how to fix P0700 code in Ford F-150 12th Generation (2009-2014)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Transmission Fluid

• Remove the transmission dipstick (if applicable) and check fluid level.
• If low, add the recommended transmission fluid (Ford MERCON LV).
• If the fluid is dirty or burnt, perform a transmission fluid and filter change.

3. Inspect Wiring and Connectors

• Locate the TCM and inspect the wiring harness for frayed wires or corrosion.
• Disconnect the TCM connector and clean the terminals with electronic cleaner.
• Reconnect the wiring and ensure a tight fit.

4. Test Transmission Control Module (TCM)

• Use a multimeter to check the voltage at the TCM connector.
• Compare readings with the specifications in the service manual.
• If readings are out of range, replace the TCM.

5. Replace Transmission Control Solenoids

• Remove the transmission pan using a socket set; drain the fluid.
• Replace defective transmission control solenoids as needed.
• Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (typically 12-15 ft-lbs).

6. Clear Codes and Test Drive

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code.
• Perform a test drive to ensure that the issue is resolved.
