When your car's internal computer identifies a problem with the engine or transmission, it turns on the check engine light. The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter.

What to do when your check engine light comes on

Once you notice your check engine light has come on, pay attention to how the car is driving. Does something feel off? If so, reroute yourself to the nearest mechanic to get the car checked out. If the car seems to be running fine, you can check a few things on your own before heading to the mechanic.

There are a couple of simple solutions if your check engine light came on after getting gas. A loose gas cap is one of the most common reasons for the check engine light to go on. Check that your gas cap is screwed on securely and that it's in good condition.

If you have a tank of bad gas in the car, your check engine light may come on. For example, if your vehicle is designed to run on premium gas (octane grade 91 to 94), the engine may struggle to run on regular gas (octane level 87). You can safely solve this problem by having a professional drain your gas tank. If you must drive until the tank is empty again, this may not cause severe damage, as long your car doesn't show signs of overheating or poor engine performance.

Do you suspect something else caused your check engine light to turn on? The most foolproof method to check the engine light is to read the diagnostic code in the car's internal computer. If you have experience working with cars, you can do this at home with an OBD-II scanner. Otherwise, head to your local service station where a mechanic can read the diagnostic code and determine the correct fix.

 

Why you shouldn't ignore your check engine light

The check engine light is sometimes confused with the maintenance required light, although the two are unrelated. The maintenance required light goes on when your car is due for routine service. Examples of routine services include an oil change. However, the check engine light is an indication that something unexpected has occurred.

 

ON-Board Diagnostic Trouble Codes

The list below contains standard diagnostic trouble codes (DTC’s)

that are used by some manufacturers to identify vehicle problems. The codes

provide below are generic codes that may not apply to all vehicles. Vehicle

manufacturers may use manufacturer specific DTC codes that are different

from the codes shown below. Foreign vehicles may also use DTC codes

different from the generic DTC codes. The Division recommends that

motorists not depend on the DTC codes in this list for vehicle repairs until

they confirm the generic DTC codes apply to their vehicles. The list below is

for information purposes only and is not intended for use in vehicle repairs.

 

OBDII identifies and communicates to technicians where and

what on-board problems exist. The first number in the DTC

indicates whether the code is an SAE generic code (applies to

all OBDII systems) or is specific to the vehicle manufacturer.

The remaining three numbers provide information regarding the

specific vehicle system and circuit. An analysis of a typical

OBDII code is shown below.

Following is a list of generic DTCs
