how to fix the P0301 code on my Honda Pilot Third Generation (2016-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the engine is cool and disconnect the negative battery terminal to prevent electrical shock.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil from cylinder 1 by unscrewing the mounting bolts and disconnecting the electrical connector.
• Use a spark plug socket to remove the old spark plug from cylinder 1.
• Inspect the old spark plug for signs of wear or damage.
• Install the new spark plug by hand to avoid cross-threading, then tighten it to the manufacturer’s specified torque (typically around 13 lb-ft).

3. Replace Ignition Coil (if necessary)

• Tools Required: Socket set, torque wrench.
• If the ignition coil is faulty, remove the old coil from cylinder 1 and replace it with a new one.
• Ensure the new coil is securely mounted and reconnect the electrical connector.

4. Inspect Fuel Injector (if necessary)

• Tools Required: Fuel injector cleaning kit or replacement injector.
• If the fuel injector is suspected to be clogged, use a cleaning kit to clean it or replace it if necessary.
• Reinstall the fuel injector, ensuring proper sealing and connection.

5. Reconnect Battery

• Reconnect the negative battery terminal after all components have been checked or replaced.
