how to fix the P0301 code in my Skoda Octavia NFL (2020-Present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Spark Plug

1. Remove the engine cover if applicable.
2. Use a socket wrench to remove the spark plug from cylinder 1.
3. Inspect the spark plug for signs of wear, such as fouling or damage.
4. Replace with a new spark plug that matches OEM specifications (usually a NGK or Bosch brand).
5. Torque the new spark plug to the manufacturer’s specified value (typically around 25 Nm).

3. Check and Replace Ignition Coil

1. Disconnect the electrical connector from the ignition coil on cylinder 1.
2. Remove the ignition coil using a socket set.
3. Inspect the coil for cracks or signs of damage.
4. Replace with a new ignition coil if necessary (ensure it matches OEM specifications).
5. Reinstall the ignition coil and reconnect the electrical connector.

4. Inspect Fuel Injector

1. Locate the fuel rail and injector for cylinder 1.
2. Disconnect the electrical connector from the fuel injector.
3. Remove the injector using a wrench or socket.
4. Inspect for clogs or damage; clean or replace as necessary.
5. Reinstall the injector and reconnect the electrical connector.

5. Check Compression

1. Remove the spark plug from cylinder 1.
2. Insert a compression tester into the spark plug hole.
3. Crank the engine a few times to get a reading.
4. Compare the reading against the manufacturer’s specifications (typically around 150-200 psi).
5. If compression is low, further investigation into valve or piston issues is needed.
