The EEC has how many control channels?

• A. Two
• B. Four
• C. One
• D. Three

Answer: (A)

The question tests redundancy in the engine electronic control system. The EEC is designed with two independent control paths, so there are two control channels that monitor sensors and drive actuators in parallel. They continuously compare outputs, and if one channel detects a fault, the remaining healthy channel can take over, keeping engine control safe. This hot-standby, dual-channel setup provides fault tolerance without requiring complex or excessive hardware. Two channels are enough to offer reliable backup and fault detection; having only one would remove redundancy and risk loss of control, while three or four would add unnecessary complexity for the same safety goal.
