What Does a Check Engine Light in My Jeep Mean?


The check engine light is one of your Jeep's most consistently misunderstood wrangling lights. The check engine light is part of the onboard diagnostics system and displays a few discernable ways. When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. However, it could also warn of a severe problem that could cause serious damage to your engine and come with a hefty repair bill. Depending on the year and model of your Jeep, your check engine light illuminates in either an amber or red color and is part of the diagnostics system found on your vehicle. Below is a list of the most common reasons your check engine light can come on.

Do Check Engine Lights Turn off on Their Own?

The check engine light on your Jeep will frequently shut itself off if the issue or code that caused it to turn on is fixed. For example, if a loose gas cap causes your check engine light and tightens it, the light can turn itself off. However, if your light does not shut off after about 20-40 miles, it is likely a bigger problem, and you should make an appointment with DCH Chrysler Dodge Jeep Ram Service Department. 

Can Aftermarket Parts Cause the Check Engine Light in My Jeep to Come On?

Another reason your Jeep's check engine light is on could be Aftermarket parts. An aftermarket alarm, exhaust, or another item can wreak havoc on your Jeep if it's not installed correctly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even hinder the vehicle from starting. This is a side effect of using no-name parts and why it is always recommended you use OEM Mopar parts and accessories. 

If my Jeep has a Vacuum Leak, Will it Cause a Check Engine Light to Come On?

Vacuum Leaks are another reason your check engine light could be on. Every vehicle has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly jumps up, a vacuum leak could be the cause. Over time, vacuum hoses can dry out and crack excessively if exposed to imposing heat or extreme bleak. 

A Dead Battery Will Turn On your Jeeps Engine Light!

A low or dead battery will also cause the engine light to come on. The first purpose of your Jeep's battery is to deliver power to start your vehicle. It also acts as a surge protector for the car's computer and provides power for short-term use of things like lights, stereo, GPS, or wipers when the engine is off. The car battery is part of the starting system. Today's car batteries last much longer than they did a few decades ago and don't require maintenance. 

What is an O2 Sensor?

A faulty O2 sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your Jeep Wrangler's spark plugs. The O2 sensor sends data to the vehicle's onboard computer to represent the polite variety of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
