what does it mean if my Honda Accord has a P0302 code

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety during the repair process.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2.
• Take out the spark plug using a socket and ratchet.
• Inspect the spark plug for any signs of fouling, wear, or damage; replace if necessary.
• Torque the new spark plug to the manufacturer’s specifications (typically around 13 lb-ft for Honda).

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil for cylinder 2 using a multimeter.
• If faulty, remove the ignition coil and replace it with a new one.
• Reconnect the ignition coil ensuring it is seated properly.

4. Check and Clean Fuel Injector

• Remove the fuel injector from cylinder 2.
• Inspect the injector for clogs or damage; use a fuel injector cleaner if necessary.
• Reinstall the fuel injector ensuring it is secure and properly connected.

5. Compression Test

• If misfire persists, perform a compression test on cylinder 2.
• Compare the results with the manufacturer's specifications; if low, further engine diagnosis may be required.
