What causes a check engine light?
A camshaft sensor problem will usually trigger the check engine light. From there, you can do a diagnostic scan to suss out a camshaft issue, but it won’t tell you whether the problem is the sensor or the component it’s monitoring. That will take further digging. You may additionally notice problems with drivability.
How does an engine's precision work?
An engine’s precision is enabled by a system of car sensors that monitor components and conditions and interface with the electronic control unit (ECU), the vehicle’s main computer. The ECU receives input from sensors and makes an immediate call based on programming. It then sends a signal to an actuator that changes or maintains a condition, including air, fuel and spark, to reflect information from the sensors. If there is a mechanical problem and one of the components is faulty or broken, the sensors will let the ECU know to either adjust or alert you.
