how to fix a P0302 code on my Toyota RAV4 XA40 (2013-2018)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative terminal of the battery to prevent electrical shorts.
• Ensure the engine is cool to avoid burns during inspection.

2. Inspect and Replace Ignition Components

• Tools Required: Socket set, torque wrench, spark plug socket, ratchet, pliers.
• Remove the engine cover, if applicable, for access.
• Disconnect the electrical connector from the ignition coil on cylinder 2.
• Remove the bolt securing the ignition coil and carefully pull it out.
• Inspect the spark plug by removing it using a spark plug socket. Check for wear or fouling.
• Replace the spark plug if it shows signs of wear or damage (use OEM or equivalent parts).
• Install the new spark plug and torque it to the manufacturer's specification (typically around 13 lb-ft).
• Reinstall the ignition coil and secure it with its bolt, then reconnect the electrical connector.

3. Check and Replace Fuel Injector (if necessary)

• Tools Required: Fuel injector puller (if needed), cleaning supplies for injector ports.
• Locate the fuel rail and disconnect the fuel line (use a rag to catch any fuel spills).
• Remove the bolts securing the fuel rail and carefully lift it, taking care not to damage the injectors.
• Remove the injector from cylinder 2 and inspect for clogs or damage.
• If faulty, replace the injector with an OEM part and ensure proper sealing with new O-rings.
• Reinstall the fuel rail and reconnect the fuel line.

4. Final Assembly

• Reconnect any components or wiring previously removed.
• Reinstall the engine cover if applicable.
• Reconnect the battery terminal.
