Pressure Switches
Two positive pressure switches are located in front of body strut mount. One switch operates when intake manifold pressure reaches 1.0 psi and causes turbo indicator light to illuminate.
At the same time, it also transmits heavy load signal to the control unit for canceling air/fuel ratio feedback control. The other switch operates at a pressure of 9.1 psi and cuts off fuel when an abnormal rise in supercharging pressure occurs.
