Crankshaft and Camshaft sensor

[antonyj]

Apart from the bleeding obvious!, what is the difference in these two sensors?
What does one provide that the other cant??

Thanks for any help

In a 4-stroke engine, the crankshaft goes round twice for each complete engine cycle. So you need a cam sensor to work out which half of the engine cycle you are in.

Cheers Pete,

By cycle , you mean completing the firing order?

So do you need both for something like the Omex or MS systems?

You need both if you're using sequential injection or coil-per-plug ignition.

Ahh right of course, so wasted spark and batch fire can run off the cranks sensor
