When your check engine light comes on, you may be torn between utter panic and just wanting to ignore it and hope it goes away. That’s perfectly understandable. That same check engine light could come on for anything from a serious engine or transmission problem all the way down to a loose gas cap.
There’s a very common misconception that the trouble codes stored in your engine computer when your check engine light comes on will specifically identify a problem. It’s really more like pointing to the symptoms of a problem.
Think of taking your temperature. Say it’s 101. Your heat sensor – the thermometer – tells you that your temperature is out of the normal range. But it doesn’t tell you why you have a fever. Is it the flu or a sinus infection? You need more information or more tests.
For any given trouble code, there could be a number of causes. Your trained technician will take the trouble code as a starting point and begin a diagnostic process to determine the cause of the problem. Some problems take longer to solve than others.
When your engine management system logs a problem and illuminates the check engine light, your West Des Moines service technician at All Pro Servicenter will plug in a scanner, download the trouble codes, and go to work tracing the cause of the problem.
If your check engine light is flashing, it means that the problem could lead to serious damage. You should get to your local All Pro Servicenter as soon as possible to get the problem solved. If it’s on but not flashing, you have some time to get in at your convenience.
Your engine air filter is the filter that cleans the air before it’s burned in your engine. Many people in West Des Moines wonder how often they should change their engine air filter. The simple answer is ‘when it’s dirty’. That’s a function of how much air has passed through the filter, so your manufacturer will recommend a mileage interval for replacing the air filter. How dirty the air is will affect how quickly the filter needs to be replaced.
If you drive in West Des Moines where there’s lots of dust, pollution, or pollen, your engine air filter will get dirty more quickly and need to be changed sooner. That’s why we check the air filter with every full-service oil change at All Pro Servicenter. We can visually tell if the filter needs to be changed.
Your filter can only hold so much dirt. Once the filter is full, dirt will pass through to the engine. This dirt gums up the combustion chamber and hurts fuel economy and may cause damage. It can also contaminate the Mass Air Flow Sensor which will affect drivability and can be fairly expensive to replace.
A dirty air filter will also restrict the amount of air that gets to the engine, which hurts fuel economy. We can replace your engine air filter with one that matches the factory specifications or you can upgrade your filter for enhanced performance.
