how to address the P0302 code in my Toyota RAV4 Fourth Generation (2013-2018)?

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Tools Needed: Socket set, spark plug socket, torque wrench.
• Remove the ignition coil from cylinder 2 by unscrewing the retaining bolts.
• Detach the connector from the ignition coil.
• Remove the spark plug using a spark plug socket.
• Inspect the spark plug for wear or fouling; replace if necessary with the manufacturer-recommended spark plug.
• Reinstall the spark plug, tightening to the specified torque (typically around 13 ft-lbs).
• Reattach the ignition coil to cylinder 2 and reconnect the electrical connector.

3. Test and Replace Ignition Coil

• Tools Needed: Multimeter for testing.
• Test the ignition coil's resistance using a multimeter (specifications can vary, consult service manual).
• If the ignition coil is faulty, remove it and replace it with a new one.
• Reinstall the ignition coil and reconnect the electrical connector.

4. Inspect and Replace Fuel Injector

• Tools Needed: Fuel injector removal tool, socket set.
• Disconnect the fuel injector connector for cylinder 2.
• Remove the fuel rail if necessary to access the fuel injector.
• Inspect the fuel injector for clogs or damage; clean or replace if necessary.
• Reinstall the fuel injector into the fuel rail and reconnect the electrical connector.
