Some common issues that result in the malfunction indicator light turning on in Dodge vehicles include the need for an oxygen sensor replacement and a gas cap error. If these issues are not resolved, drivers may end up causing problems for their vehicles, such as reducing fuel efficiency.
The light may also indicate that the catalytic converter needs a replacement. If this error is not resolved, the vehicle may not pass emissions tests, and drivers may experience their vehicles running at higher temperatures and burning through fuel at a quicker rate. Sometimes the mass airflow sensor needs a replacement as well, and if this is not resolved, drivers may experience lowered fuel economy.
