The coronary arteries regulate the supply of blood to your heart muscle depending on how much oxygen your heart needs at the time, as indicated by: 1  The number of times your heart beats per minute (heart rate). 2  Your blood pressure. 3  The force of your heart's contractions.  The thickness of your heart muscle.
When your car's Check Engine light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap.
The CHECK ENGINE light (or SERVICE ENGINE SOON) will only come on when the engine management system has recorded a fault. In order to know what the fault is, we must use a code reader tool to check the stored fault(s). We do offer a fault code reader and reset tool that you can use to check the codes.
