Engine Fault Code Check

Your engine runs smoothly based on a complex system of interconnected mechanical components that work in unison. Even just a small malfunction can trigger the check engine light to signal a glitch in the system. Diagnosing an engine problem requires the skill and experience of a qualified mechanic. FaultCodeCheck.com is listed ODB , ODB-I and ODB-II codes with their meanings, reasons and how to fix them. These engine fault codes divided 4 parts : Diagnostic Body (B) Trouble Code ,Diagnostic Network (U) Trouble Code ,Diagnostic Chassis (C) Trouble Code and Diagnostic Powertrain (P) Trouble Code.

Regardless of age, mileage, make, or model, occasional engine problems are an inevitable part of car ownership. While proper maintenance may help reduce the need for car repairs it is not a guarantee that a car will not break down. As a car accumulates miles the chances of engine problems increase; however, not all engine problems are serious.

Types of OBD2 Fault Codes?

There are 2 main types of OBD2 codes, generic and manufacturer-specific.

Generic codes are universal and mutually agreed by all auto manufacturers to make sure that a generic code means the same thing on all cars from all makers.

1st digit
P = Powertrain
B = Body
C = Chassis
U = Network

2nd digit
0 = Standard
1 = Manufacturer specific

3rd digit
1 = Emission management
2 = Injector circuit
3 = Ignition
4 = Auxiliary emission
5 = Vehicle speed & idle control
6 = Computer & output circuit
7 = Transmission
