A sequential fuel injection system uses a ________ to time the fuel injection pulses.
A) CMP sensor
B) throttle body sensor
C) MAP sensor
D) Spark sensor

Question

Quizplus · Accepted Answer

A sequential fuel injection system uses a camshaft position sensor (CMP) to determine the position of the engine's pistons and time the fuel injection pulses accordingly. This ensures that the fuel is delivered precisely when it's needed and in the right amount, which improves performance and fuel efficiency. Throttle body sensors, MAP sensors, and spark sensors are all important components in a fuel injection system, but they don't play a direct role in timing the fuel injection pulses in a sequential system.
