Top 5 Reasons Your Check Engine Light Might Be On

November 24th, 2022 by

If you’ve been driving in Wisconsin for any length of time, you know that winter can be harsh.  The cold temperatures, the snow and ice, and the salt on the roads can all take a toll on your vehicle. One thing you don’t want to worry about during winter is your check engine light. Unfortunately, the check engine light can come on for a variety of reasons, and some of them are more common during winter.

Here are the top 5 reasons your check engine light might be on during winter in Wisconsin:

  1. Low oil level – It’s important to check your oil level regularly, especially during winter. The cold temperatures can cause your oil to thicken, making it harder for it to circulate. This can lead to low oil pressure, which can trigger the check engine light.
  2. Dirty oil – In addition to being thicker, your oil can also get dirtier faster in winter. The combination of cold temperatures and all the salt and debris on the roads can cause your oil to break down and become contaminated. This can also trigger the check engine light.
  3. Frozen gas line – If you have a fuel-injected vehicle, your gas line can freeze in the cold weather. This can prevent fuel from reaching the engine, causing the check engine light to come on.
  4. Dead battery – The cold weather can also cause your battery to lose power faster. If your battery is getting old, it may not be able to hold a charge in the cold weather, causing the check engine light to come on.
  5. Faulty sensor – There are a variety of sensors on your vehicle that can fail, and one of them may be the cause of your check engine light. The cold weather can cause these sensors to fail, so it’s important to have them checked if your light comes on.

If your check engine light comes on this winter, don’t panic. Bring your vehicle to your local Chevy service center and let the experts take a look. They’ll be able to diagnose the problem and get you back on the road in no time.
