DTC P018C: Fuel Pressure Sensor B Circuit Low

P018C - FUEL PRESSURE SENSOR B CIRCUIT LOW

Description:  The comprehensive component monitor (CCM) monitors the fuel pressure sensor circuit to the powertrain control module (PCM) for low voltage. The test fails if the voltage falls below a calibrated limit for a calibrated amount of time during testing.
Possible Causes: 
  • FLP signal short to SIGRTN or PWRGND
  • Damaged fuel pressure sensor
Diagnostic Aids:  A FLP PID value during ignition ON, engine OFF or ignition ON, engine running less than 0.3 volt indicates a concern is present.
