While discussing the MIL on OBD II systems:
Technician A says that the MIL will flash if the
PCM detects a fault that would damage the
catalytic converter. Technician B says that
whenever the PCM has detected a fault, it will
turn on the MIL. Who is correct?
a. Technician A
• Technician B
• Both A and B
• Neither A nor B
Technician A says that the PCM illuminates the mil if a defective causes emission levels to exceed 2.5 times the emission standards for that model year vehicle. Technician B says that if a misfire condition threatens engine or catalyst damage, the PCM flashes the mil. Who is correct

The neutral safety switch and reverse lamp switch are typically part of a digital transmission range sensor.arrow_forwardWhich of the following is not a common emission control system? EGR PCV EVAP Air injectionarrow_forwardWhen testing an engine temperature sensor: Technician A uses an ohmmeter to test the thermistor. Technician B says that the thermistor reacts to pressure and applies air pressure to the backside of the sensor. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- True or False? The signals from an air-fuel ratio sensor are identical to those from a conventional oxygen sensor.arrow_forwardWhile discussing evaporative (EVAP) systems: Technician A says that the coolant temperature has to be above a preset value before the PCM will operate the canister purge solenoid.
