Why does the cam sensor not send a signal to the ignition coil?

Since, the Ignition Control Module really doesn’t send a physical signal (like the Crank or Cam Sensor does to the Switching Device) to the Ignition Coil (s). Why? Well, because the term ‘Switching Signal’ is just a descriptive name for the turning on and off of the primary current passing thru’ the Ignition Coil.

Can a bad crankshaft sensor stop a car?

Driving with a failing crankshaft position sensor can be difficult and potentially dangerous. It could lead to long-term vehicle damage and expensive repairs, or even stop the car from working at all.

Which is the triggering signal for the crank sensor?

Since the Crank Sensor (or Cam Sensor) is the one producing this Triggering Signal; I refer to it as the Triggering Device. First of all the signal that the Ignition Module (or Fuel Injection Computer) sends the Ignition Coil for it to start sparking is the Switching Signal.

How does the crank sensor control the ignition module?

The ignition module starts to turn On and Off the ignition coils in their proper firing order to create spark, after the crank signal arrives. This On/Off action is the Switching signal referred to above. Under 400 RPM’s, the ignition control module controls spark timing without the help of the fuel injection computer.

What happens if the crankshaft position sensor is not creating a signal?

And so, if the Crankshaft Position Sensor isn’t creating a Signal, then the measurable/testable effects of this condition are but not limited to: The Triggering Device (whether it’s the Ignition Control Module or the F.I.
