ASE G1 Test Prep for 2022/23 Technician A says that when pressure testing a radiator cap, a special adapter is needed. Technician B says the best way to check thermostat operation is while it is in the engine. Who is right? ANS:- Tech A A technician is checking resistance in an engine's spark plug wires using an ohmmeter. A general rule is to replace a wire if resistance is over: ANS:- 30,000 ohms Technician A says that in an ignition system, the voltage supplied to the coil during starting is battery voltage. Technician B says the coil uses electromagnetic induction to create high voltage. Who is right? ANS:- Both techs A front wheel drive vehicle with an automatic transaxle has excessive vibration. Technician A says that the vibration could be caused by worn engine/transaxle mounts. Technician B says that the vibration could be caused by a misaligned engine/transaxle subframe. Who is right? ANS:- Both techs A technician suspects that a faulty camshaft sensor causes a driveability complaint. The sensor is equipped with a three-wire connector. What type of sensor is this? ANS:- a Hall effect type All of the following can cause a problem in the Hydro-boost system EXCEPT: A. loose power steering pump belt B. leaking power steering hoses C. low power steering pump pressure D. leaking check valve ANS:- D Technician A says that if a wire is getting too hot, it's a sign of higher-than-normal current flowing through. Technician B says the wire would heat up if some of the individual strands are broken inside the wire insulation. Who is right? ANS:- Both techs Technician A says electrical connectors can be disconnected with the ignition switch ON, as long as the technician is using a ground strap. Technician B says when welding on a vehicle, the technician needs to use a static wrist strap. Who is right? ANS:- Neither Technician A says the thermostat maintains maximum engine operating temperature. Technician B says if the engine continuously runs hot, install a cooler thermostat. Who is right? ANS:- Neither A vehicle equipped with a MacPherson strut suspension is in the repair shop for new tires and an alignment. The technician noticed that the vehicle has some play in the lift-side inner tie-rod. What should the technician tell the customer? A. It is not a problem that will affect alignment. B. He can align the front end, but the tie-rod should be replaced soon C. The inner tie-rod needs to be replaced before an alignment can be performed D. He can set the vehicle alignment to compensate for the play in the inner tie-rod ANS:- C. An engine is losing coolant, yet has no external leaks. Technician A says to run the engine and see if there is white smoke out of the exhaust. Technician B says to find out if the engine's emission system uses a catalytic converter before running the test above. Who is right? ANS:- both LED bulbs can remain effective for up to how long depending on the size of the bulb and the conditions to which the bulb is exposed? ANS:- 15000 hours All of the following should be performed during a preliminary transmission inspection EXCEPT: A. check transmission fluid level B. visually check wiring and electrical connections C. check the condition of the filter D. check for fluid leaks ANS:- C A smeary film on the windshield is an indication of: A. evaporator core leak B. water valve leak C. heater core leak D. restricted drain hose ANS:- C Technician A says that all power should be removed from a circuit before testing the circuit with an ammeter. Technician B says that all power should be removed from a circuit before testing the circuit with an ohmmeter. Who is right? ANS:- Tech B A rear wheel drive vehicle with a one-piece driveshaft has excessive driveshaft vibration during low speed acceleration. Which of the following is the MOST likely cause? A. binding U-joints B. excessive driveshaft runout C. driveshaft out of balance D. improper driveshaft angle ANS:- D When replacing an integral hub/bearing assembly on a front wheel drive vehicle, all of the following must be removed EXCEPT: A. brake rotor B. brake caliper C. steering knuckle D. wheel ANS:- C The warning light on a vehicle with an anti-lock brake system lights when the vehicle is started. When the vehicle is moving, the light stays on. Which of the following could be the cause? A. mis-adjusted wheel sensor B. bad air release solenoid C. blown fail-safe monitor fuse D. bad warning light relay ANS:- A. The driver of a vehicle with hydraulic brakes says the brake pedal is extremely hard when stopping. Technician A says the problem could be in the power assist system. Technician B says the problem is most likely a weak or broken brake shoe return spring. Who is right? ANS:- Tech A Technician A says that DOT 3 brake fluid has a higher boiling point than DOT 4 brake fluid. Tehcnician B says that DOT 5 brake fluid should not be used in a vehicle with ABS. Who is right? ANS:- Tech B Technician A says Diesel Exhaust Fluid (DEF) has no affect on vehicle performance. Technician B says a high-rate battery discharge test is the same as a load test. Who is right? ANS:- Tech B All of the following are procedures for removing air from a hydraulic system EXCEPT: A. bench bleeding B. power bleeding C. manual bleeding D. vacuum bleeding ANS:- A A vehicle is leaking hydraulic fluid from a brake line. Technician A says a short splice can be used to repair the line. Technician B says if the line has not drained the master cylinder, the system does not need to be bled. Who is right? ANS:- Neither A vehicle w/ hydraulic brakes has been diagnosed with contaminated brake fluid. Of the following, what would be the proper procedure in the repair process? A. Repair the system and manually bleed with fresh brake fluid. B. Repair the system and flush with fresh brake fluid C. Repair the system and top-off with fresh brake fluid. D. None of the above ANS:- B. Technician A says the pressure differential switch activates a light on the dash warning the driver of a brake fluid pressure loss. Technician B says the combination valve activates a light on the dash warning the driver of a brake fluid pressure loss. Who is right? ANS:- Both techs All of these could cause tire wear if not within manufacturer's specifications EXCEPT: A. Caster B. wheel balance C. toe-in D. Camber ANS:- A The ball joints on a MacPherson strut suspension are being replaced. Technician A says that the coil spring compressor should be installed before separating the control arm and spindle. Technician B says that the wheel alignment should be checked after the ball joints have been replaced. Who is right? ANS:- Tech B
