- A discussion concerning CV joint testing is being held. Technician A says that a recommended method to check CV joints is to raise the vehícle so that the lower control arms are hanging freely; at this point the engine can be accelerated while noise checks can be performed. Technician B says that the vehicle should be road tested so that the CV joints can be checked under load. Who is correct? O a. A only O b. B only c. Both A and B d. Neither A nor Barrow_forwardAutomotive cooling system problems are being discussed. Technician A states that engine overheating is a common failure. Technician B states that an engine remaining below proper engine operating temperature is a common failure. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor Barrow_forwardA vehicle has had several radiator replacements, and each time there has been pinhole leaks in the aluminum. Technician A states that the engine coolant may need to be exchanged more often. Technician B states that the engine grounds should be inspected closely since this could be the cause. Who is correct? Select one: a. Technician A only b. Technician B only c. Both Technicians A and B d. Neither Technician A nor Barrow_forward
- Technician A says if the amber ABS warning light is on continuously, the ABS system is still operational but may not be operating at 100 percent efficiency. Technician B says ABS operation might be affected by improperly turning the drums and rotors. Who is correct? a. A only b. B only c. both A and B d. neither A nor Barrow_forwardCarbon deposits on the intake valve or seat may cause the valve not to close properly. Tech a says that the flywheel will be harder to spin when starting the engine. Tech b says that the engine will loose power. Who is correct?arrow_forwardTechnician A says that an EGR valve that is stuck open can cause idle problems. Technician B says that a stuck closed EGR can increase HC emissions. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- While discussing injector testing: Technician A says that a defective injector may cause cylinder misfiring at idle speed. Technician B says that restricted injector tips may result in acceleration stumbles. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhich of the following statements regarding the “Pre-Emission Inspection Check” Of a diesel powered vehicle that is subject to Opacity (Smoke Meter) testing is not true? The governor (if equipped), the exhaust system, and the emissions control devices must all be checked. The exhaust system must be checked for any missing sections which would prevent collection of a valid exhaust sample. Vehicles not meeting requirements cannot be inspected. This is not considered an inspection or rejection and no fee is to be charged. The governor, if originally equipped, must be checked for presence, connection, and operation.arrow_forwardTechnician A says that broken engine mounts can cause the fan to hit the shroud. Technician B says that missing or broken air dams can cause an engine to overheat. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forward
- HC emissions may come from the tailpipe or sources.arrow_forwardTechnician A says that if an engine had good results from a compression test, it will have good results from a cylinder leakage test Technician B says that if an engine had good results from a cylinder leakage test, it will have good results from a running compression test Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward120) Technician A says that RWD transmission valve bodies are serviceable from under the vehicle. Technician B says that most FWD transmission valve bodies are serviceable from under the hood. Which technician is correct? Technician A O Technician B Both technicians A and B O Neither technician A nor Barrow_forward
