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

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Compression tester
• Multimeter
• Screwdrivers
• Safety glasses and gloves

2. Inspect and Replace Spark Plug

1. Remove the ignition coil from cylinder 1 by unscrewing the retaining bolts and disconnecting the electrical connector.
2. Remove the spark plug using a spark plug socket and extension.
3. Inspect the spark plug for wear, carbon deposits, or damage. Replace it if necessary.
4. Gap the new spark plug to the manufacturer’s specifications and install it.
5. Reinstall the ignition coil and reconnect the electrical connector.

3. Test and Replace Ignition Coil (if necessary)

1. Use a multimeter to test the resistance of the ignition coil for cylinder 1, comparing it with manufacturer specifications.
2. If the ignition coil is faulty, remove the old coil and install the new one, ensuring it is seated properly.
3. Reconnect the electrical connector.

4. Test Fuel Injector

1. Use a multimeter to check the resistance of the fuel injector for cylinder 1.
2. If the injector shows abnormal readings, disconnect it and replace it with a new one.
3. Reconnect the fuel line and electrical connector once the new injector is installed.

5. Perform Compression Test

1. Remove the spark plug from cylinder 1.
2. Insert the compression tester into the spark plug hole.
3. Crank the engine and record the compression reading.
4. If the reading is below specifications, further investigation into valve seals or piston rings may be necessary.
