2015 Dodge Durango Check Engine Light, if it’s on, does it always mean there’s a problem?

No. The check engine light can come on for several reasons, but not all of them mean there’s a problem with your vehicle. It could be that you’re low on gas or that you need an oil change. More often than not, though, it’s something more serious like a bad oxygen sensor or catalytic converter. When the light comes on, it’s a good idea to have your vehicle checked by a mechanic to make sure there is no problem.

The check engine light can also stay on even if there are no problems with your car. This usually happens when you leave something like a fuel cap off or forget to plug in an accessory. The computer uses this sensor to determine how much fuel to inject into the engine. If it detects an irregularity, it will turn on the light.
