DTC CODE READER? GOOD OR BAD THAT IS THE QUESTION

Should parts be replaced based on Diagnostic trouble codes?
Absolutely not! Although code readers can give you a general idea
of the system needing attention, keep in mind other driveability concerns can trigger false codes to be set. Only after proper testing of suspected components should the repairs be made, its been our experience that some people think that the trouble code tells the whole story and that is far from the truth, Rather than spend your hard earned money on parts that may be good its always best to have the vehicle professionally tested, only then can a proper diagnoses be made, this could save you valuable time and money!
