A Jeep’s Check Gauges light basically means that one or more of the Jeep\u2019s essential gauge readings are inaccurate or out of range. This generally indicates issues such as a malfunctioning engine’s power system, insufficient engine oil, or other faulty but necessary subsystems that the gauges monitor. <\/strong><\/p>\n\n\n\n

The root cause of this issue could be more complex and serious. And, disobeying this warning might significantly harm your Jeep. It might also leave you stuck on the road. So, it is necessary to discover how to deal with it and prevent it.<\/p>\n\n\n\n

What Does the Check Gauge Light Mean?<\/h2>\n\n\n\n

Gauges are a kind of device used to monitor several functions in a Jeep. These gauges are not only used in Jeeps, but also in most modern vehicles. <\/p>\n\n\n\n

It\u2019s an important system for any vehicle’s safety and performance. Here, if any of these gauges indicate an issue, it triggers the “Check Gauges” light on the dashboard. <\/p>\n\n\n\n

Basically, it’s a warning signal that the Powertrain Control Module<\/a> (PCM) displays on the vehicle’s dashboard. It helps the driver know about potential vehicle issues.<\/p>\n\n\n\n

Based on the model and vehicle, this check gauge light could be orange, yellow, or flashing red. The yellow light indicates a moderate risk, and the red indicates a serious issue.<\/p>\n\n\n\n

Which Gauges are Most Likely to Trigger the Check Gauge Light?<\/h2>\n\n\n\n

The check gauge light could be turned on for several reasons. Here, some reasons could be serious, whereas others could be less important. <\/p>\n\n\n\n

And, if you know which issues are triggering this light, you will be able to fix the specific issue. <\/p>\n\n\n\n

But if you don\u2019t have any idea and take your vehicle to a mechanic shop, they might fool you. <\/p>\n\n\n\n

So let’s take a closer look at a few significant gauges and how they turn on your Jeep\u2019s “Check Gauges” light.<\/p>\n\n\n\n

Coolant Temperature Gauge:<\/h3>\n\n\n\n

This gauge continuously monitors engine coolant temperature. Basically, every vehicle has a standard temperature rating. <\/p>\n\n\n\n

And, when this coolant temperature crosses its standard limit, this gauge instantly detects it and triggers the check gauge light. <\/p>\n\n\n\n

In general, an ideal coolant temperature falls between 195 and 220 degrees Fahrenheit.<\/p>\n\n\n\n

Oil Pressure Gauge:<\/h3>\n\n\n\n

To ensure proper operation, every vehicle’s engine requires a certain amount of oil pressure. <\/p>\n\n\n\n

And, if this oil pressure drops below a specific limit (25 to 65 PSI), an engine’s motor won\u2019t get the sufficient lubrication it needs.<\/p>\n\n\n\n

At this time, the oil pressure gauge triggers the “Check Engine Light. Along with the Check Gauges Light, you may also notice an oil pressure warning light.<\/p>\n\n\n\n

Fuel Level Gauge:<\/h3>\n\n\n\n

A fuel level indicator\/gauge generally monitors the fuel level. Basically, this gauge has two parts: one is a sensor unit, and another is an indication unit.<\/p>\n\n\n\n

Here, the sensing unit\/device measures the quantity of fuel inside the tank and transmits this data to the indication unit.<\/p>\n\n\n\n

When the sensing unit detects low fuel levels or the sensing unit itself malfunctions, it triggers the check gauge light.<\/p>\n\n\n\n

Tire Pressure Gauge:<\/h3>\n\n\n\n

Jeep has a TPMS<\/a> to continuously monitor its tire pressure. This system uses pressure monitoring sensors which are installed in each tire to get specific pressure levels. <\/p>\n\n\n\n

Here, when any tire\u2019s pressure becomes lower than the manufacturer’s standards (32 to 36 PSI), its sensor triggers the check gauge light. In this situation, a yellow dash indicator light will also turn on.<\/p>\n\n\n\n

Battery Voltage Gauge:<\/h3>\n\n\n\n

This gauge measures the voltage level of the Jeep\u2019s battery. And if the voltage reaches below the standard range, the gauge thinks that the battery is not charged well or not functioning properly. <\/p>\n\n\n\n

In this situation, it illuminates the check gauge light. Low battery voltage can be caused by several reasons. <\/p>\n\n\n\n

Such as a malfunctioning charging system, a faulty alternator, an old battery that isn’t working correctly, or weak\/broken connections.<\/p>\n\n\n\n

Trip Odometer Gauge:<\/h3>\n\n\n\n

A functioning trip odometer gauge calculates the distance the car has traveled since its last reset. And a faulty trip odometer gauge might cause the check gauge’s light to illuminate. <\/p>\n\n\n\n

Tachometer Gauge:<\/h3>\n\n\n\n

A device called a \u201ctachometer\u201d<\/a> is used in every vehicle to measure an engine’s operating speed. <\/p>\n\n\n\n

Here, when this gauge finds a mismatch with the default RPM value or malfunctions, it then triggers the check gauge light.<\/p>\n\n\n\n

Air\/Fuel Ratio Gauge:<\/h3>\n\n\n\n

An Air\/Fuel ratio (AFR<\/a>) gauge monitors an internal combustion engine’s air-fuel ratio. While operating an engine’s ideal AF ratio<\/a> should be around 14.7:1. <\/p>\n\n\n\n

Here, if the air\/fuel ratio goes above or below the typical range, their monitoring gauge illuminates the check gauge light. Typically, it’s a sign that indicates that the engine’s oxygen sensors or fuel system aren’t working properly.<\/p>\n\n\n\n

How Do I Reset the Check Gauge Light?<\/h2>\n\n\n\n

Usually, when you solve the specific issue, the check gauge light will automatically turn off. <\/p>\n\n\n\n

But, if the light stays on even after fixing the issue, you may have to apply manual reset techniques.<\/p>\n\n\n\n

To properly reset the check gauge light on a Jeep, follow these step-by-step guidelines:<\/p>\n\n\n\n
