how to fix the P0301 code in my Ford Explorer Sixth Generation (2020-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative terminal of the battery.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 1:
  1. Unscrew the bolts holding the ignition coil in place.
  2. Gently pull the ignition coil out of the spark plug well.
• Remove the spark plug:
  1. Use a spark plug socket to unscrew and remove the spark plug.
• Inspect the spark plug for wear or damage (cracks, carbon buildup):
  1. If necessary, replace with a new spark plug that matches OEM specifications.
• Reinstall the new spark plug:
  1. Hand-tighten the spark plug using the socket, then torque to manufacturer specifications (typically around 13-15 lb-ft).
• Reinstall the ignition coil:
  1. Position the ignition coil over the spark plug and press it down until it clicks into place.
  2. Secure with the bolts removed earlier.

3. Inspect and Replace Ignition Coil (if necessary)

• If the ignition coil appears damaged, replace it:
  1. Disconnect the electrical connector from the ignition coil.
  2. Remove the coil as described above and replace it with a new coil.
• Reconnect the electrical connector and ensure it clicks into place.

4. Check Fuel Injector

• Remove the fuel injector for cylinder 1:
  1. Disconnect the fuel line and electrical connector to the injector.
  2. Unscrew the mounting screws and carefully extract the injector.
• Inspect the injector for clogs or damage:
  1. Clean or replace the injector if necessary.
• Reinstall the injector and reconnect all components.

5. Final Assembly

• Reconnect the negative battery terminal.
• Start the engine and allow it to reach operating temperature.
