what does it mean if my Toyota Camry has a code P0302?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shock.
• Allow the engine to cool before starting work.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2.
• Use a spark plug socket to remove the spark plug.
• Inspect the spark plug for fouling or damage.
• Replace with a new spark plug if necessary (usually OEM recommended).
• Reinstall the spark plug and torque to the manufacturer's specification (typically around 13 lb-ft).

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, test the ignition coil.
• Remove the ignition coil from cylinder 2.
• Test the coil with a multimeter, checking for proper resistance.
• Replace the ignition coil if it is faulty.
• Reinstall the ignition coil and ensure it is secured properly.

4. Check Fuel Injector

• Disconnect the fuel injector connector for cylinder 2.
• Test the injector for electrical continuity using a multimeter.
• If the injector is faulty, remove and replace it with a new one.
• Reconnect the fuel injector and ensure the connector is secure.

5. Verify Compression

• Remove the spark plug for cylinder 2 and install a compression gauge.
• Crank the engine and take a compression reading.
• If compression is below the manufacturer's specification, further investigation into internal engine issues may be needed.
