Im bored so I decided to break down a DTC for you.
When you run a generic code reader that just pulls codes it will give you a letter followed by 4 number
For arguments sake ill just start with a fake code
P1234
The P stands for the system affected
P=Powertrain (engine and transmission)
B=Body (hvac or SRS)
C=Chassie (honda currently to date has no chassie DTC)
U=Network (ony avalible for vehicals that are CAN equiped)
The first diget is the standardized code Digets 0 and 2 are SAE Standerd codes. Digets 1 and 3 are non-standerd code set by the manufactor
So our code P1234 is a powertrain code set by Honda
The second diget is the sub system affected. SAE defines the third diget.
0, 1, and 2 are fuel and air monitoring, components of emission control
3 is Ignition system, misfire (wires spark plugs distributor pack, coil)
4 Auxilary emission control (catylitic converters)
5 Vehical speed, idle control, Auxilary input
6 Computer and Auxilary input
7, 8, and 9 Transmission
So DTC P1234 is a problem with the powertrain, code is a Honda specific code, problem in the fuel and air monitoring system.
The last two digets are grouped togather to indicate the component or section of the sub system that has the fault.
