why does my Ford F-150 Fourteenth Generation (2021-present) keep throwing P0301 code?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.
• Allow the engine to cool before proceeding to avoid burns.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 1 using a socket set.
• Inspect the spark plug for wear or fouling; replace if necessary.
• Install a new spark plug (use OEM specifications) and torque to the manufacturer’s specification (typically around 13-15 lb-ft).

3. Check and Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil by using a multimeter to check resistance.
• If the coil is faulty, remove the old ignition coil and install a new one.
• Ensure that all connections are secure before reconnecting the battery.

4. Inspect and Replace Fuel Injector

• If the ignition system is functioning correctly, check the fuel injector.
• Remove the fuel injector connector and inspect for damage.
• If the injector is faulty, remove the old injector and install a new one, ensuring to lubricate the O-rings with clean engine oil before installation.

5. Conduct a Compression Test

• If the issue persists, perform a compression test.
• Remove the spark plug and use a compression gauge to check the pressure in cylinder 1.
• If the compression is low, inspect for potential internal engine damage.
