what does P0302 code mean for my Toyota Camry Eighth Generation (2018-present)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface, and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Spark Plug

• Sub-steps:
  1. Remove the engine cover if applicable.
  2. Locate and remove the spark plug wire or ignition coil from cylinder 2.
  3. Use a spark plug socket to remove the spark plug from cylinder 2.
  4. Inspect the spark plug for wear; replace if the electrode is worn or fouled.
  5. Install the new spark plug, ensuring it is gapped correctly according to specifications (typically 0.043 inches for the Camry).
  6. Reattach the ignition coil or spark plug wire securely.

3. Check and Replace Ignition Coil

• Sub-steps:
  1. If the spark plug is in good condition, test the ignition coil using a multimeter (check for primary and secondary resistance according to specifications).
  2. If the ignition coil is faulty, remove it from the engine by unscrewing it from the mounting bracket.
  3. Install the new ignition coil, ensuring it is seated properly and connected to the spark plug.

4. Inspect and Clean Fuel Injector

• Sub-steps:
  1. Remove the fuel injector connector from cylinder 2.
  2. Use a fuel injector cleaning kit or a multimeter to check its operation.
  3. If the injector is clogged or malfunctioning, replace it with a new unit.
  4. Reconnect the fuel injector connector and ensure it clicks into place.

5. Perform a Compression Test (if necessary)

• Sub-steps:
  1. Remove the spark plug from cylinder 2.
  2. Insert the compression gauge into the spark plug hole.
  3. Crank the engine and record the compression reading.
  4. Compare the reading with the manufacturer’s specifications; if low, further mechanical inspection may be needed.
