Car diagnostics refers to the process of identifying and troubleshooting issues in a vehicle using specialised equipment. Modern vehicles are equipped with an On-Board Diagnostics (OBD) system, which provides data about the vehicle’s performance and any potential issues. When a problem arises, a diagnostic tool can be connected to the car’s OBD port to read trouble codes and identify malfunctions. Common areas of diagnostics include:
- Engine Performance: Identifying issues with fuel efficiency, engine misfires, or reduced power.
- Transmission Issues: Checking for problems with shifting, slipping, or abnormal transmission behavior.
- Braking System: Diagnosing ABS or brake warning light issues.
- Emission Control: Identifying issues related to the vehicle’s exhaust system or sensors, such as oxygen sensors or catalytic converters.
- Sensors and Modules: Identifying faulty sensors, such as the mass air flow sensor, throttle position sensor, or camshaft position sensor.
- Warning Lights: Reading trouble codes associated with dashboard warning lights (e.g., check engine light).
