There are many triggers for this — a faulty O2 sensor, a solenoid malfunction, an engine misfire, a loose fuel cap, an airbag problem, and so on. So what is the problem? The best way to narrow it down is to take a look at the DTC code. Not sure what that is? There are tons of DTC codes, each representing specific vehicle problems. Initially, there were several versions of onboard diagnostics interfaces that largely varied depending on the vehicle manufacturer. These codes help cars stick to emission regulations and save the environment. A vehicle manufacturer may create their own DTC codes to add to the universal code list if certain vehicle models need it. But the question is, what do these OBD codes mean? And how do you read them?

When an issue occurs, the check engine light is activated and a DTC diagnostic trouble code is generated to pinpoint the problem. DTC stands for diagnostic trouble code. Also known as a DTC engine code or engine fault code, the codes are usually five characters long: typically one letter followed by four numbers. Diagnostic trouble codes were originally developed by the Society of Automotive Engineers SAE to help fleet vehicles comply with emission regulations under the Clean Air Act.

DTC faults or Diagnostic Trouble Codes are the codes generated and stored by a vehicles On-board Diagnostic system indicating that a part or section of the vehicle is malfunctioning. DTC Codes identify a specific problem area. Technicians can use the codes to diagnose the problem in causing the OBD to report the fault. On-board diagnostic systems OBD have undergone a considerable evolution from when they were first introduced in the US, and so have the protocols that the computer uses to respond to the DTC faults. Every vehicle with an OBD also comes with a manual for fault codes. The manual is what a professional or any knowledgeable driver can use to determine the systems, components and circuits that he or she should test to diagnose the vehicles fault. This is mostly not the case because in a modern automobile, the ECU is responsible for monitoring a dozen other sensors. When a DTC reports a sensor fault, the fault will mostly be resulting from two main spots; the system being monitored by the sensor, or the wiring to the sensor. For example an MAF sensor that has accumulated dirt over time might cause a vehicle to overcompensate in its fuel-trim adjustments which consequently will result in a report of fuel mixture problems by the oxygen sensors.
