A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct because Ford indeed eliminated the physical MAP (Manifold Absolute Pressure) sensor with the introduction of the EEC V (Electronic Engine Control, fifth generation) system, opting instead to infer manifold pressure through software algorithms and other sensor inputs.

C)initiating a KOEO self-test and check for resulting DTCs
D)using a scan tool to verify the Mode $06 data for the fuel trim monitor

Accepted Answer

After resetting the inertia switch, it is important to pressurize the fuel system and check for leaks to ensure there are no fuel system issues that could lead to safety hazards.

Question 5

A)GEM and the BCM
B)BCM and the ABCM
C)FEM and the REM
D)IPC and the MIC

Accepted Answer

Ford divided the Generic Electronic Module (GEM) into two separate modules: the Front Electronic Module (FEM) and the Rear Electronic Module (REM) starting with the 2002 model year for the Lincoln LS and the Ford Thunderbird.

Question 6

A)camshaft
B)crankshaft
C)distributor
D)DIS module

Accepted Answer

The CMP sensor on a two-valve-per-cylinder engine is typically a single Hall effect sensor activated by a vane driven by the camshaft.

Question 7

Technician A says adaptive strategy could also be called learning capacity. Technician B says adaptive strategy could also be called self-correction ability. Who is correct? ​
A)Technician A only
B)Technician B only
C)Both A and B
D)Neither A nor B

Accepted Answer

Both technicians are correct. Adaptive strategy refers to the ability of an organization to learn from its experiences and insights, and self-correct its functions and behavior accordingly.

Question 8

Which statement about the coil-per-plug (CPP)ignition system is correct?
A)The system uses a waste spark system.
B)The system uses four ignition coils on a V8 engine.
C)The PCM directly controls the coils.
D)The system uses an ignition control module.

Accepted Answer

The statement that the PCM directly controls the coils is correct for the coil-per-plug ignition system. The waste spark system is used in distributorless ignition systems, not CPP. While CPP may use four ignition coils on a V8 engine, this is not necessarily true for all engines using CPP. Some implementations of CPP may use an ignition control module, but it is not a defining characteristic of the system.

Question 9

A modern Ford vehicle equipped with Fail-Safe Cooling is being diagnosed. The customer says the engine runs rough and the temperature warning lamp is on. Technician A says that the PCM is disabling fuel injectors to keep the engine from overheating. Technician B says that if the temperature reaches 330 ° F, the engine will shut off. Who is correct?
A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

Accepted Answer

The answer of A modern Ford vehicle equipped with Fail-Safe...

Question 10

Which sensor produces the tach reference signal for the PCM?
A)The CHT sensor
B)The HEGO sensor
C)The CKP sensor
D)The IAT sensor

Accepted Answer

The CKP (crankshaft position) sensor produces the tach reference signal for the PCM (powertrain control module). The CHT (cylinder head temperature) sensor measures the temperature of the engine's cylinder head, the HEGO (heated oxygen) sensor measures the oxygen content in the exhaust, and the IAT (intake air temperature) sensor measures the temperature of the air entering the engine. None of these sensors produce the tach reference signal for the PCM.

Question 11

Which of the following was implemented by Ford with the EEC III high-pressure CFI system in 1980 and continued to be used through the 2009 model year?
A)The fuel pump
B)The ignition system
C)The PCM
D)The inertia switch

Accepted Answer

The inertia switch was implemented by Ford with the EEC III high-pressure CFI system in 1980 and continued to be used through the 2009 model year. This safety device is designed to cut off the fuel supply in the event of a collision to prevent fuel leakage and potential fires.

Question 12

What is the purpose of the fuel pressure regulator on a return-type fuel system?
A)To raise the fuel pressure when the intake vacuum increases
B)To maintain fuel pressure in the fuel tank
C)To maintain a constant fuel pressure drop across the fuel injectors
D)To maintain a constant fuel pressure in the fuel rail

Accepted Answer

The answer of What is the purpose of the fuel...

Question 13

Which component of the returnless fuel system is located outside of the fuel tank?
A)The fuel pump
B)The fuel screen
C)The fuel pressure relief valve
D)The fuel pump module

Accepted Answer

The fuel pump module is located outside of the fuel tank. It contains the fuel pump, fuel pressure regulator, and fuel level sensor.

Question 14

A downstream oxygen (O₂)sensor is reading the same as the upstream O₂ sensor. What does this indicate? A)The downstream sensor is defective and must be replaced. B)The converter has low efficiency. C)The upstream sensor is not working properly. D)The converter is working properly.

Accepted Answer

The downstream oxygen sensor reading the same as the upstream sensor typically indicates that the catalytic converter is not efficiently converting the exhaust gases, suggesting low converter efficiency.

A)Technician A
B)Technician B
C)Both A and B
D)Neither A nor B

Accepted Answer

Technician A is correct because a crankshaft position (CKP) sensor can indeed consist of a variable reluctance sensor, which generates an AC (alternating current) signal as opposed to a DC (direct current) voltage signal. Technician B is incorrect because CKP sensors typically do not produce a DC voltage signal directly.
