my Toyota RAV4 has a P0302 code, what does this mean?

Solution

1. Preparation

• Gather tools and parts for repair.
• Disconnect the battery to prevent electrical shorts.
• Ensure the engine is cool before starting work on components.

2. Replace Spark Plug

• Remove the ignition coil from cylinder 2.
• Remove the spark plug using a spark plug socket and ratchet.
• Inspect the old spark plug for wear or damage.
• Install a new spark plug, ensuring it is gapped correctly according to specifications (typically around 0.043 inches for most Toyota engines).
• Torque the spark plug to the manufacturer's specifications (usually around 13 lb-ft).

3. Inspect and Replace Ignition Coil

• If the spark plug is in good condition, inspect the ignition coil for cylinder 2.
• Disconnect the electrical connector from the ignition coil.
• Remove the ignition coil from its mounting position.
• Install a new ignition coil and reconnect the electrical connector.
• Ensure it is seated correctly and secure.

4. Check Fuel Injector

• Remove the fuel injector from cylinder 2 after disconnecting the fuel line (use caution as fuel may spill).
• Inspect the injector for clogs or damage.
• If necessary, replace the fuel injector with a new one.
• Reinstall the fuel injector and reconnect the fuel line securely.

5. Reconnect Battery and Clear Codes

• Reconnect the battery terminals.
• Use the OBD-II scanner to clear the P0302 code from the vehicle's computer.
