Check Engine Light Causes
Is your vehicle telling you to service your engine soon?
These are some potential reasons for why your check engine light is on:
- Your vehicle’s oxygen sensor has gone bad, burning more fuel than it should, or triggering problems with the spark plugs and catalytic converter.
- Your catalytic converter is damaged or malfunctioning, causing you to lose performance, burn more fuel than necessary, and/or make your car run on the hot side.
- The gas cap is loose, allowing fuel to evaporate and resulting in more frequent fill-ups.
- Spark plug damage is causing problems with oxygen sensors, ignition coils, and the catalytic converter. Mass Airflow Sensor
- Your mass airflow sensor is bad, reducing in power and fuel economy while damaging the catalytic converter, oxygen sensors, and spark plugs.
Diagnosing Your Engine Problems: The Process
Warning lights tell you something is wrong, but they don’t tell you what or where the problem is in the vehicle. We have technology that goes beyond the scanning code level to find out exactly why your check engine light is on in the first place.
If your check engine light is on in Marietta, GA, we can help.
Your mechanic will likely follow the following pattern of testing to determine your car’s trouble spots or specific areas that may need special maintenance:
1. Scanning Codes
By connecting diagnostics gear to your car, we can get the low-down on any codes your car’s computer may or may not be showing. This can give you and your mechanic an idea of what components may need to be serviced.
2. Verification Test
The verification test analyzes your vehicle’s engine vacuum, back pressure, emissions systems, and ignitions operations. This either verifies the information found while scanning codes, or provides new information to help us dial in the diagnosis.
3. Pinpoint Testing
As a final step in the diagnostic process, your mechanic may perform a circuit and component pinpoint test, including:
- testing mechanical and electrical components
- making visual inspections of potential problem areas
- conducting bi-directional control tests
With diagnostics complete, we’ll investigate recalls, technical service bulletins, and other information to look for patterns of malfunctions for your make and model.
Time for Repairs
Once everything’s been diagnosed, it’s time to make engine repairs.
A Final Note
If your technician completes every step of the diagnostic process and finds no problems, but your engine light is activated on your dashboard, there’s a consolation for going through this detailed process. If there’s no reason for the warning light to be on, your mechanic can easily deactivate it.
