DTC Trouble Codes P0201 to P0396 – Complete OBD2 Error Code Guide

Introduction Car error codes list

Diagnostic Trouble Codes (DTCs) from P0201 to P0396 are primarily related to:

1. Air/Fuel Mixture Control and Metering

• Fuel Injectors

• Fuel Pressure System

• Air Intake Sensors

• Oxygen Sensors

• Emission Control Components

2. Ignition System and Engine Misfire Detection

• Ignition Coils
