Why Is the Check Engine Light on in a Dodge Ram?

The primary reason that the check engine light illuminates in a Dodge Ram truck is a loose gas cap. If this kind of a warning is ignored, it can lead to serious damage that will be expensive to repair.

If the gas cap has been tightened and the check engine light remains illuminated, then the car should be taken to a safe place for further examination. The other dashboard gauges should be checked and the vehicle should be inspected for signs of problems, such as overheating of the engine, low oil pressure, low oil level and poor condition of the lights. If all of these components are working properly, the owner can continue using the vehicle with a reduced speed and load, but an appointment should be scheduled with a service provider to inspect it.

The vehicle should be inspected immediately if it experiences performance problems, overheating or loss of power. If it feels unsafe to drive, it should be parked and a tow service or roadside assistance should be called to take the car to an auto repair professional. A blinking check engine light indicates a problem that requires urgent attention. In some late-model vehicles, this blinking light is an indication of an engine misfire that causes the unburned fuel to be dumped into the exhaust system.
