DTC Fault Codes List – Complete OBD-II Diagnostic Trouble Code Guide

Introduction

Diagnostic Trouble Codes (DTCs) between P0201 and P0300 are commonly related to:

1. Fuel Injector System

• Injector circuit faults

• Fuel delivery problems

• Injector electrical failures

2. Fuel Pump and Fuel Pressure Control

• Fuel pump circuits

• Fuel pressure regulators

• Fuel system monitoring

3. Turbocharger and Boost Control Systems

• Turbo boost pressure

• Wastegate controls

• Boost solenoids

4. Ignition and Engine Misfire Systems

• Spark plugs

• Ignition coils

• Cylinder misfires

When these faults occur, the ECU stores a DTC and turns ON the Check Engine Light (MIL).
