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

Solution

1. Preparation

• Gather tools and parts.
• Ensure the engine is cool and the vehicle is parked on a level surface.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Spark Plug

1. Remove the ignition coil from cylinder 1 by unbolting it and disconnecting the electrical connector.
2. Use a spark plug socket to remove the old spark plug from cylinder 1.
3. Inspect the old spark plug and ensure the new spark plug is gapped correctly (typically 0.028-0.032 inches for Ford engines).
4. Install the new spark plug by hand to avoid cross-threading, then tighten it to manufacturer specifications (usually around 13-15 lb-ft).

3. Replace Ignition Coil

1. If the ignition coil is defective, install the new ignition coil onto the spark plug, ensuring it is seated correctly.
2. Reconnect the electrical connector to the ignition coil.
3. Secure the ignition coil with the appropriate bolts.

4. Inspect and Replace Fuel Injector (if necessary)

1. Disconnect the fuel injector connector and remove any retaining clips.
2. Carefully extract the fuel injector from the fuel rail.
3. Install the new fuel injector with new O-rings to prevent leaks.
4. Reconnect the fuel injector connector.

5. Reconnect Battery and Test

1. Reconnect the negative battery terminal.
2. Start the engine and allow it to idle, monitoring for any irregularities.
