What is the function of the following sensors:
A single one on the sump.
Two on the water pipe (casting) black and green.
One each on each of the cylinder banks.

Single one on the sump is the oil low level.
Two on the water pipe are ECU water temp and cold start injector sensor.
The two on the cylinder banks if at the front are the cam sensors, if they are in the valley they are the knock sensors.
