Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, vacuum gauge, torque wrench
Safety Warnings: Disconnect the battery before starting any electrical work.

2. Address Code-Specific Issues

Sub-step 1: After retrieving the error codes, research each code to determine the specific components or systems affected.
Sub-step 2: If the code indicates a faulty sensor (e.g., oxygen sensor), remove the sensor using the socket set, and install a new one.
Sub-step 3: Clear the error codes using the OBD-II scanner after replacing any faulty components.

3. Check and Replace Vacuum Hoses

Sub-step 1: Inspect all vacuum hoses for cracks or disconnections.
Sub-step 2: Replace any damaged hoses with new ones, ensuring proper routing.

4. Inspect and Replace Air Filter

Sub-step 1: Remove the air filter housing using the socket set.
Sub-step 2: Replace the old air filter with a new one, ensuring it fits securely.

5. Test Battery and Charging System

Sub-step 1: Use a multimeter to check the battery voltage; it should read between 12.4V and 12.7V when the vehicle is off.
Sub-step 2: Start the vehicle and check the voltage again; it should read between 13.7V and 14.7V to indicate proper charging.
