Solution

1. Preparation

Gather tools and parts necessary for inspection and repair.
Tools Required: OBD-II scanner, socket set, multimeter, vacuum gauge, cleaning supplies.
Safety Warning: Disconnect the battery before working on electrical components.

2. Address Fault Codes

Use the OBD-II scanner to retrieve and note down any error codes.
Clear the codes and take the vehicle for a test drive to see if they return.

3. Inspect and Clean the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body. Ensure that the throttle plate moves freely.
Reinstall the intake duct and ensure all clamps are secure.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter in the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter and remove it.
Install a new fuel filter, ensuring it is oriented correctly, and reconnect the fuel lines.

5. Inspect Electrical Connections

Check battery terminals for corrosion and ensure they are tight.
Use a multimeter to test battery voltage; it should read between 12.4V to 12.6V with the engine off.
Inspect wiring harnesses for any signs of wear or disconnection.

6. Test Drive

After completing repairs, take the vehicle for a test drive to ensure that the power loss issue has been resolved.
