I'm sure the bottom right is the crank sensor and the left is the knock sensor. Am I right?

I've never heard of a knock sensor, what is it's purpose?

Apart from detecting knocks before some wag posts that!

it sends a signal to the ecu I.E "pinking" the fuel mixture is wrong and the sensor picks up the vibrations and sends it to the ECU to correct etc

Good info thanks. Just bought a 147 (non runner) I got a 'p0335' error code with my 'Alfaobd' (Rpm sensor??)

I replaced my crank sensor but didn't bother with the knock sensor. Never heard anything about it playing up so left it to do its stuff.
