A customer came into HomeTowne Auto Repair & Tire with a check engine light on.
They stated that there were no problems with driving the car, but the light had come on a couple days earlier.
This is one problem that can be addressed through diagnostic testing.
Diagnostic testing goes beyond reading a code or looking over a vehicle.
Anybody can take a car to have a code read, or check it out themselves with a flashlight. Diagnostic testing enables technicians to dig deeper into the problem.
Codes are like zip codes — they tell us where in the neighborhood you’re supposed to be. However, further investigation is necessary, because they can mask other issues.
For example, there could be a code for a catalytic converter and we could say, “OK. We read the code. Replace it.” But the code could really be caused by oxygen sensors that aren’t reading correctly.
Through diagnostic testing, technicians are able to determine the actual reason for a failure or problem, which can help you save money in the long run.
