  6. G6 CHECK THE GENERATOR CURRENT SENSOR FEEDBACK CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect PCM C175B  (1.6L EcoBoost).
    • Disconnect PCM C1381B  (2.0L EcoBoost).
    • Disconnect PCM C1551B  (2.5L Duratec).

      Positive Lead Measurement/Action Negative Lead
      C1645-3  VOLTAGE Ground

    Is any voltage present? 

    • Yes  : REPAIR the circuit.
    • No  : GO to G7 
  7. G7 CHECK THE GENERATOR CURRENT SENSOR FEEDBACK CIRCUIT FOR A SHORT TO THE SIGNAL RETURN OR VOLTAGE REFERENCE CIRCUIT 
    • Ignition OFF.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C1645-3  OHM C1645-1 
      C1645-3  OHM C1645-2 

    Are the resistances greater than 10, 000 ohms? 

    • Yes  : GO to G8 
    • No  : REPAIR the affected circuit.
  8. G8 CHECK THE GENERATOR CURRENT SENSOR FEEDBACK CIRCUIT FOR AN OPEN 
    • For the 1.6L EcoBoost with automatic transmission, measure:
      Positive Lead Measurement/Action Negative Lead

    • For the 2.5L Duratec, measure:
      Positive Lead Measurement/Action Negative Lead
      C1551B-33  OHM C1645-3 

    Is the resistance less than 3 ohms? 

    • Yes  : GO to G9 
    • No  : REPAIR the circuit.
  9. G9 CHECK THE GENERATOR CURRENT SENSOR CONNECTION 
    • Ignition OFF.
    • Disconnect Generator current sensor C1645  .
    • Inspect the generator current sensor connector for the following:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Using a diagnostic scan tool, perform the PCM  self-test

    Did the DTC return? 

    • Yes  : REPAIR as necessary or INSTALL a new generator current sensor.

      REFER to: GENERATOR CURRENT SENSOR .

      CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If the DTC  returns, GO to G10 

    • No  : The system is operating correctly at this time. The concern may have been caused by an intermittently loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
  10. G10 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION 
    • Ignition OFF.
    • Disconnect and inspect all PCM  connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the PCM  connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    • Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW the TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new PCM  . For 1.6L EcoBoost, REFER to: POWERTRAIN CONTROL MODULE (PCM) - 1.6L EcoBoost (132kW/180PS) - Sigma .

      For 2.0L EcoBoost, REFER to: POWERTRAIN CONTROL MODULE (PCM) - 2.0L EcoBoost (184kW/250PS) - MI4 .

      For 2.5L Duratec REFER to: POWERTRAIN CONTROL MODULE (PCM) - 2.5L Duratec (125kW/170PS) .

      CLEAR all Diagnostic Trouble Codes (DTCs) in all modules.

    • No  : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
