what does it mean when my Toyota Camry XV40 has P0302 code?

Solution

1. Preparation

• Gather tools and parts needed for repairs.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Spark Plug

• Remove the spark plug from Cylinder 2 using a socket set.
• Inspect the spark plug for fouling or wear; replace if necessary.
• Torque the new spark plug to the manufacturer's specifications (typically around 13-15 ft-lbs).

3. Check and Replace Ignition Coil

• Disconnect the ignition coil connector for Cylinder 2.
• Remove the ignition coil using a socket set.
• Inspect for cracks or damage; replace if faulty.
• Reinstall the new ignition coil and reconnect the connector.

4. Fuel Injector Testing

• Disconnect the fuel injector connector for Cylinder 2.
• Use a multimeter to check the resistance; it should be within the manufacturer's specified range.
• If the injector is faulty, remove it and replace it with a new one while following the manufacturer's instructions.

5. Compression Test

• Remove the spark plug from Cylinder 2.
• Insert a compression tester into the spark plug hole and crank the engine.
• Compare the reading to the manufacturer's specifications; if low, further investigation is needed for potential internal engine issues.
