Which component generates a timing signal for the ignition system?

The crankshaft position sensor plays a crucial role in generating a timing signal for the ignition system. This component continuously monitors the position and rotational speed of the crankshaft. By sending this information to the engine control unit (ECU), it helps determine the precise timing for the ignition spark. This is essential for ensuring that the fuel-air mixture within the engine cylinders is ignited at the optimal moment, thereby improving engine efficiency and performance.

The throttle position sensor primarily monitors the position of the throttle valve and helps manage the air-fuel mixture but does not provide a timing signal for ignition. The camshaft position sensor, on the other hand, is involved in timing the fuel injection and determining the position of the camshaft, which indirectly affects timing but is not the primary source of the ignition timing signal. Finally, the oxygen sensor measures the level of oxygen in the exhaust gases to assess combustion efficiency, serving more for emission control than for ignition timing.
