PACCAR PX-8 CM2150 (2007-09) Fault Code: 272 PID: SID 126 SPN: 1347 FMI: 3 Fuel Pump Pressurizing Assembly 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage or open circuit detected at the fuel pump actuator 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 when the ECM detects an open in the fuel pump actuator circuit. Causes of this fault code are a short circuit to a positive voltage or an open circuit in the fuel pump actuator circuit. If there is high harness resistance or an intermittent open circuit, Fault Code 2311 can have high inactive counts. If the fault code is intermittent, look for causes of an intermittent open circuit such as loose pins and bad connections. If the fault code is intermittent, look closely for loose wire connections at the ECM connector. Also, if the fault code is intermittent, wiggle the harness and the electronic fuel control.
Possible repairs:
1)Replace the fuel pump actuator.
2)Repair or replace the engine harness
3)Replace the ECM.
