Unfortunetaly, NO.
Fault codes usually tell you there's something wrong with the electric circuit of a part.
But the cause can be wiring, a fuse, the part itself and in some cases even the ecu.
When you get codes like misfires of mixture problems there can be dozens of reasons.
So, reading the code is one thing, interpreting it and reparing the car is something else.
