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. If the light comes on and stays on, get your vehicle into our service center as soon as possible. However, if the check engine light is flashing, pull over as soon as you safely can, and arrange for your vehicle to be seen right away. This could warn of a severe problem that could cause serious damage to your engine if you keep driving. 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.

A Dead Battery Will Turn On Your Jeep's 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 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 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.
