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...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2266 PID: SID 126 SPN: 1075 FMI: 4 Electric Lift Pump for Engine Fuel Supply Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the fuel lift pump 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 code becomes active whenever the ECM detects a short circuit to ground or high current in the electric lift pump circuit. Causes for this fault code are a short circuit to ground or low resistance (lift pump partially shorted). During cold weather, gelled fuel can plug the lift pump and cause this fault code. Listen to the lift pump to be sure it is running...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2272 PID: 27 SPN: 27 FMI: 4 EGR Valve Position Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage has been detected at the EGR valve position sensor 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, calibrate the ECM. Use the corresponding Troubleshooting and Repair Manual for the engine being serviced. Possible causes: 1)EGR valve position sensor wiring shorted to ground, open circuit, or shorted to power supply2)Loss of the EGR valve position sensor supply voltage or the ground circuit.3)Fuel Injector wiring harness shorted to ground, open circuit, or shorted to power supply. Possible repairs: 1)Replace the ECM.2)Replace the engine harness.3)Replace the EGR valve motor. PACCAR...
