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

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shocks.
• Allow the engine to cool down if it has been running.

2. Replace Spark Plug

• Tools Required: Socket set, spark plug socket, torque wrench.
• Remove the engine cover if applicable.
• Locate cylinder 1 spark plug (refer to the vehicle manual for position).
• Use the spark plug socket to unscrew and remove the old spark plug.
• Inspect the gap on the new spark plug and adjust to the manufacturer specifications.
• Install the new spark plug and torque it to the specified value (typically 15-20 Nm).

3. Inspect and Replace Ignition Coil

• Tools Required: Socket set, multimeter (optional).
• Disconnect the electrical connector from the ignition coil on cylinder 1.
• Remove the ignition coil by unscrewing the mounting bolts.
• Replace with a new ignition coil if the old one is faulty (if testing confirms failure).
• Reconnect the electrical connector and ensure a secure fit.

4. Test Fuel Injector

• Tools Required: Noid light, multimeter.
• Disconnect the fuel injector connector on cylinder 1.
• Connect a noid light to check for injector pulse when cranking the engine.
• If no signal is detected, inspect wiring and connectors for damage.
• Replace the fuel injector if it fails the test.

5. Compression Test

• Tools Required: Compression tester.
• Remove the spark plug from cylinder 1 and install the compression tester.
• Crank the engine and record the compression reading.
• Compare the reading to the manufacturer specifications; if low, further investigation is needed for internal engine issues.
