Your check engine light typically alerts you to an emergency issue or a recommended maintenance task. It can be nerve-wracking to see this warning light turn on, so explore the most common issues related to this light to troubleshoot this warning. Once you find the source of the issue, learn how to repair the issue and find out what size windshield wipers do I need by checking free online informational guides.
Why Is My Check Engine Light On?
This warning light is connected to your engine control unit, so there is a wide range of electrical and mechanical issues that can trip the light. Here are the top five causes of this light illuminating:
- Damaged oxygen sensor
- Bad catalytic converter
- Loose gas cap
- Spark plug issues
- Worn-out mass airflow sensor
A damaged oxygen or mass airflow sensor can’t properly measure the amount of air entering your engine and leaving through your exhaust system. This can affect the efficiency of your air/fuel ratio and cause stuttering, stalling, or other engine problems.
A loose gas cap is one of the easiest check engine light issues to solve. Simply tighten to replace your gas cap to seal your fuel system and allow the evaporative emissions system to work properly in containing and burning excess fuel vapors.
Spark plugs can operate for years without issues, but an inefficient gap or damaged plug can’t ignite your air/fuel mixture properly. A complete engine tune-up can adjust the gap or replace the inefficient sensors necessary to keep your engine running.
These are just the most common reasons your warning light may be on. If you’re still wondering, “why is my check engine light on?” then it’s time to have the error code read. An error code reader is free for use at your local auto parts store or is available for purchase to check the code at the convenience of your garage. These readers connect to your engine control unit and give you a phrase and code number that point you to the particular system that is damaged or working inefficiently. There may be a broken part or a loose wire, but understanding the affected system can take hours out of your troubleshooting time and help you locate the spare parts you need.
Simple Checks You Can Make to Make Sure Your Wiper Blades Are Installed Properly
Now that you have the serious maintenance issues taken care of, check out your wiper blades to make sure they are working properly. Inspecting windshield wipers may not seem like an essential maintenance step, but damaged, loose or inefficient wipers can affect your vision in-climate weather.
Visually inspect your blades to see if there is any damage. If you have conventional blades, worn-out rubber can leave the metal rod exposed. Over time, this can leave scratches on your windshield.
