Final Exam - Suspension and Steering Questions And Answers (Updated And Verified) 1500 psi - answerHigh pressure hoses have to be used on the high pressure side of the power steering system because pressures can reach as high as __________. 200 psi 750 psi 2500 psi 1500 psi False - answerAll power steering pumps have integral reservoirs. True or False? all of the above are correct - answerWhich of the following represent typical power steering pressures? over 750 psi when slowly maneuvering a parking lot about 450 psi when cornering less than 150 psi when straight ahead all of the above are correct True - answerA power steering pressure switch sends a signal to the powertrain control module, indicating higher engine speed is needed during sharp cornering at low speeds. True or False? Both technicians - answerTechnician A says that a leaking pressure relief valve can cause absence of power assist. Technician B says that a missing or slipping pump drive belt can cause lack of power assist. Which technician is correct? Technician A only Technician B only Both technicians Neither technician Technician A only - answerTechnician A says that some power assist systems use an external cooler for the power steering fluid. Technician B says that the cooler is located in the pressure line, before the steering gear. Which technician is correct? Technician A only Technician B only Both technicians Neither technician Technician B only - answerTechnician A says that all vehicles from the same manufacturer use exact same power steering fluid. Technician B says that some fluids may be incompatible with system seals. Which technician is correct? Technician A only Technician B only Both technicians Neither technician Both technicians - answerTechnician A says that lifting the vehicle and turning steering wheel may help bleed air out of some systems. Technician B says that if this procedure is used, the wheels should be turned from stop to stop. Which technician is correct? Technician A only Technician B only Both technicians Neither technician Technician B only - answerA power steering pressure gauge is being used to diagnose a system problem on a rack and pinion system. When the wheels are turned all the way left, a pressure reading less than specification is found. When the gauge valve is closed, the pressure reading is within specifications. Technician A says that the pump pressure regulator is bad. Technician B says that there is a problem in the rack assembly. Which technician is correct? Technician A only Technician B only Both technicians Neither technician Pascal's law - answerA power steering test is being performed, and the pressure is higher than specifications with the engine running and the steering wheel stationary in the straight ahead
