what does it mean if my Toyota Camry Eighth Generation (2018-present) shows a P0302 code

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery (negative terminal) to ensure safety.
• Allow the engine to cool down before starting work.

2. Inspect and Replace Spark Plug

• Tools Required: Spark plug socket, ratchet, torque wrench
• Remove the ignition coil covering (if applicable) to access the spark plug.
• Remove the spark plug using the spark plug socket and ratchet.
• Inspect the old spark plug for wear, fouling, or damage.
• Install a new spark plug, ensuring it is gapped correctly (typically 0.043 inches for Toyota).
• Torque the spark plug to the manufacturer’s specification (around 13 lb-ft).

3. Inspect and Replace Ignition Coil

• Tools Required: Socket set
• Disconnect the electrical connector from the ignition coil.
• Remove the ignition coil securing bolts.
• Pull out the ignition coil and inspect it for cracks or damage.
• Replace with a new ignition coil if necessary.
• Reinstall the ignition coil and reconnect the electrical connector.

4. Check Fuel Injector

• Tools Required: Fuel injector cleaning kit (if applicable)
• Disconnect the fuel injector connector.
• Remove the fuel injector from cylinder 2.
• Inspect the injector for clogs or damage.
• Clean the injector using a fuel injector cleaning kit or replace it if defective.
• Reinstall the fuel injector, ensuring proper seating and connection.

5. Perform Compression Test (if needed)

• Tools Required: Compression gauge
• Remove the spark plug from cylinder 2.
• Insert the compression gauge into the cylinder head.
• Crank the engine and observe the compression reading.
• Compare the reading to the manufacturer's specifications (usually around 170-200 psi for the Camry).
• If readings are low, further investigation into mechanical issues may be necessary.
