The code will help you to identify and fix the issue within the car.Д®ach trouble code consists of one letter and four digits, such as P1234.

When the vehicle detects an issue, it will activate the corresponding trouble code.ДЄ vehicle stores the trouble code in itвЂ™s memory when it detects a component or system thatвЂ™s not operating within acceptable limits.

Each code corresponds to a fault detected in the car. Worn out spark plugs, ignition wires, coil(s), distributor cap and rotor (when applicable), Incorrect ignition timing, Vacuum leak(s), Low or weak fuel pressure, Improperly functioning EGR system, Defective Mass Air Flow Sensor, Defective Crankshaft and/or Camshaft Sensor, Defective Throttle Position Sensor, Mechanical engine problems (i.e.Editor's note: This post has been updated in March 2020 for accuracy and the latest information.Дiagnostic Trouble Codes or OBD2 Trouble Codes are codes that the carвЂ™s OBD system uses to notify you about an issue.
