Technician A says that a diode is an electrical one-way check valve with no moving parts. Technician B says that a transistor is an electronic switch with no moving parts. Who is correct?
Technician A says that in a series circuit, the same current flows through each resistance. Technician B says an ammeter must be connected in series. Who is correct?
Technician Asays a shorted circuit can generate excessive heat. Technician B says a shorted circuit will cause the circuit protection device to open. Who is correct?
Technician A says that the DLC may be located under the hood on an OBD II vehicle. Technician B says that the DLC may be located anywhere that the manufacturer chooses on an OBD II vehicle. Who is correct?
Technician A says not all manufacturers provide freeze frame data.Technician B says one of the mandated features of OBD II is the inclusion of freeze frame data. Who is correct?
Technician A says that the DLC on an OBD II vehicle has 18 pins. Technician B says that the pin assignment for the DLC on an OBD II vehicle has not changed since 1996. Who is correct?
Technician A says that all P1XXX DTCs are for manufacturers' specific diagnostic trouble codes. Technician B says that all P0XXX DTCs are for generic diagnostic trouble codes. Who is correct?
Technician A says the learned LTFT corrections are used as a new base line for STFT. Technician B says the STFT values are constantly adjusted by the PCM to correct for rich/lean running conditions. Who is correct?
Technician A says the functional test observes the reaction of an output device to a command from the PCM. Technician B says with a scan tool you can access the Readiness Status menu to determine which monitors have run. Who is correct?
Technician A says the fuel system monitor may not be allowed to run if a pending code is stored. Technician B says the comprehensive component monitor will use one-trip logic when determining when to set a DTC and illuminate the MIL. Who is correct?
Technician A says the comprehensive component monitor is used to check devices that do not have their own monitor. Technician B says the comprehensive component monitor also checks the wiring for shorts and opens. Who is correct?
Technician A says a random misfire or a multiple cylinder misfire will be recorded as a P0300 code. Technician B says that a MIL that is flashing is an indication of an intermittent emission system failure that is not currently occurring. Who is correct?
Technician A says that the engine misfire monitor is a non-continuous monitor. Technician B says that the engine misfire monitor is a continuous monitor. Who is correct?
Technician A says the comprehensive component monitor will use three-trip logic when determining when to set a DTC and illuminate the MIL. Technician B says an OBD II system requires a drive cycle to occur that meets specific enable criteria before the monitors will run to completion. Who is correct?
Technician A says the comprehensive component monitor continues to run until all sensors have been tested once. Technician B says the rationality test checks to see if the input values from a sensor make sense, based on the current operating conditions at the time the test is performed. Who is correct?
Technician A says the heated oxygen sensor monitor performs two distinct tests; one test verifies the performance of the pre- and post-oxygen sensor heater element and circuit. Technician B says the heated oxygen sensor monitor performs two distinct tests; one test monitors the pre- and post-oxygen sensor signal switch rate and signal circuit. Who is correct?
Technician A says that a fuel-saturated evaporative emissions canister will cause negative STFT numbers. Technician B says that a fuel-saturated evaporative emissions canister will cause negative LTFT numbers. Who is correct? Group of answer choices
Technician A says the secondary air monitor tests for flow by monitoring the oxygen sensor response. Technician B says the secondary air monitor is run once per drive cycle. Who is correct?
Technician A says the catalyst's ability to store and release oxygen is a direct indication of the catalyst's performance. Technician B says the catalyst monitor compares the signal from both the upstream and downstream oxygen sensors. Who is correct?
