what does code P0302 mean for my Honda Accord 9th Generation (2013-2017)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the negative battery terminal to avoid electrical shock.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2.
  • Tools: Socket set, ratchet.
• Remove the spark plug using a spark plug socket.
  • Check for carbon buildup or electrode wear.
• Replace with a new spark plug that meets OEM specifications.
  • Torque the new spark plug to the manufacturer's specification (typically around 13-15 lb-ft).

3. Check and Replace Ignition Coil

• Test the ignition coil for proper resistance using a multimeter.
  • If faulty, remove the ignition coil.
  • Tools: Socket set, multimeter.
• Install a new ignition coil.
  • Reconnect the wiring harness securely.

4. Inspect and Clean Fuel Injector

• Disconnect the fuel injector connector and fuel line (ensure residual pressure is relieved).
  • Tools: Fuel line disconnect tool, safety glasses.
• Remove the fuel injector from cylinder 2.
• Clean the injector using a fuel injector cleaner or replace it if necessary.
• Reinstall the cleaned or new injector and reconnect the fuel line.

5. Perform Compression Test

• Insert a compression gauge into the spark plug hole of cylinder 2.
• Crank the engine and record the compression reading.
• Compare the reading to specifications (typically 180-220 psi). If low, further mechanical inspection is needed.
