my Honda Pilot YF4 (2023-Present) has poor fuel economy, what should I do

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Addressing Error Codes

• Use the OBD-II scanner to clear any error codes after repairs.
• If codes persist, refer to manufacturer specifications for further diagnosis.

3. Air Filter Replacement

• Locate the air filter housing, usually near the engine bay.
• Release the clips or screws holding the air filter cover.
• Remove the old air filter and install a new one, ensuring it fits snugly.
• Reattach the cover and secure it with clips or screws.

4. Cleaning the Throttle Body

• Remove the intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth or brush to clean the throttle body.
• Be cautious not to damage the throttle plate; ensure it moves freely.
• Reinstall the intake duct securely.

5. Inspecting Fuel System

• Use a fuel pressure gauge to check the fuel pressure against manufacturer specifications.
• Remove and clean fuel injectors if they are clogged; alternatively, replace them if necessary.
• Check and replace the fuel filter if it shows signs of clogging.
