Pinpoint Test E: PC-A (Line Pressure) Solenoid

WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: This test should only be used if DTCs P0748, P0960, P0962 or P0963 are present.
NOTE: Refer to the TRANSMISSION VEHICLE HARNESS CONNECTOR  illustration preceding these pinpoint tests.
NOTE: Refer to the INTERNAL HARNESS CONNECTOR  illustration preceding these pinpoint tests.
  1. E1 CHECK VEHICLE HARNESS FOR CONTINUITY 
    • Key in OFF position.
    • Disconnect powertrain control module (PCM), inspect for damage or pushed out pins, corrosion, or loose wires.
    • Disconnect vehicle harness from transmission, inspect for damage or pushed out pins, corrosion, or loose wires.
    • Measure resistance between PCM pin 2, and the signal pin 10 at transmission harness connector.
    • Measure resistance between PCM pin 7 and the power pin 7 at the transmission harness connector.
    • Is each resistance less than 5.0 ohms? 
    • Yes  : GO to E2.
    • No  : REPAIR an open. RECONNECT all components. REPEAT Quick Test.
  2. E2 CHECK VEHICLE HARNESS FOR SHORTS TO POWER AND GROUND 
    • Measure resistance between PCM signal pin 2 and the power pin 7.
    • Measure resistance between PCM pin 2 and 22 and chassis ground.
    • Is each resistance greater than 10,000 ohms? 
    • Yes  : GO to E3.
    • No  : SERVICE short circuit. RECONNECT all components. REPEAT Quick Test.
  3. E3 CHECK THE TRANSMISSION INTERNAL HARNESS 
    • Drain the transmission fluid.
    • Remove the transmission fluid pan.
    • Disconnect: Affected Solenoid.
    • Measure the resistance between pin 10 transmission bulkhead side and pin 2 at the solenoid connector.
    • Measure the resistance between pins 7, 20 and 24 transmission bulkhead side and pin 1 at each associated solenoid connector.
    • Are the resistances less than 0.5 ohms? 
    • Yes  : GO to E4.
    • No  : INSTALL a new harness. RECONNECT all components. REPEAT Quick Test.
  4. E4 CHECK FOR A SHORT TO GROUND 
    • Measure the resistance between pins 10 harness side and ground.
    • Is the resistance greater than 10,000 ohms? 
    • Yes  : GO to E5.
    • No  : INSTALL a new harness. RECONNECT all components. REPEAT Quick Test.
  5. E5 CHECK THE SOLENOID RESISTANCE AT THE SOLENOID 
    NOTE: Early production transmissions will have a PCA solenoid with a resistance value of 4.1 - 4.7 ohms. Late production transmissions will have a resistance value of 5.08 - 5.80 ohms.
    • Measure the resistance between pins 1 and 2 at each solenoid.
    • Is the resistance for PCA solenoid (late production) between 5.08 - 5.80 ohms? 

      Is the resistance for PCA solenoid (early production) between 4.1 - 4.7 ohms? 

    • Yes  : GO to E6.
    • No  : INSTALL a new solenoid if not within specification. CLEAR the DTCs. TEST the system for normal operation.
  6. E6 CHECK THE SOLENOID FOR A SHORT TO GROUND 
    • Measure the resistance between pins 1 and 2 at each solenoid and ground.
    • If the resistance greater than 10,000 ohms? 
    • Yes  : INSTALL a new PCM. If the condition persists, REFER to DIAGNOSIS BY SYMPTOM  for diagnosis of pressure concerns. CLEAR the DTCs. TEST the system for normal operation.
    • No  : INSTALL a new solenoid. CLEAR the DTCs. TEST the system for normal operation.
