Possible causes

  • Faulty Low Speed Fuel Pump
  • Faulty Fuel Pump Relay
  • Low Speed Fuel Pump harness is open or shorted
  • Low Speed Fuel Pump circuit poor electrical connection
  • Damaged Powertrain Control Module (PCM)

Tech notes

The Powertrain Control Module (PCM) monitors the Low Speed Fuel Pump (LFP) primary circuit output from the PCM. The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit).

Possible symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
