what does it mean if my Ford F-150 has a P0302 code

Solution

1. Preparation

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

2. Inspect and Replace Spark Plug

• Remove the engine cover if applicable.
• Use a spark plug socket to remove the spark plug from cylinder 2.
• Inspect the spark plug for signs of wear, fouling, or damage.
• Replace the spark plug with the manufacturer-recommended part and torque it to specification (usually 12-15 lb-ft).

3. Check and Replace Ignition Coil

• Disconnect the ignition coil harness connector for cylinder 2.
• Remove the ignition coil using a socket or wrench.
• Inspect for cracks or damage on the coil.
• If defective, install a new ignition coil and ensure it is seated properly.

4. Inspect and Replace Fuel Injector (if necessary)

• Disconnect the fuel injector connector for cylinder 2.
• Remove the fuel rail (if required) to access the injector.
• Check the injector for clogs or leaks.
• If faulty, replace the fuel injector with a new part.

5. Reassemble and Reconnect

• Ensure all components are reassembled correctly, including any removed engine covers.
• Reconnect the battery cable.
