What Causes the Check Engine Light to Come On?
For many drivers one of the most stomach dropping sights as you sit behind the wheel is the illumination of the check engine light. There is instant feeling that you are about to have to spend lots of money in order to restore whatever problem may have arisen. While there are some problems that can end up costing an arm and leg these problems usually come about due to the fact that smaller problems were ignored. As demonstrated by the first example of problems that will cause the check engine light to come on you will see how important it is to take your vehicle to the auto repair shop as soon as the light comes on.
Failed Catalytic Converter
One of the most expensive problems that can trigger the check engine light is the failure of the catalytic converter. Unfortunately, this statement can be a bit deceiving because in order for the catalytic converter to fail something else in the exhaust system must go wrong first, which would have turned the light on first. More than likely it would have been a very inexpensive fix, comparatively. For this reason it is always important to have check engine light diagnostics ran as soon as the light comes on.
Faulty MAF Sensor
If the mass air flow sensor malfunctions your vehicle will not be able to properly monitor incoming air flow. This can result in engine that is running rich, meaning too much gasoline is being burnt. The increased emissions will trigger the check engine light, informing you to get to the repair shop.
An exhaust leak will likely trigger the check engine light as well due to the fact that it can cause poor readings from the oxygen sensor. As the name suggests this sensor monitors exhaust for oxygen levels. An exhaust leak may result in high levels of oxygen being present in the fumes which would cause the sensor to increase fuel consumption.
Loose Gas Cap
Perhaps one of the best scenarios you could hope for if your check engine light comes on is a gas cap you forgot to tighten. If fuel vapors are detected escaping up the filler hose by the EVAP system the light will come on. The simple fix is tightening the cap or replacing it if it is broken.
As soon as the light comes on head to the shop. Waiting will most certainly result in bigger problems. For check engine light repair in South Beloit head to Integrity Auto Care.
