The check engine light: common causes and what to do
BOISE – When the dreaded “Check Engine” light comes on, it usually means that your vehicle needs immediate attention. But what kind?
Unlike a general maintenance reminder, a check engine indicator alerts the driver to a potential problem with the engine or the emission system. Issues can range from extremely simple to very problematic.
Six check engine culprits
The fuel cap may be loose or faulty. Tighten or replace as necessary.
Faulty oxygen sensors, which may misread the amount of unburned oxygen in the exhaust system.
Frequently the target of theft for the valuable metals they contain, a missing or damaged catalytic converter will result in reduced vehicle performance and efficiency. A problem with a catalytic converter may also be a sign that something else is wrong in the emissions system.
