the J1939 message from the ECM correctly.
