Check Engine Light Diagnostics in Norwalk, CT
Let Us Check Your CEL
Check Engine Light Reasons
Your check engine light (CEL) can come on for several reasons. It comes on whenever the computer inside your car identifies a problem with your engine or transmission. The presence of this light can indicate either a minor fix or a major situation. Several common issues can cause your check engine light to come on. Your gas cap may be loose, or your engine may have problems. If your oxygen sensor isn’t working or your mass airflow sensor is damaged, that can also trigger this light to come on. Your CEL may also be trying to tell you that your catalytic converter is having issues. If your spark plugs, spark plug wires, or ignition coils are having issues, these things can also set off your check engine light. Your CEL may also come on if you accidentally fill your tank with the wrong kind of gas, like diesel for a gas car or vice versa. But what do you do when your check engine light comes on?
Don’t Ignore the CEL!
No matter why your check engine light is shining, don’t ignore it. It’s important to understand that the check engine light differs from the maintenance required light. When your maintenance light comes on, you should definitely come in for maintenance services as soon as possible. However, the check engine light is a sign that your car has more pressing issues. It’s essential to have your check engine light diagnosed as soon as possible. Some car makes, and models have a CEL that shines in different colors to determine how bad the problem is. If your check engine light flashes on and off or is red, that’s a sign that you should prioritize getting your car checked out by a professional immediately. A solid yellow or orange light may indicate a less severe problem, but again, it’s not something you should ignore! Make an appointment to get the problem diagnosed and fixed as soon as you can. Ignoring the check engine light can lead your car to develop even worse problems down the line.
