If you’re like most drivers, you probably don’t know what to do when your check engine light comes on.
Many people panic and think that their car is about to break down. The truth is, a check engine light doesn’t always mean there’s something wrong with your vehicle.
However, if you ignore the light or try to fix it yourself, you could end up doing more damage and costing yourself more money in the long run.
Here are common reasons why your car’s engine light is on:
Engine Issues
When the check engine light comes on, it can be because of any number or combination of your car’s motor problems.
A control module will monitor operation via sensors. If something goes wrong in those areas, you’ll get this message displayed on front seat monitors.
Transmission Problems
Your car’s transmission is a complicated system that does not just shift gears. It also affects tailpipe emissions, so if it detects problems with the control module or any other parts, you will see your check engine light come on.
Emissions Equipment Issues
There are many onboard emissions equipment on modern vehicles that protect the environment.
The list goes from exhaust gas recirculation system, catalytic converter, and more to ensure no harmful toxins enter our air quality.
But there’s always a chance something could fail, which will turn your check engine light on.
Powertrain Controls and Sensors Problems
Modern cars are full of sensors, modules, and networks that keep running smoothly. But if something goes wrong with any one part of this complex system, then you could trigger the check engine light.
Air/Fuel Delivery Issues
Your car’s engine needs the correct amount of air and fuel to run correctly. When it gets too much or less, there will be problems with its performance because this can cause an inaccurate reading from sensors which then turns on your check engine light.
Ignition System Issues
The ignition system powers your engine and will turn on the check engine light if there’s a problem.
However, the spark plugs, coil packs, and other parts of this crucial process must be in good working order for it to work correctly- which means that you’ll need a check engine light expert near you like Accurate Service Complete Auto Care in Tucson, AZ.
How can an auto repair service shop near you help you with Check Engine Light Diagnosis?
When the check engine light comes on, your car’s computer will store a corresponding diagnostic trouble code (DTC) in its memory. A professional mechanic can connect devices like scan tools and readers via OBD ports to retrieve these codes for diagnosis purposes.
With the code as a starting point, your mechanic will use different troubleshooting techniques to determine what is causing it. They may also conduct additional diagnostic tests, and if that doesn’t work, return for more repairs.
