Check gauge light meaning on jeep [6 Easy Steps to Fix]

Jeep has been one of the leading companies building offroad vehicles since 1943. However, driving the SUVs or crossovers also includes the experience of a Check Gauge light, that’s a warning from your Jeep’s engine. When this light appears, your Jeep needs serious attention.  

Check gauge indicates that the gauges (one or more) are detecting unusual responses from the system – e.g. low oil pressure, blown fuse, wiring problem, or it can even be faulty sensors. In that case, the ‘Beep’ source indicates the main concern.

If gauges are not working properly, it could indicate a serious problem that needs to be addressed. So, let’s discuss checking the gauge light so we can dig in when the situation demands.

What Is The Check Gauge Light Meaning On Jeep?

If you are a Jeep owner, the check Gauges’ light might be something you will face. But what does this light mean? The ‘Check gauges’ light is generally concerned with the gauges of your Jeep. 

The most common gauges in a Jeep are the tachometer, oil pressure, speedometer, fuel level etc. Each of these gauges provides vital information about the health of your engine and other systems in the vehicle.

The “Check Gauges” light serves as a reminder to inspect your Jeep’s gauges and ensure that everything is within normal operating parameters. 

If any of the gauges read abnormally high or low, there could be a problem. This causes the Check Gauge light to illuminate. In that case, make an appointment with an expert to diagnose and repair the problem.

Check your gauges is typically used as a cautionary phrase. It means that you should check the levels of liquids and gasses in your car or other vehicles on a regular basis. 

Checking these levels can assist in preventing problems like engine overheating, oil leaks, and flat tires.

What causes the check gauge light to come on?

Anything concerned with the system of your Jeep can trigger the “Check Gauges” light. Ignoring this signal can severely damage your Jeep. So, having the probable reasons in mind is a good decision.

1. Defective Sensors

Sensors help to get different readings accurately according to the situation demand. When the sensors are faulty, they do the opposite things of their actual function. That triggers the Check Gauge light to beep.  

2. Faulty Charging System

The transition from the accelerator to the brake in your Jeep may cause the gauges to be mad. It may seem to be nothing but I would suggest that don’t overlook the issue.

3. Vacuum Leakage

The vacuum system of your Jeep is needed for various functions. If the system gets leaked or cracked, the system gets agitated. As a result, your Keep can get abnormally higher RPMs (in the tires), triggering the Check Gauge light.

4. Blown Fuse

Sometimes, the check gauge light in your Jeep can turn on depending on the blown fuses. Blown fuses may cause harm to the Check Gauges light.

5. Wire-ning

Sometimes, you get an irregular Check Gauge light warning. In that case, there can be a variety of reasons. For example, wiring problems (defective electrical connection), engine failure or sticky valves.

6. Faulty Components

If the gauges look just fine, and the alarm seems to be a false warning, then check the PCM/ECM/ECU. The warning can be because of the faulty condition of the PCM/ECM/ECU.

7. Defective Thermostat

A leak or any other issue can cause defects in the thermostat. In that case, the machine fails to maintain coolant flow to the engine. Besides, it may cause a contaminated supply of coolant. This causes overheating of the engine.

8. Low Oil Pressure

The Check Gauge light in your Jeep can beep because of lowered oil pressure. In that case, oil light blinking along with Check gauges.

The reasons behind can be –

  • Oil leakage by oil filter
  • Faulty oil pressure sensor
  • Low oil temperature
  • Worn parts
  • Clogged filter
  • Insufficient oil
  • Decreased graded oil 

How Do You Fix A Check Engine Light?

If the Check Gauge Light comes up when you’re driving, please don’t panic. First, take your Jeep to a safer side and park it. Then look for the probable issues –  

1. Check the Engine First

Go through the warnings on the other gauges and try to determine the one beyond range. This may happen if the engine is overheated, or the fuel cap is loose. Issues in the charging system, or running out of fuel can be a headache too. The poor condition of PCM/ECM can also be an issue.

2. Check the electrical components

Poor electrical connections can be a reason, so checking relevant components is a must. 

If any component is loose or damaged, it is possible that it is a reason for the illumination. Check the battery, wire, dirt etc. Keep being updated so that huge problems may not show their face.

3. Replace the faulty fuse

If a blown fuse exists in your Jeep, detect it. It is easy to find blown fuses – they are blackening or broken metal strips. Replace them with similar quality.

4. Fix the Sensor

If the Check Gauge light of your Jeep beeps because of faulty sensor, Identifying the defective one or sending the unit and changing it with the new one can help to fix the light.

5. Fix the Thermostat

To fix the thermostat you can

  • Add coolant to the reservoir
  • Find if the thermostat is damaged or engine coolant temperature sensor

6. Having a grip on low oil pressure

For Jeeps, you should be regular to maintenance. If not, the warning could indicate that it’s been a long time to see the doctor. First, you should check on the easy-to-fix parts. 

Else, check on the other factors. Knowing the reason can make it easy to fix the oil pressure. Following steps can make it a cup of tea.

  • Check the wiring harness connected to the sensor
  • Use a mechanical oil pressure gauge and have test drive to check if it’s with the sensor
  • Sudden huge change in pressure means faulty oil pump, replace it immediately.


It’s hopefully been a good discussion. Still, arousal of some questions is definitely normal. I hope going through these answers can help you out.

Can you drive a jeep with check gauges light on?

If it’s a warning from the tire pressure monitoring system (TPSM). You can continue driving your Jeep for another 100 miles or so (keep your speed low). If it’s for low engine oil, you should not continue driving and should take your car to a mechanic ASAP.

Why does my jeep check gauge light come on when I brake?

The brakes in your Jeep have the potential to turn on the check engine light by failing the braking system, reasons include low levels of brake fluid, worn brake pads, improper vehicle operation etc. Heavy lifting on the vehicle causes brake wear and tear.

What is the most important warning light on a jeep?

It’s the oil. Engine Oil Level or Oil Pressure Light indicate that the oil temperature has risen, the oil level or the oil pressure has dropped. Immediately turn off the engine. If oil pressure is lost, the engine can be severely damaged.

What does yellow check engine light mean on a jeep?

When a computer detects a problem in the electronic-control system it cannot resolve, it illuminates a yellow light that is labeled with “check engine”, “service engine soon”, or “check powertrain” or the word a picture ‘check’ with an engine-illustrated light.


Stay calm. That’s the best thing to do first. Check the specific parts I have mentioned to analyze the situation properly. Correct them only if you are sure how-it-works.

If the gauge is affected in a mild way, then try to take it to a nearby pump station. Otherwise, stop beside a safe place and you can use your mechanical gauge. Otherwise, you can ask for help from a mechanic. 

Never try to take any major step without expert supervision. Last but not the least, never run through the road when you have a severely damaged engine system – or your Jeep may face a huge and permanent engine complication.
