Check for a worn universal joint. D. Check the backlash of the ring and pinion gear set. Answer   2. While diagnosing a front-wheel-drive car that makes a clunking noise when it is accelerating and making a turn, Technician A says an excessively worn throw-out or release bearing can cause this problem. Technician B says a worn CV-joint can cause this problem. Who is right? A. A only B. B only C. Both A and B D. Neither A nor B Answer (Top)   A4: Suspension & Steering 1. Technician A says that incorrect tire pressure can cause a vehicle to pull. Technician B says that incorrect toe and caster alignment settings can cause the vehicle to pull. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor B Answer   2. Which of these is not part of the normal procedure for replacing a front stabilizer bar? A. Remove from the frame mountings. B. Remove the outer connections at the control arms. C. Disconnect the tie-rod ends. D. Raise the vehicle on a drive-on hoist so that the tires evenly support the weight of the vehicle. Answer (Top) A5: Brakes 1. When repairing a damaged brake line, which of the following is correct? A. Replace the damaged section with a piece of tubing and compression fittings. B. Replace entire line that is damaged with a new line bent to the right shape using a tube bender. C. Repair the damaged section by cutting out that section and clamping a piece of high pressure hose to the line. D. Repair the damaged area by cutting out the damaged area and installing a fitting on the ends of the line. Then install a brake hose of the appropriate size. Answer   2. A car has an excessive amount of pedal travel during brake application, which of the following could be the cause? A. A stuck wheel cylinder piston. B. Excessive clearance between the shoe and drum. C. Worn brake pads. D. Incorrectly adjusted parking brake. Answer (Top) A6: Electrical/Electronic Systems 1. Technician A says a voltmeter can be used to measure the voltage in and out of a starter relay or solenoid. Technician B says that a jumper wire can be used to bypass the starter relay. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor B Answer   2. Which of these could be the cause of high current draw during starter motor operation? A. Excessive voltage drops across the negative battery cable. B. Low engine compression. C. Battery needs charging. D. Starter windings are open. Answer (Top)   A7: Heating & Air Conditioning 1. When conducting a pressure test on an A/C system, the ambient temperature is 85 degrees F., the low-side gauge reads very low (10 psi) and the high-side gauge also reads low (90 psi), which of the following could cause these readings? A. Low Refrigerant Level. B. Normal Operation. C. Bad Compressor. D. A high-side restriction. Answer   2. The heater of a car puts out very little heat, which of the following could cause the problem? A. Thermostat is stuck open. B. A defective cooling fan clutch. C. Heater control valve stuck open. D. Restricted airflow through the radiator. Answer (Top) A8: Engine Performance 1. The exhaust coming from a vehicle is black. Which of these is the most likely cause: A. An overly rich air/fuel mixture. B. Worn piston rings. C. An ignition problem. D. Blown head gasket. Answer   2. Technician A says that although all cylinders were in balance during a cylinder power test, there still may be a problem with the ignition or fuel systems. Technician B says that good cylinder power balance test results indicate that compression is good in all cylinders. Who is right? A. A only B. B only C. Both A and B D. Neither A nor B Answer (Top) L1: Advanced Engine Performance 1. At a steady speed of about 50 mph, a voltmeter placed on pin 53 indicates a voltage of 3.0 VDC. Technician A states that this indicates that approximately 50 Grams per second of air is being used by the engine. Technician B states that the voltage will drop if the vehicle is driven faster. Who is correct? A. A only B. B only C. Both A and B D. Neither A nor B Answer   2. Technician A says that exhaust restrictions can be identified by observing vacuum while the engine is running. Technician B says that exhaust restrictions can be identified by observing the pressure in the exhaust manifold with a low pressure gauge. Who is right? A. A only B. B only C. Both A and B D.
