what does it mean if my Toyota Camry Eighth Generation (2018-present) has a P0302 code

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Disconnect the battery by removing the negative terminal to ensure safety.
• Allow the engine to cool down if it has been running.

2. Inspect and Replace Spark Plug

• Remove the engine cover if applicable.
• Locate cylinder 2 (usually the second cylinder from the front).
• Remove the spark plug wire or ignition coil from cylinder 2.
• Use a socket set to remove the spark plug from cylinder 2.
• Inspect the spark plug for wear or deposits. If damaged, replace with a new spark plug (refer to manufacturer specifications for gap size).
• Reinstall the spark plug and reconnect the ignition coil or spark plug wire.

3. Check and Replace Ignition Coil

• Disconnect the ignition coil connector for cylinder 2.
• Remove the ignition coil using a socket set.
• Test the ignition coil with a multimeter to ensure it meets manufacturer specifications.
• If faulty, replace with a new ignition coil and reconnect the connector.

4. Inspect Fuel Injector

• Locate the fuel injector for cylinder 2.
• Disconnect the fuel injector connector.
• Use a multimeter to test the injector's resistance. If it does not meet specifications, replace the fuel injector.
• Reinstall the injector and reconnect the connector.

5. Perform Compression Test (if necessary)

• If misfire persists, conduct a compression test on cylinder 2.
• Remove the spark plug and install the compression gauge.
• Crank the engine and record the reading. Compare it to specifications.
• If compression is low, further investigation into engine internals may be required.
