my Toyota Camry Eighth Generation (2018-present) has a P0302 code, what does that mean?

Solution

1. Preparation

• Use a spark plug socket to remove the spark plug.
• Inspect the spark plug for wear and replace if necessary.
  • Tools Required: Spark plug socket, ratchet, torque wrench.
  • Torque Specification: Install the new spark plug to the manufacturer's recommended torque (typically around 13-15 ft-lbs).

3. Inspect and Replace Ignition Coil
