Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery cable and allow the vehicle to sit for at least 10 minutes to reset the system.
Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, and basic hand tools.

2. Resolve Fault Codes

Use the OBD-II scanner to read the error codes.
- Note the specific codes and refer to a repair manual for detailed information on each code.
- Clear the codes and see if they return after a test drive.

3. Repair or Replace Faulty Components

Based on the diagnostic codes retrieved:
- If the code indicates a faulty O2 sensor, replace it by removing the old sensor using a socket wrench and installing the new one, tightening it to the manufacturer's torque specifications (usually around 30 lb-ft).
- If spark plugs or ignition coils are faulty, remove the engine cover and replace them as needed, ensuring to gap new spark plugs according to specifications before installation.

4. Recheck and Finalize

Reconnect the battery cable.
Perform a final check of all connections.
Start the engine and monitor for any abnormal sounds or warning lights.
