Where are OBD2 codes stored in a car?
Diagnostic trouble codes (or fault codes) are obd2 codes that are stored by the on-board computer diagnostic system. These are stored in response to a problem found in the car by the system. These OBD2 codes are stored when a sensor in the car reports a reading that is outside the normal/accepted range (Eg: fuel mixturetoo rich).
