how do I fix the P0302 code in my Ford F-150 13th Generation (2015-2020)

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Disconnect the battery to prevent electrical shorts.
• Allow the engine to cool before beginning work.

2. Inspect and Replace Spark Plug

• Tools Required: Spark plug socket, ratchet, torque wrench
• Remove the ignition coil from cylinder 2 by unbolting it and disconnecting the electrical connector.
• Remove the spark plug using the spark plug socket.
• Inspect the spark plug for wear or fouling.
• If necessary, replace the spark plug with a new one, ensuring to torque it to the manufacturer's specifications (typically around 13-15 lb-ft).

3. Inspect and Replace Ignition Coil

• Tools Required: Ratchet, socket set
• If the spark plug is in good condition, inspect the ignition coil.
• Replace the ignition coil for cylinder 2 if damaged or not functioning.
• Reinstall the ignition coil, ensuring the connector is securely attached.

4. Inspect Fuel Injector

• Tools Required: Fuel injector removal tool
• Disconnect the fuel rail to access the fuel injector for cylinder 2.
• Remove the injector and inspect it for clogs or damage.
• If necessary, clean the injector with a fuel injector cleaner or replace it with a new one.

5. Perform Compression Test

• Tools Required: Compression tester
• Remove the spark plug from cylinder 2 and install the compression tester.
• Crank the engine and note the compression reading. Repeat for accuracy.
• Compare the reading to the manufacturer's specifications. If low, further investigation into possible internal engine issues may be required.

6. Reconnect Battery and Clear Codes

• Reconnect the battery.
• Use the OBD-II scanner to clear the P0302 code and any other codes present.
