how can I fix the P0301 code in my Ram 1500 DT (2019-Present)

Solution

1. Preparation

• Gather tools and parts required.
• Disconnect the battery and allow the engine to cool.

2. Replace Spark Plug

• Tools Required: Socket set, torque wrench, spark plug socket.
• Remove the ignition coil by unscrewing the bolts and disconnecting the electrical connector.
• Use the spark plug socket to remove the spark plug from cylinder 1.
• Inspect the old spark plug; if it's worn or fouled, replace it with a new one.
• Install the new spark plug by hand to avoid cross-threading, then torque to manufacturer specifications (typically around 13-16 lb-ft).

3. Inspect/Replace Ignition Coil

• Reinstall the ignition coil if it appears undamaged. If cracked or faulty, replace it with a new ignition coil.
• Reconnect the electrical connector and ensure it is secure.
• Torque the mounting bolts to manufacturer specifications.

4. Clean/Replace Fuel Injector

• If the fuel injector shows signs of clogging, remove it using appropriate tools.
• Clean the fuel injector using a fuel injector cleaner or replace it if necessary.
• Reinstall the injector ensuring O-rings are intact and seated properly.

5. Compression Test

• Reattach the spark plug and ignition coil if they were removed.
• Perform a compression test; if the compression is low, further diagnostics may be needed to assess valve or piston issues.
