1.After the engine starts, the lAc valve opens for a certain time. The amount of air is increased to raise the idle speed
about 150 - 300 rpm.
When the coolant temperature is tow, the IAC valve is opened to obtain the proper fast idle speed. The amount of
bypassed air is thus controlled in relation to the engine coolant temperature'

lf the E position is selected while the veiicle is moving forward at speeds over 6 mph (10 km/h), the inhibitor solenoiddoesn't turn off by means of the TcM or PCM Reverse inhibitor pressure (Rl) is not applied to the reverse inhibitor valveas the reverse inhibitor solenoid turns on. The reverse inhibitor valve is kept on the right side, and covers the pon ro sropreverse brake pressure {RVS} to the reverse brake from the manual valve.
