how to fix the P0302 code on my Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather tools and parts needed.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before starting work.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug gap tool
• Remove the ignition coil from cylinder 2 by unscrewing the mounting bolts.
• Carefully pull out the ignition coil and disconnect the electrical connector.
• Remove the spark plug using a socket wrench.
• Inspect the old spark plug for wear; replace it with a new spark plug, ensuring it is properly gapped according to manufacturer specifications (typically 0.043 inches for Honda).
• Torque the new spark plug to 13 lb-ft (17.6 Nm).

3. Replace Ignition Coil (if necessary)

• If the ignition coil appears damaged or was not functioning correctly, replace it.
• Install the new ignition coil into cylinder 2.
• Reconnect the electrical connector and secure it with bolts.

4. Test Fuel Injector

• Tools Required: Noid light or multimeter
• Disconnect the fuel injector connector from cylinder 2.
• Connect a noid light to the injector connector to check for electrical signal during cranking.
• If no signal is present, inspect wiring and connectors for damage.
• If the injector is faulty, replace it with a new one.

5. Reassemble and Check

• Reinstall any components removed for access.
• Reconnect the negative battery terminal.
• Start the engine and ensure it runs smoothly.
