Monitor Real-Time Data: Observe live sensor readings like engine RPM, coolant temperature, and oxygen sensor voltage.
Perform Emissions Tests: Ensure your vehicle meets environmental standards.
Access Vehicle Information: Retrieve VIN, mileage, and other important data.

While the OBD2 port is relatively durable, several situations may necessitate its replacement:

Physical Damage: Bent or broken pins due to forceful plugging or accidents.
Corrosion: Exposure to moisture or harsh weather conditions.
Electrical Issues: Short circuits or wiring problems.
