my Toyota RAV4 XA50 (2019-2024) has a P0302 code what should I check

Solution

1. Preparation

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

2. Inspect Spark Plug

• Remove the ignition coil cover (if applicable).
• Disconnect the ignition coil connector from cylinder 2.
• Remove the ignition coil using a socket set.
• Remove the spark plug using a spark plug socket.
• Inspect the spark plug for wear, fouling, or damage.
• Replace the spark plug if necessary with the manufacturer-recommended part.

3. Check Ignition Coil

• Visually inspect the ignition coil for cracks or signs of overheating.
• Test the ignition coil with a multimeter for proper resistance (consult specifications for your model).
• Replace the ignition coil if it fails the test.

4. Inspect Fuel Injector

• Disconnect the fuel injector connector for cylinder 2.
• Use a noid light to check for signal to the injector while cranking the engine.
• If no signal is present, trace wiring back to the ECM for faults.
• If the injector is suspected to be clogged or faulty, remove and clean or replace it.

5. Perform Compression Test

• Remove the spark plug from cylinder 2.
• Screw in the compression tester and crank the engine.
• Record the compression reading and compare to specifications.
• If compression is low, further investigate potential internal engine issues.
