how to solve the P0302 code in my Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface, the engine is cool, and the battery is disconnected.

2. Inspect and Replace Spark Plug

• Sub-steps:
  1. Remove the ignition coil from cylinder 2 by unbolting it and disconnecting the electrical connector.
  2. Remove the spark plug using a spark plug socket and ratchet.
  3. Inspect the spark plug for wear or fouling; replace if necessary with a spark plug that meets OEM specifications (typically Motorcraft SP-546).
  4. Gap the new spark plug to the manufacturer’s specification (usually 0.052-0.056 inches).
  5. Install the new spark plug and torque it to the manufacturer's specification (usually around 12-15 lb-ft).
  6. Reinstall the ignition coil and reconnect the electrical connector.

3. Inspect and Replace Ignition Coil

• Sub-steps:
  1. If the spark plug is in good condition, test the ignition coil by using a multimeter to check resistance.
  2. If out of spec, replace the ignition coil with an OEM or equivalent part.
  3. Reinstall the new ignition coil, ensuring proper seating and connection.

4. Inspect and Replace Fuel Injector

• Sub-steps:
  1. Disconnect the electrical connector and fuel line from the fuel injector for cylinder 2.
  2. Remove the fuel injector from the rail by gently twisting and pulling it out.
  3. Clean the injector port if necessary and install a new injector that meets OEM specifications.
  4. Reinstall the fuel injector and reconnect the fuel line and electrical connector.

5. Reassemble and Clear Codes

• Sub-steps:
  1. Reconnect the battery.
  2. Start the engine and allow it to reach normal operating temperature.
  3. Use an OBD-II scanner to clear the P0302 code.
