what does error code P0302 mean for my Toyota RAV4

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a flat surface, with the engine off and cool.
• Disconnect the battery negative terminal to prevent any electrical shorts.

2. Inspect and Replace Ignition Components

• Sub-steps:
  1. Remove the engine cover (if applicable) using a socket set.
  2. Disconnect the ignition coil connector for cylinder 2.
  3. Unbolt and remove the ignition coil from cylinder 2.
  4. Inspect the spark plug for wear. If necessary, remove it using a spark plug socket.
  5. Replace the spark plug with a new one, ensuring it is gapped to the specification (typically around 0.044 inches for most Toyota models).
  6. Install the new ignition coil, ensuring it is seated properly and reconnect the connector.

3. Check and Clean Fuel Injectors

• Sub-steps:
  1. Remove the fuel rail (if necessary) to access the injector for cylinder 2.
  2. Inspect the injector for clogs or damage.
  3. Clean the injector using an appropriate cleaning solution or replace it if necessary.
  4. Reinstall the fuel rail and ensure all connections are secure.

4. Perform Compression Test

• Sub-steps:
  1. Remove the spark plug from cylinder 2.
  2. Insert a compression gauge into the spark plug hole.
  3. Crank the engine to take a reading and compare it to the manufacturer’s specifications.
  4. If compression is low, further investigation into the engine’s internal components may be required.
