my Honda Accord's check engine light is on and I'm getting P0302 code what does it mean

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to avoid electrical shorts.

2. Inspect Spark Plug and Ignition Coil

• Tools Required: Socket set, torque wrench
• Remove the engine cover if applicable.
• Disconnect the electrical connector from the ignition coil of cylinder 2.
• Remove the ignition coil using a socket wrench.
• Check the spark plug for wear, carbon buildup, or damage; replace if necessary.
• Inspect the ignition coil for cracks or corrosion; replace if necessary.

3. Check Fuel Injector

• Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
• Use a multimeter to check the resistance of the fuel injector for cylinder 2; compare to manufacturer specifications.
• If faulty, remove the fuel injector, clean or replace it as necessary.

4. Perform Compression Test

• Tools Required: Compression gauge
• Remove the spark plug from cylinder 2.
• Insert the compression gauge into the spark plug hole and crank the engine.
• Record the compression reading; compare it to the specifications for your Honda Accord.
• If compression is low, further inspection of the internal engine components may be necessary.

5. Inspect Vacuum Lines

• Visually check all vacuum lines connected to the intake manifold for cracks or disconnections.
• Use a smoke machine or soapy water to detect leaks if necessary.
• Replace any damaged vacuum lines.
