Most Common Problems
There are multiple reasons why that check engine light might be on. The most common culprit is a simple one: a loose gas cap. Not tightening the gas cap will send a signal to your car that something is wrong. If tightening your gas cap doesn’t make the light go off, it’s time to look at other issues.
Worn out spark plugs are another cause for the check engine light. When your plugs fail to send the proper electric signals to your car, the computer diagnostics will flag it. If the oxygen or airflow sensor is damaged or old, that will also cause the light to come on. Replacing it will fix the issue. A more severe issue that can cause the check engine light to come on is a bad catalytic converter. This is a repair you can’t afford to put off, as it can cause additional problems if ignored. Regular repairs and maintenance on your vehicle can prevent many of these problems.
The Car Computer Experts
The topic of car computers can often leave drivers confused, but it’s not so complex anymore. In the past, car computers were much more complicated. Before 1996, each carmaker had its own computer codes, and repair shops had to carry multiple computers. Now, car computer trouble codes are standardized for each make and model. The OBD-II comes equipped with all the standard codes. At Auto Clinic of Maryland, we have the computers ready to diagnose your car trouble. Our ASE-certified technicians are experts in reading the codes and correctly repairing your car.
