Error codes are five digits codes that help the driver identify possible reasons why the check engine light is flashing.
The check engine light is used to alert the driver that there’s a fault that needs to be fixed it doesn’t categorically state the problem.
The function of the Onboard diagnostic scanner is to read and point out all the codes on a car with the specific location of the fault.
There are four categories of Error codes: P, B, C, and U, representing Powertrain, Body, Chassis, and Unknown, respectively.

The P (Power train) Error codes are the most popular among them since it concerns the engine and other components that make up the proper functionality of the car.
However, the C Error Codes also play an essential role in the car’s makeup, since the chassis is the base that upholds and provides the frame for the vehicle.
In this article, I’ll provide you with the complete list of Error codes starting with the C prefix and the fault location of the error code.
List of OBD-II C Error Codes
C Error Codes range from C0000 down to C4000, and there is a section for generic and manufacturer-specific errors.

C0000 to C1000 and C3000 to C4000 are generic codes set to international standards (ISO/SAE) to create a secure life cycle in the automotive sector.
While codes between C1000 to C3000 are manufacturer specific, the codes here may differ from the ones set by your car manufacturers.
Nevertheless, consult your car manual or manufacturer’s website to find the tailored fix for your car.
Without wasting much time, here’s a complete list of OBD-II C trouble codes.
