how to fix P0302 code on my Ford F-150 Fourteenth Generation (2021-present)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is on a flat surface and the engine is cool.
• Disconnect the battery to ensure safety.

2. Replace Spark Plug and Ignition Coil (if faulty)

1. Remove Engine Cover (if applicable)

   • Use a socket set to remove bolts securing the engine cover.
   • Carefully lift off the cover and set it aside.

2. Access Cylinder 2 Components

   • Locate the ignition coil and spark plug for cylinder 2 (refer to service manual for exact location).

3. Remove Ignition Coil

   • Unplug the electrical connector from the ignition coil.
   • Remove the bolt securing the ignition coil using a socket wrench.
   • Gently pull the ignition coil out of the cylinder head.

4. Replace Spark Plug

   • Use a spark plug socket to remove the spark plug from cylinder 2.
   • Inspect the old spark plug for signs of damage or wear.
   • Install a new spark plug (check gap specifications in the owner's manual) and torque to the manufacturer’s specification (typically around 13-15 lb-ft).

5. Install New Ignition Coil

   • Insert the new ignition coil into the cylinder head and secure it with the bolt.
   • Reconnect the electrical connector.

3. Check Fuel Injector

1. Inspect and Replace Fuel Injector (if necessary)
   • Remove the fuel rail (if the injector is not externally accessible).
   • Disconnect the fuel line and electrical connector from the injector.
   • Remove the faulty fuel injector and replace it with a new one.
   • Reassemble the fuel rail and ensure all connections are secure.

4. Reassemble and Reconnect

• Reattach any components removed, including the engine cover.
• Reconnect the battery terminals (positive first, then negative).
