Here is a breakdown of what each digit of the OBD code means
(please keep in mind the explanation is for Standard OBD 2 ports and not per car manufacturers spec)
OBD II port on the Mazda MX-5 06-2011 is tucked under the driving wheel ,you really have to bend and twist to find it ,use a torch and really get under the wheel
First Character - System
The first character identifies identifies the system related to the trouble code.
P = Powertrain
B = Body
C = Chassis
U = Undefined
Second Digit - Code Type
The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles) or a manufacturer specific code.
0 = Generic (this is the digit zero -- not the letter "O")
1 = Enhanced (manufacturer specific)
Third Digit - Sub-System
The third digit denotes the type of sub-system that pertains to the code
