Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fuel pressure gauge, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems, and allow the engine to cool before handling components.

2. Addressing Error Codes

Step 1: Use the OBD-II scanner to identify the specific trouble codes. Note the codes and research their meanings.
Step 2: Clear the error codes and take the vehicle for a test drive to see if the check engine light returns.

3. Inspecting and Replacing Components

Step 1: If codes indicate an issue with the fuel system, check the fuel pressure using a fuel pressure gauge.
- Sub-step: If pressure is below specifications, replace the fuel pump or clean the fuel filter.
Step 2: If the air filter is dirty, remove the air filter housing and replace the air filter with a new one.
Step 3: If the oil level is low or the oil is dirty, perform an oil change, replacing the oil filter and using the recommended oil type.

4. Electrical System Check

Step 1: Use a multimeter to check battery voltage; it should read between 12.4V and 12.7V when not running.
Step 2: Inspect the ground connections and wiring harnesses for any signs of corrosion or damage. Repair or replace as necessary.
