FUEGO Turbo
The EGR valve opens the circuit as a result of intake manifold vacuum. The exhaust gas recirculation is possible only when the solenoid is energized. This is accomplished when 3 conditions are met:
- When 5th gear is not engaged, 5th gear switch is open.
- When coolant temperature exceeds 113°F (45°C), coolant temperature switch is closed.
- When pressure differential switch is electrically fed caused by vacuum effect in pressure surge valve during acceleration.
