"TORQUE CUT CONTROL (AT HIGH ENGINE OIL TEMPERATURE) The ECM receives engine oil temperature signals from engine oil temperature sensor. To avoid VVEL performance degradation, the ECM performs the engine torque cut control at high engine oil temperatures. If engine oil temperature is too high, engine oil viscosity will change. As a result, engine oil pressure is decreased. This control affects the VVEL operating angle by operating the VVEL actuator sub assembly. If this control is operated, engine performance will decrease, then maximum engine speed is reduced a bit (Various levels of Limp Mode depending on temp).
