how can I fix the P0302 code in my Honda Accord 8th Generation (2008-2012)

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery cable.
• Ensure the engine is cool before starting work.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench.
• Remove the ignition coil from cylinder 2 by unbolting it and disconnecting the electrical connector.
• Remove the spark plug from cylinder 2 using a spark plug socket.
• Inspect the old spark plug; replace if worn or damaged.
• Install the new spark plug with the proper gap and torque it to the manufacturer’s specifications (usually around 13-16 lb-ft).
• Reinstall the ignition coil and reconnect the electrical connector.

3. Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil with a multimeter to ensure it is functioning correctly.
• If faulty, remove the ignition coil from cylinder 2.
• Install the new ignition coil and reconnect the electrical connector.

4. Inspect and Clean Fuel Injector

• If the ignition coil and spark plug are not the issue, remove the fuel injector from cylinder 2.
• Clean the injector using an appropriate fuel injector cleaner or replace it if necessary.
• Reinstall the injector and ensure it is securely connected.

5. Reassemble and Test

• Reconnect the negative battery cable.
• Start the engine and allow it to reach operating temperature.
• Check for any new error codes or if the check engine light reappears.
