how to fix P0301 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 parked on a level surface and the ignition is turned off.
• Disconnect the battery to ensure safety.

2. Inspect and Replace Spark Plug and Ignition Coil

• Tools Required: Socket set, torque wrench, spark plug socket, dielectric grease.
• Remove the engine cover if applicable.
• Disconnect the ignition coil connector for cylinder 1.
• Remove the ignition coil by unscrewing the retaining bolt.
• Remove the spark plug using a spark plug socket. Inspect for wear or carbon buildup.
• Replace the spark plug with a new one, torquing it to the manufacturer's specification (typically around 13-15 lb-ft).
• Apply dielectric grease to the ignition coil boot and reinstall the ignition coil, securing it with the retaining bolt.
• Reconnect the ignition coil connector.

3. Test and Replace Fuel Injector (if necessary)

• Tools Required: Fuel injector puller (if applicable), O-ring lubricant.
• Disconnect the fuel injector connector for cylinder 1.
• Remove the fuel rail bolts and gently pull the rail away to access the injector.
• Remove the fuel injector and inspect it for clogs or damage.
• If faulty, replace the fuel injector and lubricate the O-rings before installation.
• Reassemble the fuel rail, ensuring all connections are secure.

4. Check for Vacuum Leaks

• Visually inspect hoses and connections around the intake for signs of wear or disconnection.
• If applicable, use a smoke tester to find any leaks in the intake manifold or vacuum lines.
