question 1. b
question 2. neather
question 3. b
I need the rest of question 4 please
4 The rear wheels of a vehicle keep locking up when the brakes are applied.
Which of these is the most likely to cause this?
The metering valve
The pressure differential switch
The proportioning valve
The brake switch
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.
It is often part of the combination valve.
7. Technician A says that welding is an excepted method of cracked engine block repair.
Technician B says that metal pinning/stitching is an accepted method of cracked engine block repair.
8. Two technicians are discussing flywheel resurfacing.
Technician A says a mark should be placed on the flywheel/crankshaft before removal.
Technician B says if too much of the surface is removed from the flywheel damage will occur to the release bearing.
9. Limited slip differentials have all of the following characteristics except:
Both wheels drive during acceleration.
Chatter may occur from worn parts.
They often use special fluids.
Both wheels drive while cornering
10. Two technicians are discussing vacuum assist brake boosters.
Technician A says to pump the brake pedal numerous times to relieve the vacuum from the brake booster.
Technician B says after relieving the vacuum to tart the engine and the pedal should move slightly toward the floor.
11. A vehicle lacks power at high speeds and under heavy engine load conditions.
Which of these is the most likely cause?
A stuck-closed fuel pressure regulator
An intake valve adjusted to tight
Low fuel pump delivery volume
A stuck-open egr valve
4. proportioning valve
6. It is a hight sensing device
9. both wheels drive while turning
11. low fule pump delivery volume
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
