MIVEC (Mitsubishi Innovative Valve Electronic Control System)
M21302000235USA0000010000
ECM turns the engine oil control valve ON/OFF
according to engine speed in order to control oil pressure acting on the piston in the rocker arm. Thus,
change is done between low-speed cam and high-
speed cam.

Engine oil pressure switch
(for MIVEC)
ECM turns OFF (Duty: 0 %) the engine oil control
valve at low engine speed (4,750 r/min or less). As a
result, oil pressure does not act on the piston in the
rocker arm and inlet valve is driven by the low speed
cam. ECM turns ON (Duty: For 2 seconds after
change 100 %; after 2 seconds 60 %) the engine oil
control valve at high engine speed (4,750 r/min or more). As a result, oil pressure acts on the piston in
the rocker arm and inlet valve is driven by the high
speed cam. It will be continually driven by the low
speed cam under following conditions.
Engine coolant temperature is less than 20°C(68°
F).
For 10 seconds after engine is fully started.
