Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Address Diagnostic Trouble Codes (DTCs)

Sub-step 1: Using the OBD-II scanner, retrieve and document the DTCs.
Sub-step 2: Research the specific DTCs to identify the potential issues related to the engine.
Sub-step 3: Clear the codes from the system and perform a test drive to see if the light returns.

3. Inspect and Replace Components

Sub-step 1: If the DTC indicates a faulty sensor (e.g., oxygen sensor, mass airflow sensor), locate the component and disconnect the electrical connector.
Sub-step 2: Remove the sensor using the appropriate socket size and install the new sensor, tightening it to manufacturer specifications.
Sub-step 3: Reconnect the electrical connector securely.

4. Perform Maintenance

Sub-step 1: Replace the engine air filter if it is dirty. Open the air filter housing, remove the old filter, and install a new one.
Sub-step 2: Check and replace spark plugs if they show signs of wear (typically every 60,000 miles).
Sub-step 3: Inspect and replace any damaged vacuum hoses.

5. Reconnect Battery and Final Checks

Sub-step 1: Reconnect the negative battery terminal and ensure it's secure.
Sub-step 2: Start the engine and let it idle, monitoring for any abnormal sounds or vibrations.
