Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, basic hand tools
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to reset the computer system.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note down any error codes.
Cross-reference the codes with a repair manual or online database for diagnosis.

3. Inspect and Repair Identified Issues

For code related to a faulty sensor:
- Remove the faulty sensor using a socket or wrench.
- Install the new sensor as per manufacturer specifications, ensuring proper torque.
For a loose gas cap:
- Tighten the gas cap until it clicks.
For oil or coolant issues:
- If levels are low, top off with the appropriate fluids (engine oil or coolant).
- If excessively low or leaking, identify the source of the leak and repair as necessary.

4. Reset the Check Engine Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the error codes.
Start the engine and allow it to idle for a few minutes.

5. Final Inspection

Visually inspect for any signs of leaks or abnormalities after the repair.
Ensure all components are securely fitted and there are no loose wires.
