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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on the electrical systems.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 1.
• Unscrew the spark plug using a spark plug socket.
• Inspect the spark plug for wear, carbon buildup, or damage.
• If necessary, replace with a new spark plug (ensure correct heat range and gap).
• Reinstall the spark plug and the ignition coil, ensuring they are secure.

3. Test and Replace Ignition Coil (if needed)

• Use a multimeter to test the resistance of the ignition coil.
• If the resistance is outside manufacturer specifications, replace the ignition coil.
• Install the new ignition coil and reconnect all electrical connections.

4. Inspect and Clean Fuel Injector

• Remove the fuel injector from cylinder 1.
• Inspect for clogs or debris.
• If dirty, clean using an appropriate fuel injector cleaner or replace if necessary.
• Reinstall the fuel injector ensuring it is properly seated and connected.

5. Perform Compression Test

• Insert the compression tester into the spark plug hole of cylinder 1.
• Crank the engine and record the compression reading.
• Compare the reading to manufacturer specifications; if low, further investigate for mechanical issues (e.g., valve or piston damage).
