my Honda Pilot YF3 (2016-2022) feels like it’s losing power, why?

Solution

1. Preparation

• Gather tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before working on any components.

2. Fuel System Inspection

• Sub-steps:
  1. Remove the fuel pump relay from the fuse box.
  2. Connect a fuel pressure gauge to the fuel rail.
  3. Turn the ignition to the "ON" position (do not start) and check the pressure reading; it should match the manufacturer specifications (typically around 30-50 psi).
  4. If pressure is low, inspect the fuel filter for clogs and replace if necessary.

3. Air Intake System

• Sub-steps:
  1. Remove the air filter housing cover and inspect the air filter; replace if dirty.
  2. Check for any cracks or loose connections in the intake hoses.
  3. Clean the throttle body using throttle body cleaner and a soft cloth.

4. Ignition System

• Sub-steps:
  1. Remove the ignition coils and inspect for signs of damage or corrosion; replace as needed.
  2. Check the spark plugs for wear; replace if they are worn or fouled (recommended gap for Pilot spark plugs is usually 0.043 inches).
  3. Reinstall the ignition coils and ensure they are seated properly.

5. Exhaust System Inspection

• Sub-steps:
  1. Inspect the catalytic converter for any signs of blockage or rattling.
  2. Check exhaust pipes for leaks or damage.
  3. If blockages are found, consider replacing the catalytic converter.
