how to fix P0301 code on Ford F-150 13th Generation (2015-2020)?

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the battery to prevent electrical shorts.
• Allow the engine to cool down.

2. Replace Spark Plug and Ignition Coil

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the engine cover if applicable.
• Disconnect the electrical connector from the ignition coil on cylinder 1.
• Remove the ignition coil by unscrewing it from the cylinder head.
• Remove the spark plug using a spark plug socket.
• Inspect the old spark plug for signs of wear or damage.
• Install the new spark plug and torque it to the manufacturer’s specification (typically around 13-15 lb-ft).
• Reinstall the ignition coil and reconnect the electrical connector.

3. Test Fuel Injector

• Tools Required: Fuel pressure gauge or noid light.
• Disconnect the fuel injector connector for cylinder 1.
• Use a noid light to check if the injector is receiving the correct signal from the ECU.
• If the signal is good, connect a fuel pressure gauge to the fuel rail to verify fuel pressure meets specifications (typically around 30-40 psi).
• If the injector is faulty, replace it with a new one and reconnect the fuel line.

4. Verify Compression (if necessary)

• Tools Required: Compression tester.
• Remove the spark plug from cylinder 1.
• Insert the compression tester into the spark plug hole.
• Crank the engine and record the compression reading.
• Compare the reading to the manufacturer’s specifications (usually around 120-160 psi).
• If the compression is low, it may indicate an internal engine issue that requires further diagnosis.
