why does my Ford F-150 14th Generation (2021-2024) have a check engine light and low power

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 terminal to prevent electrical shorts.

2. Scan and Identify Codes

• Use the OBD-II scanner to read trouble codes.
• Document the codes for reference in further diagnostics.

3. Air Intake Inspection

• Remove the air filter and inspect it for dirt or blockage.
• Check air intake hoses for cracks or loose connections.
• Replace any damaged components and reinstall the air filter.

4. Fuel System Check

• Connect a fuel pressure gauge to the fuel rail.
• Turn the ignition to the ON position (do not start the engine) and check the fuel pressure against specifications.
• If low, inspect the fuel pump and fuel filter for issues. Replace as necessary.

5. Ignition System Inspection

• Remove spark plug wires and inspect for damage.
• Replace any faulty ignition coils or spark plugs.
• Reinstall components ensuring proper torque specifications are followed.

6. Exhaust System Examination

• Inspect the exhaust system for signs of blockage or damage.
• If a clogged catalytic converter is suspected, perform a backpressure test and replace if necessary.
