Test Procedure

2009 Ford Fusion SEL, 3.0 1, FWDSECTION Test Procedure
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. TM1 DIAGNOSTIC TROUBLE CODES (DTCS) P0A2F AND P0A3C: CHECK FOR SELF-TEST DTCS 

    Are DTCs P0A2F or P0A3C present during PCM or transaxle control module (TCM) self-test? 

    Yes No
    For DTC P0A2F, GO to  TM6.
    For DTC P0A3C, GO to  TM2.
    Unable to duplicate or identify the concern at this time.
    RETURN to SYMPTOM CHARTS for further direction.
  2. TM2 DTC P0A3C: CHECK FOR THE PRESENCE OF PCM DTCS P0A00, P0A02, P0A03, P0A7C 

    Are any of the above listed DTCs present? 

    Yes No
    DISREGARD the current diagnostic trouble code (DTC) at this time. DIAGNOSE the next DTC. GO to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS . GO to  TM3.
  3. TM3 VISUAL INSPECTION OF THE MOTOR ELECTRONICS COOLING SYSTEM 
    NOTE: Repair any MECS pump DTCs before proceeding.
    • Visually inspect the motor electronics cooling system for leaks, pinched hoses, restricted radiator air flow, correct coolant level, coolant flow at the degas reservoir, fan operation, and loose electrical connections.

    Is the motor electronics cooling system OK? 

    Yes No
    GO to  TM4. REPAIR as necessary.
    CLEAR the DTCs. REPEAT the self-test.
  4. TM4 CHECK THE TCM MOTOR ELECTRONICS COOLANT TEMPERATURE (MECT) PID 
    NOTE: Access the MECT PID from the freeze frame PID menu.

    Refer to the scan tool instruction manual for freeze frame PID menu.

    • Access the TCM and monitor the MECT PID.

    Is the temperature less than 60°C (140°F)? 

    Yes No
    INSTALL a new transaxle assembly. REFER to the AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 . GO to  TM5.
  5. TM5 CHECK THE MCLTEMP WHILE RECREATING THE SYMPTOM 
    NOTE: The vehicle may need to be driven in order to recreate the original conditions that set the DTC or caused the symptom.
    • Access the freeze frame data (if available) and record the DTC conditions.
    • Clear the TCM DTCs.
    • Obtain information from the customer information worksheet or any other available data from the customer.
    • Recreate the symptom using freeze frame and customer information.
    • Access the TCM and monitor the MCLTEMP PID.

    Is the temperature less than 220°C (428°F) when the symptom occurs? 

    Yes No
    Unable to duplicate or identify the concern at this time.
    RETURN to SYMPTOM CHARTS for further direction.
    INSTALL a new transaxle assembly. REFER to the AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .
  6. TM6 DTC P0A2F: CHECK THE AUTOMATIC TRANSAXLE FLUID LEVEL 
    NOTE: A low automatic transaxle fluid level may cause an traction motor over temperature condition.

    Is the transaxle fluid level correct? 

    Yes No
    GO to  TM7. ADD the necessary fluid to obtain the correct fluid level.
    REFER to the AUTOMATIC TRANSAXLE/TRANSMISSION - 6F35 .
    GO to  TM8.
  7. TM7 VISUAL INSPECTION OF THE MOTOR ELECTRONICS COOLING SYSTEM 
    NOTE: Repair any MECS pump DTCs before proceeding.
    • Visually inspect the motor electronics cooling system for leaks, pinched hoses, restricted radiator air flow, correct coolant level, coolant flow at the degas reservoir, fan operation, and loose electrical connections.

    Is the motor electronics cooling system OK? 

    Yes No
    GO to  TM8. REFER to the TRANSAXLE/TRANSMISSION COOLING - HYBRID -- ESCAPE & MARINER to diagnose motor electronics cooling system concerns.
  8. TM8 CHECK THE MCLTEMP WHILE RECREATING THE SYMPTOM 
    NOTE: The vehicle may need to be driven in order to recreate the original conditions that set the DTC or caused the symptom.
    • Access the freeze frame data (if available) and record the DTC conditions.
    • Clear the TCM DTCs.
    • Obtain information from the customer information worksheet or any other available data from the customer.
    • Recreate the symptom using freeze frame and customer information.
    • Access the TCM and monitor the MCLTEMP PID.
    • Record the MCLTEMP PID reading when the symptom occurs.

    Could the symptom be recreated? 

    Yes No
    GO to  TM9. Unable to duplicate or identify the concern at this time.
    RETURN to SYMPTOM CHARTS for further direction.
  9. TM9 CHECK THE MCLTEMP WHILE RECREATING THE SYMPTOM 

    Is the temperature less than 220°C (428°F) when the symptom occurs? 

    Yes No
    RETURN to SYMPTOM CHARTS for further direction. INSTALL a new transaxle assembly.

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.
