In an EUI system what is the primary PCM output used to control fuel quantity?

Question

Quizplus · Accepted Answer

The primary PCM output used to control fuel quantity in an EUI system is the EUI control actuator. This actuator opens and closes the injector needle valve to regulate the amount of fuel injected into the combustion chamber. The other options listed (fuel transfer pump actuator, throttle position angle, variable capacitance sensors) are not directly responsible for controlling fuel quantity in an EUI system.
