What are common check engine light issues?


When your check engine light illuminates, it doesn't automatically indicate that your engine is about to suffer catastrophic failure. Still, it's smart to get to the shop for computerized diagnostics so that any developing issues can be identified and addressed ASAP. At Willie Automotive & Towing Service, our local mechanics are experts at identifying and repairing car problems that trigger the check engine light. When the check engine light turns on, make sure you don't ignore it!

Common Reasons the Check Engine Light Turns On

In many cases, a faulty catalytic converter is the reason that the check engine light has illuminated. Signs of catalytic converter trouble include worsening acceleration, decreasing gas mileage, and a smell like rotten eggs. It's important that your catalytic converter is working properly so that your vehicle isn't excessively polluting. An oxygen sensor issue can cause problems with the catalytic converter, and may also trigger the check engine light. A faulty oxygen sensor can also cause rough idling. Another sensor that can trigger the light is the MAF sensor. When a MAF sensor is failing, your car may stall shortly after you fire it up. A MAF sensor problem can also cause decreasing acceleration.

Faulty spark plugs can also cause the check engine light to come on. If your vehicle was made in the last twenty years, then it can probably go 100,000 miles before needing new plugs, while older cars tend to need plug replacement more often. Faulty ignition coils can also trigger the light. Symptoms of bad ignition coils include engine stalling, as well as worsening fuel-efficiency.

If your check engine light turns on, there are a couple of other possible triggers to consider. For one, a faulty battery can trigger the light if it causes low voltage at the computer. Also, a loose or missing gas cap could cause the light to turn on. Whenever you fill up your tank, it's important that you return your gas cap to a fully secure position. Otherwise, fuel is liable to evaporate before your engine gets the chance to run on it.
