DTC Trouble Codes P0000 to P0100 – Complete OBD2 Error Code List and Meanings

Introduction

Diagnostic Trouble Codes (DTCs) are standardized OBD2 fault codes used by vehicle manufacturers to identify problems in the engine, fuel system, emissions system, sensors, and electronic control modules. When a fault is detected, the Engine Control Module (ECM) stores a code and may illuminate the Check Engine Light (CEL).
