DTCs typically consist of five characters: a letter followed by four numbers. The letter indicates the system affected:

• P: Powertrain (engine, transmission)
• B: Body (interior, airbags)
• C: Chassis (brakes, suspension)
• U: Network (communication systems)

The first number indicates whether the code is generic (0) or manufacturer-specific (1). The remaining characters provide further details about the specific fault.

5.3. Common DTC Examples

• P0300: Random/Multiple Cylinder Misfire Detected
• P0171: System Too Lean (Bank 1)
• P0420: Catalyst System Efficiency Below Threshold (Bank 1)
• P0101: Mass Air Flow Circuit Range/Performance Problem

5.4. How to Interpret DTCs

1. Read the Code: Use a car diagnostic scanner to retrieve the DTC.
2. Research the Code: Consult a reliable database (like the one at CAR-TOOL.EDU.VN) or repair manual to understand the code’s meaning.
3. Diagnose the Problem: Perform tests to identify the root cause of the issue.
4. Repair the Vehicle: Fix the problem and clear the DTC.
5. Verify the Repair: Ensure the code does not return after the repair.
