DTC P0230: - Fuel Pump Primary Circuit

2009 Ford Cutaway E250, 4R70WSECTION DTC P0230: - Fuel Pump Primary Circuit
DTC P0230: - FUEL PUMP PRIMARY CIRCUIT

Description:  The powertrain control module (PCM) monitors the fuel pump (FP) circuit output from the PCM. The test fails when the FP output is commanded ON (grounded) and excessive current draw is detected on the FP circuit. The test also fails when the FP output is commanded OFF and voltage is not detected on the FP circuit. The PCM expects to detect VPWR voltage coming through the fuel pump relay coil to the FP circuit.
Possible Causes: 
  • Open or shorted (FP) circuit
  • Open VPWR circuit to the fuel pump relay
  • Damaged fuel pump relay
  • Damaged PCM
Diagnostic Aids:  A concern is present when the FP_F PID reads YES. An open circuit or short to ground can only be detected with the fuel pump commanded OFF. A short to voltage can only be detected with the fuel pump commanded ON. During the key on engine off (KOEO) and key on engine running (KOER) self-test, the fuel pump output command is cycled on and off.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
