- Technician A says that a faulty radiator fan relay can cause an engine to overheat. Technician B says that bidirectional control is NOT used to test an electric cooling fan. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhile discussing SFI systems: Technician A says that when the injection system fires according to crankshaft position and speed, it is operating in the synchronous mode. Technician B says that one of the advantages of SFI systems is that they are always in the synchronous mode. Who is correct?arrow_forwardWhile discussing throttle-by-wire systems: Technician A says that a spring on the throttle shaft provides the limp-home feature. Technician B says that most systems have redundant processors and the TP and accelerator pedal sensors send redundant input signals. Who is correct?A. Tech A B. Tech B C. Both A and B D. Neither A nor Barrow_forward
- Technician A says that some systems use a special modulated shift control solenoid. Technician B says that some systems use a special modulated converter clutch control solenoid. Who is correct? Technician A says that shift solenoids direct fluid flow to and away from the apply devices in the transmission. Technician B says that shift solenoids are used to mechanically apply a friction brake or multiple-disc clutch assembly. Who is correct? Technician A says that throttle position is an important input in most electronic shift control systems. Technician B says that vehicle speed is an important input for most electronic shift control systems. Who is correct? Technician A says that a faulty TP sensor can cause delayed shifts. Technician B says that delayed shifts can be caused by an open shift solenoid. Who is correct? Technician A says that some shift solenoids can be activated by providing a ground for the solenoid. Technician B says that some shift solenoids can be activated by…arrow_forwardA 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_forwardTechnician A says that a malfunction of the ABS causes the control module to shut off or inhibit the system. Technician B says that a loss of hydraulic fluid or power booster pressure disables the antilock brake system. Who is correct? a.

Technician A only.Technician B only.Both A and B.Neither A nor Barrow_forwardTechnician A says that you may be able to smell antifreeze from a leaking heater core. Technician B says that you may be able to hear a loose belt when the engine is running. Who is correct? Select one: a. Technician A only b. Technician B only c. Both A and B d. Neither A nor Barrow_forwardWhen discussing the possible causes for a shudder during acceleration, Technician A says that a worn inner CV joint could be the cause. Technician B says that insufficient differential gear backlash could be the cause of the problem. Who is correct? O a. A only O b. B only O c. Both A and B O d. Neither A nor Barrow_forward
- An electronically controlled transmission has erratic shifting: Technician A says that a poor PCM ground will cause this problem. Technician B says that a bad AC generator-to-battery circuit will cause erratic performance of a transmission or transaxle. Who is correct?arrow_forwardTechnician A says throttle pressure is controlled directly by the pressure regulator valve. Technician B says one of the primary purposes of the pressure regulator valve is to fill the torque converter with fluid. Who is correct? a. A only b. B only c. Both A and B d. Neither A nor Barrow_forwardWhile diagnosing the cause of TCC shudder: Technician A checks the fluid pressure sent to the clutch. Technician B says that because the shudder occurs only after the clutch is engaged, the problem is the engine, transmission, or another component of the driveline. Who is correct?arrow_forward
