5 Technician A says the crankshaft position sensor monitors the crankshafts speed and rotation.
Technician B says a permanent magnet sensor has three wires
Who is correct?
Both Technician A and b
Neither Technician A or b
6. All of these are true about the metering valve except:
It is used on most vehicles with front disc and rear drum brakes.
It is a height sensing device.
It gives the rear brakes a chance to over come the springs and engage with the front brakes.

Becouse these are test questions 1 of my answers is incorect, can you tell me which one?
just question 10 coudn't that be both because I think I had saw a video with some one pumping the brake and then starting the engine and it moved slightly I'm I right.
just give me the reason for that one please
The spring in the vacuum booster would keep the pedal where it should be
even after you start the vechicle
you still have not found the incorrect answer\
i wont know until after i take the test i just wanted someone more knowlegable then me to answer these thats all as long you got most of them correct
