PCM P04BA:00 Fuel Fill Door Position Sensor/Switch Circuit High: No Sub Type Information Sets when the PCM detects the fuel filler door did not open when the PCM activated the fuel filler door release relay. An open circuit to the fuel filler door ajar switch can cause this DTC to set.

Possible Sources

  • Wiring, terminals or connectors
  • Fuel filler door ajar switch (part of the fuel filler door housing)
  • PCM
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
AK1 CHECK FOR MECHANICAL DAMAGE
  • Ignition OFF.
  • Inspect fuel filler door for damage near the ajar switch.

Is any damage present?
Yes REPAIR or INSTALL a new fuel filler door housing as necessary.
No GO to AK2

AK2 CHECK THE PCM (POWERTRAIN CONTROL MODULE) THE CUSTOMER IS REQUESTING OR HAS RECENTLY REQUESTED TO OPEN OR UNLOCK THE FUEL FILL DOOR (FUELDR_REQ) PID (PARAMETER IDENTIFICATION)
  • Ignition ON.

  • Access the  PCM  and monitor the  FUELDR_REQ (none)  PID

  • Monitor the PCM FUELDR_REQ PID while pressing and releasing the fuel filler door release button.

Does the PID momentarily indicate Yes?
Yes GO to AK3
No GO to Pinpoint Test AI

AK3 CHECK THE FUEL FILLER DOOR RELEASE USING THE PCM (POWERTRAIN CONTROL MODULE) FUEL FILL DOOR UNLOCK CONTROL OUTPUT IS COMMANDED TO ENABLE STATE (FUELDR_UNLOCK) PID (PARAMETER IDENTIFICATION)
  • Verify the fuel filler door is fully closed.

  • Access the  PCM  and control the  FUELDR_UNLOCK (none)  PID

  • Command the PCM FUELDR_UNLOCK PID On.

Does the fuel filler door latch release?
Yes GO to AK4
No GO to Pinpoint Test AI

AK4 CHECK THE PCM (POWERTRAIN CONTROL MODULE) THE FUEL FILL DOOR POSITION SENSOR/SWITCH CIRCUIT INPUT (FUELDR_POS_SW) PID (PARAMETER IDENTIFICATION)
  • Close the fuel filler door.

  • Access the  PCM  and monitor the  FUELDR_POS_SW (none)  PID

  • Monitor the PCM FUELDR_POS_SW PID.

  • Access the  PCM  and control the  FUELDR_UNLOCK (none)  PID

  • Command the PCM FUELDR_UNLOCK PIDOn.
  • Verify the fuel filler door latch released.

Does the PID indicate Closed with the fuel filler door closed and Open after the fuel filler door latch is released?
Yes The system is operating correctly. REFER to Normal Operation and Fault Conditions at the beginning of this Pinpoint Test.
No GO to AK5

AK5 CHECK THE FUEL FILLER DOOR AJAR CIRCUITS FOR A SHORT TO VOLTAGE

NOTE: The fuel filler door electrical connectors can be accessed through an opening in the left side sheet metal inside luggage compartment area.

  • Ignition OFF.
  • Disconnect Fuel Filler Door Release Solenoid C4089 .
  • Disconnect PCM C1551B .
  • Ignition ON.
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C4089-2   Ground
      C4089-3   Ground

Is any voltage present?
Yes REPAIR the circuit in question.
No GO to AK6

AK6 CHECK THE FUEL FILLER DOOR AJAR CIRCUITS FOR A SHORT TO GROUND
  • Ignition OFF.
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C4089-2   Ground
      C4089-3   Ground

Are the resistances greater than 10,000 ohms?
Yes GO to AK7
No REPAIR the circuit in question.

AK7 CHECK THE FUEL FILLER DOOR AJAR CIRCUITS FOR AN OPEN
  • Measure:
    Click to display connectors
    Positive Lead Measurement / Action Negative Lead
      C4089-2   C1551B-88
      C4089-3   C1551B-50

Are the resistances less than 3 ohms?
Yes INSTALL a new fuel filler door housing. CLEAR the Diagnostic Trouble Codes (DTCs) and repeat the self-test. If the concern is still present, GO to AK8
No REPAIR the circuit in question.

AK8 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION
  • Disconnect and inspect all the PCM connectors.
  • Repair:
    • corrosion (install new connectors 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 and 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern,
   Click here to access Guided Routine (PCM). Internet Explorer version 11 or greater is required to perform this Pinpoint Test.
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.
