What would cause the check gauge light to come on?
The check gauge light is one of those dashboard warnings that can cause immediate concern for drivers. It’s designed to alert you to potential issues with your vehicle’s systems, but understanding what triggers it can help you address the problem quickly and avoid costly repairs. At Kevin's Autos, with years of experience in car maintenance and repair, we’ve seen this light come on for a variety of reasons. Let’s dive into the most common causes and what you should do if it happens to you.
What Does the Check Gauge Light Mean?
The check gauge light is a warning indicator on your dashboard that signals an abnormal reading from one or more of your vehicle’s gauges. These gauges monitor critical systems such as oil pressure, battery voltage, engine temperature, and fuel levels. When the light comes on, it’s your car’s way of telling you to pay attention to these systems immediately.
Common Causes of the Check Gauge Light
Here are the most frequent reasons why the check gauge light might illuminate:
- Low Oil Pressure: If your oil pressure gauge shows a low reading, it could indicate insufficient oil in the engine or a problem with the oil pump. Driving with low oil pressure can cause severe engine damage.
- High Engine Temperature: An overheating engine is a serious issue. This could be caused by a coolant leak, a malfunctioning thermostat, or a failing radiator.
- Low Battery Voltage: If the battery voltage gauge drops, it might mean your alternator is failing, your battery is weak, or there’s an issue with the electrical system.
- Low Fuel Levels: While this is less critical, running out of fuel can leave you stranded. The check gauge light may come on if your fuel gauge is nearing empty.
What Should You Do When the Check Gauge Light Comes On?
If you notice the check gauge light, follow these steps to address the issue:
- Check the Gauges: Look at all the gauges on your dashboard to identify which one is showing an abnormal reading. This will give you a clue about the underlying problem.
- Pull Over Safely: If the issue seems critical, such as low oil pressure or high engine temperature, pull over as soon as it’s safe to do so. Continuing to drive could cause further damage.
- Inspect the Problem: Check the oil level, coolant level, or battery connections, depending on the gauge that’s indicating trouble. If you’re unsure, it’s best to call for professional assistance.
- Visit a Mechanic: Bring your vehicle to a trusted auto repair shop, like Kevin’s Autos, to diagnose and fix the issue. Ignoring the check gauge light can lead to more significant problems down the road.

- Have your battery and alternator tested during routine service visits.
- Inspect your vehicle’s belts and hoses for wear and tear.

What does it mean when the check gage light comes on?
An illuminated check gauge light means that one or several gauge readings aren't within the normal range. Low oil pressure, a loose gas cap, and thermostat issues are common reasons why the check gauge light can pop up. You'll still be able to drive your vehicle with an illuminated check gauge light.
What is the first thing to check when the check engine light comes on?
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.

Can a bad gas gauge cause check engine light to come on?
Yes, bad gas can potentially cause your check engine light to blink on and off. Here's how it works: Fuel Quality: Poor-quality fuel, which may contain contaminants or incorrect octane levels, can lead to incomplete combustion. This can trigger the engine control unit (ECU) to detect misfires.
