What Does a Car Diagnostic Test Tell You?


A car diagnostic test can reveal a number of problems associated with your vehicle's transmission, oil tank, gas tank, exhaust system, or other components. Today's vehicles are designed with computer processors, microchips and sensors that can be linked to a computer which scans the vehicle's operating systems to pinpoint exactly where a problem may exist. Let your auto repair technician do the scan as they are trained to read the codes that will tell them what may be wrong with your vehicle.

A Car Diagnostic Test will answer the four questions below:

  1. What is the emissions level of your vehicle? This is how you know if you are being good to the environment or not. Your mechanic can test the health of your exhaust system and determine whether or not you need a car tune up.
  2. Are there faults in the PCM (power-train control module)? These faults are indicated with a flashing light on the dashboard. If there is a fault, there could be a number of potential problems looming that can be fixed while they are small.
  3. What is the idle speed stress? When the engine of your car is running too fast, too slow, or stalling, there might be a problem with the air control valve. If there a leak in the engine vacuum, your engine will have to work harder to perform.
  4. Are any problems with your transmission? If small problems can be taken care of before you notice the symptoms, you can avoid costly transmission repair in the future.

Performing a car diagnostic test usually takes less than an hour and can save your mechanic a lot of time troubleshooting a problem. You, the vehicle owner, can save a lot of money because you don't have to pay for repairs performed on a "trial-and-error" basis.

The next time the “Check Engine' light appears in the dashboard, do you know what is wrong?
