my Honda Accord 10th Generation (2018-2022) has a P0301 code what does it mean

Solution

1. Preparation

• Gather tools and necessary parts.
• Disconnect the negative battery terminal to avoid electrical shorts.
• Allow the engine to cool down before beginning work.

2. Inspect and Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket, dielectric grease.
• Remove the ignition coil from cylinder 1 by unscrewing the bolts and disconnecting the electrical connector.
• Remove the spark plug using the spark plug socket.
• Inspect the spark plug for damage and excessive carbon buildup; replace if necessary.
• Apply a small amount of dielectric grease to the new spark plug threads.
• Install the new spark plug and torque it to the manufacturer's specifications (typically around 13 lb-ft).

3. Check and Replace Ignition Coil

• Inspect the ignition coil for cracks or signs of wear.
• If necessary, replace the ignition coil for cylinder 1 by disconnecting the electrical connector and removing the mounting bolts.
• Install the new ignition coil and reconnect the electrical connector.

4. Inspect Fuel Injector

• Tools Required: Fuel pressure gauge, injector removal tool.
• Disconnect the fuel injector electrical connector and remove any retaining clips.
• Using the injector removal tool, carefully remove the fuel injector from cylinder 1.
• Inspect the injector for clogs or leaks; replace if necessary.
• Reinstall the injector and ensure it is seated properly.

5. Compression Test

• Tools Required: Compression gauge.
• Remove the spark plug from cylinder 1 and thread in the compression gauge.
• Crank the engine to obtain a compression reading.
• Compare the reading to the manufacturer's specifications; if it is low, further investigation is needed for internal engine issues.
