Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, visual inspection tools, 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 system.

2. Inspect and Replace Gas Cap

Sub-steps:
1. Remove the gas cap and inspect for cracks or damage.
2. Clean the seal on the gas cap and the filler neck with a rag.
3. Reinstall the gas cap securely.
4. If damaged, replace with a new gas cap.

3. Check and Repair Vacuum Leaks

Sub-steps:
1. Inspect all vacuum lines visually for any cracks or damage.
2. Use a smoke machine to identify leaks if necessary.
3. Replace any damaged vacuum lines with new ones.

4. Inspect and Repair Exhaust System

Sub-steps:
1. Check for exhaust leaks visually, especially around the manifold and catalytic converter.
2. Tighten any loose connections or replace damaged gaskets.
3. If necessary, replace any faulty O2 sensors.

5. Test Battery and Alternator

Sub-steps:
1. Reconnect the negative battery terminal.
2. Use a multimeter to check the battery voltage; it should read between 12.4-12.7 volts with the engine off.
3. Start the engine and check the voltage again; it should read between 13.7-14.7 volts to confirm proper alternator function.
