Check Engine Light
Check Engine Light is the warning light that illuminates on the dash when there is a problem within the engine or emissions systems. Check engine light can also come on when there is a transmission problem. It is also known as " Service Engine Soon" t. Modern vehicles have a 16-pin connector under the dashboard where you can plug an OBD-II scanner and find out why your check engine light is on.
You can use a scanner such as the YOUCANIC UCAN-I scanner to find out why the check engine light is on and clear the codes after fixing the problem.
YOUCANIC Scanner allows you to:
- To read stored codes. Connect the scanner to the port under the dashboard. Turn the ignition ON but do not start the engine. Follow the instructions on the scanner.
- Clear fault codes and reset check engine light. It should only be performed after fixing the problem.
- Check if the vehicle is ready to pass the emission test.
What could cause the check engine light to come on?
A problem with either your spark plug wires or the spark plugs themselves could cause your check engine light to come on. Ignoring this problem may lead to a clogged catalytic converter, damaged ignition coils, or problems with your oxygen sensor.
Is it OK to drive with the check engine light on?
It depends on what is causing the check engine light to come on. If the check engine light is flashing, you should not continue to drive.
If the vehicle is not overheating and has not lost power, it is probably safe to drive it until you can get it into a mechanic. Sometimes the light may come on after fueling if the gas cap is loose. Or it could mean your catalytic converter is clogged. If the check engine light is constantly on, you may be able to drive if the vehicle has not lost power. Consult your mechanic for immediate help.
Should I worry if the check engine light is on?
We strongly recommend not ignoring the check engine light even if the vehicle runs and drives fine. At a minimum, use the YOUCANIC scanner to read the codes, which will give you a better idea of why the check engine light is on.
