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

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the battery to avoid any electrical shorts during repairs.

2. Inspect and Replace Spark Plug

• Remove the ignition coil from cylinder 2.
• Unscrew and remove the spark plug from cylinder 2 using a spark plug socket.
• Inspect the spark plug for signs of fouling or damage. Replace with an OEM spark plug if necessary (Torque: 13-15 lb-ft).
• Reinstall the spark plug and ignition coil.

3. Test and Replace Ignition Coil (if necessary)

• If the spark plug is in good condition, test the ignition coil with a multimeter for resistance (specifications: approximately 0.4 to 2.0 ohms).
• If the ignition coil is defective, replace it with an OEM component (Torque: 80-100 lb-in when reattaching).

4. Clean or Replace Fuel Injector

• If problems persist, remove the fuel injector for cylinder 2.
• Clean the injector using an ultrasonic cleaner or replace it if cleaning does not resolve the issue.
• Reinstall the injector ensuring proper sealing.

5. Verify Compression

• If misfire issues persist, perform a compression test on cylinder 2.
• If compression is below specifications (typically 130-150 psi), further engine diagnostics may be required.
