P2294-FUEL PRESSURE SOLENOID OPEN CIRCUIT

For a complete wiring diagram Refer to Section 8W

• When Monitored:

  With the ignition on and the ECM Fuel Pressure Solenoid command off.

• Set Condition:

  The ECM does not detect voltage on the Fuel Pressure Solenoid Control circuit for 0.28 second.

Diagnostic Test

NOTE: If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.

NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC.

WARNING: HIGH-PRESSURE FUEL LINES DELIVER DIESEL FUEL UNDER EXTREME PRESSURE FROM THE INJECTION PUMP TO THE FUEL INJECTORS. THIS MAY BE AS HIGH AS 23,200 PSI (1600 BAR). USE EXTREME CAUTION WHEN INSPECTING FOR HIGH-PRESSURE FUEL LEAKS.

WARNING: FUEL UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE SKIN CAUSING PERSONAL INJURY OR DEATH. INSPECT FOR HIGH-PRESSURE FUEL LEAKS WITH A SHEET OF CARDBOARD. WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE CLOTHING WHEN SERVICING FUEL SYSTEM.

NOTE: An open ASD power supply to the ECM will cause multiple DTC's including this DTC to set.

NOTE: Check the ECM for other DTC's. If other DTC's are set with this DTC refer to the symptom list and perform the CHECKING THE ECM POWER AND GROUND CIRCUITS test before continuing.

NOTE: The scan tool should display P2294-FUEL PRESSURE SOLENOID OPEN CIRCUIT.

NOTE: The scan tool should display P2296-FUEL PRESSURE SOLENOID SHORT CIRCUIT.
