Doctor, We Have A Problem!
Who am I? Every vehicle has one like me on its instrument panel, but most drivers prefer to ignore it. The answer: the warning light indicating an engine discrepancy, better known as the “Check Engine” light.
Never Ignore It
In fact, what should be taken note of and remembered is that the “Check Engine” light comes on in all kinds of situations, whatever their gravity level. First of all, it is important to know that a professional is required to uncover the problem using a scan tool.
A technician will connect a scan tool to your vehicle’s engine; this tool detects diagnostic codes in the operating chain. The scan tool’s analysis then issues a diagnosis from which the technician is in a position to pinpoint the root cause of the problem that triggered display of the “Check Engine” light on the dashboard. It is interesting to note that the technician cannot base the solution process exclusively on the problem’s root cause, since in many cases, several elements come into play.
Diagnostic Codes and Electrical Problems
Here is a concrete example of a diagnostic analysis. As part of his diagnosis, the technician receives a diagnostic code that starts with the letter “P”. It indicates a leak in the evaporative emission control system. However, it is necessary to conduct a few additional tests to identify the leak’s precise location, and finally seal it.
It can also happen that the “Check Engine” light’s display takes root at just a minor electrical problem, which the technician can quickly solve. Since passenger cars are more and more equipped with electrical even electronic systems, it makes sense that problems of this type are becoming more commonplace. Hence the importance of driving your vehicle over to a NAPA AUTOPRO centre when the “Check Engine” light shows up on your instrument panel; a certified technician will then analyze the diagnosis produced by the scan tool. In addition, all these data will be stored so as to allow tighter follow-up to be performed as part of regular maintenance visits.
