what does it mean when my Toyota Camry has a P0302 code

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plug

• Sub-steps:
  1. Remove the ignition coil from cylinder 2 by unscrewing any retaining bolts and disconnecting the electrical connector.
  2. Extract the spark plug using a spark plug socket and ratchet.
  3. Inspect the spark plug for wear or damage (replace if necessary).
  4. Install a new spark plug, ensuring it is gapped correctly per manufacturer specifications.
  5. Reinstall the ignition coil and reconnect the electrical connector.

3. Check and Replace Fuel Injector

• Sub-steps:
  1. Disconnect the fuel injector connector and remove the retaining clips.
  2. Pull out the fuel injector from the engine.
  3. Inspect the injector for clogs or damages and replace if necessary.
  4. Clean the injector ports and reinstall the new or cleaned injector.
  5. Reconnect the injector electrical connector.

4. Compression Test

• Sub-steps:
  1. Remove the spark plug from cylinder 2.
  2. Insert the compression tester into the spark plug hole.
  3. Crank the engine several times to get a reading.
  4. Compare the reading to the manufacturer specifications; replace the cylinder head gasket or piston rings if compression is low.

5. Final Checks and Reassembly

• Sub-steps:
  1. Reassemble any components removed during the inspection.
  2. Reconnect the battery.
  3. Clear the error codes using an OBD-II scanner.

Tools Required:

• OBD-II scanner
• Ratchet and socket set
• Torque wrench
• Spark plug socket
• Compression tester
• Fuel pressure gauge
• Noid light or multimeter

Parts Required:

• Spark plug (specific to Toyota Camry model)
• Ignition coil (if defective)
• Fuel injector (if defective)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Disconnect the battery before working on electrical systems.
• Allow the engine to cool before opening any components, especially around the fuel system.
