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

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Remove the engine cover if necessary.
• Locate cylinder 1 spark plug (usually at the front of the engine).
• Use a socket wrench to remove the spark plug.
• Inspect the spark plug for signs of wear, carbon build-up, or damage.
• If necessary, replace with a new spark plug (specification: [Manufacturer’s recommended part number]).
• Torque the new spark plug to the manufacturer’s specifications (typically around 20-30 Nm).

3. Test and Replace Ignition Coil

• Disconnect the ignition coil connector.
• Remove the ignition coil from cylinder 1 using a socket wrench.
• Test the ignition coil with a multimeter (check for primary and secondary resistance).
• If faulty, replace with a new ignition coil (specification: [Manufacturer’s recommended part number]).
• Reinstall the ignition coil and reconnect the electrical connector.

4. Inspect and Test Fuel Injector

• Locate the fuel injector for cylinder 1.
• Disconnect the electrical connector and fuel line (use caution with fuel).
• Test the injector with a multimeter for resistance and continuity.
• If the injector is not functioning properly, replace it with a new fuel injector (specification: [Manufacturer’s recommended part number]).
• Reconnect the fuel line and electrical connector.

5. Compression Test

• Remove the spark plug from cylinder 1 again.
• Insert a 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 [insert specific compression range]).
• If compression is low, further investigation into engine internals may be necessary.
