Tips for Handling Your Car’s Check Engine Light in Winter

November 6, 2025

Living in Greeley, Colorado, the winter season can be particularly tough on your vehicle. The cold temperatures and icy conditions can cause various issues, including triggering your car’s check engine light. When that dreaded light comes on during winter, it’s essential to take the right steps to ensure your safety and prevent further damage to your vehicle. In this article, we will provide you with valuable tips on what to do if your car’s check engine light illuminates during the winter months in Greeley.


1. Don’t Panic

Seeing the check engine light turn on can be alarming, especially when you’re driving in winter conditions. However, it’s crucial to stay calm and avoid panicking. The check engine light can indicate various issues, ranging from minor issues like a loose gas cap to more serious problems with the engine or emissions system.



2. Check Your Gas Cap

One of the most common reasons for the check engine light to come on is a loose or damaged gas cap. In cold weather, the gas cap seal can become less effective, triggering the light. Before assuming the worst, check your gas cap to ensure it is properly tightened. If the gas cap is loose, tighten it and see if the light goes off after a few driving cycles.


3. Monitor Your Temperature Gauge

During winter, it’s essential to keep an eye on your vehicle’s temperature gauge. If the check engine light is accompanied by the temperature gauge indicating overheating, pull over immediately and turn off the engine. Driving an overheated engine can cause severe damage. Wait for the engine to cool down before checking coolant levels and potential leaks.


4. Check Your Fluid Levels

Low fluid levels, such as oil, coolant, or transmission fluid, can trigger the check engine light. In cold weather, fluids can thicken, putting additional strain on the engine. Check your vehicle’s fluid levels regularly, especially during winter months, and top them up as needed. If you notice a significant drop in fluid levels, it’s essential to have your vehicle inspected by a professional.


5. Avoid Ignoring the Light

While it’s tempting to ignore the check engine light, especially during winter when driving conditions are challenging, it’s crucial not to ignore it. Ignoring the light can lead to more significant issues down the line, potentially leaving you stranded in the cold. Have your vehicle diagnosed as soon as possible to identify and address the underlying problem.


6. Schedule a Diagnostic Check

When the check engine light comes on, it’s best to schedule a diagnostic check with a qualified mechanic. A diagnostic scan can pinpoint the exact issue triggering the light, saving you time and money on unnecessary repairs. In Greeley, Colorado, CO Race Fab Auto Specialists offer comprehensive diagnostic services to help you identify and resolve check engine light issues promptly.


7. Drive Cautiously

If your vehicle seems to be running normally despite the check engine light, you can continue driving with caution. Avoid pushing your vehicle too hard or driving long distances until you have the issue resolved. Monitoring your vehicle’s performance and fuel efficiency can provide valuable information to the mechanic during the diagnostic check.


8. Prepare for Winter Emergencies

In Greeley, Colorado, winter weather can be unpredictable, so it’s essential to be prepared for emergencies. Keep a winter emergency kit in your vehicle, including essentials like blankets, water, a flashlight, and snacks. In the event that your check engine light leads to a breakdown in winter conditions, you’ll be better equipped to stay safe and comfortable while awaiting assistance.
