Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery for safety (negative terminal first).
Ensure the work area is clean and free from hazards.

2. Address Fault Codes

Sub-step 1: Clear the error codes using the OBD-II scanner.
Sub-step 2: Take the vehicle for a test drive to see if the error codes reappear.
Sub-step 3: If the codes return, note the specific codes for further investigation.

3. Inspect and Replace Components

Sub-step 1: If error codes indicate misfire, replace faulty spark plugs or ignition coils. Remove the engine cover if necessary, and use a socket wrench to replace components.
Sub-step 2: For air intake leaks, inspect the intake hoses and replace any damaged sections.
Sub-step 3: If the fuel cap is defective, replace it with a new one.

4. Test Fuel Pressure

Sub-step 1: Connect a fuel pressure gauge to the fuel rail.
Sub-step 2: Turn the ignition to the "ON" position without starting the engine and note the pressure reading.
Sub-step 3: Compare the reading to manufacturer specifications; replace the fuel pump if pressure is low.

5. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all tools are removed from the engine bay before starting the vehicle.
