Why engine light on
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 safe to drive your car with the check engine light on?
Can you drive a car with the engine light on? It’s okay to drive for a few miles, but be sure to schedule an inspection of the engine as soon as possible. If the check engine light comes on while you’re driving, don’t panic! Pay attention and see if the car is driving any differently than normal.
Why is my engine light on but nothing seems wrong?
Do a brake and steering check. If nothing seems to be acting strange, then 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 a little loose. Or it could mean your catalytic converter needs to be inspected.
When should I be worried about check engine light?
Unlike a Temperature or Oil Pressure light, a Check Engine light is usually not an urgent, “Stop right now or you may cause permanent damage!” type of situation, unless it is flashing. If the check engine light is flashing, a more severe problem has occurred.
Is check engine light serious?
When your car’s check engine light illuminates on your dashboard, it’s usually accompanied by a sinking feeling in the pit of your stomach. The light could be a minor issue, such as a faulty gas cap, or it could mean something more serious, such as a misfiring engine.
How long can you drive on check engine light?
When the check engine light is solid, you can typically drive the car for hundreds of miles without an issue. Of course, that depends on which code is stored in the vehicle’s computer. If an engine sensor is faulty, the car will usually use made up sensor values to keep running.
What does a solid check engine light mean?
A solid Check Engine Light can mean something like a loose gas cap, or it can indicate a more in-depth problem like a fuel, timing, or transmission issue. Get your car diagnosed, although the urgency isn’t the same as if the light was flashing at you.
