OIL PRESSURE ALERT SYSTEM
TECHNICAL FEATURES
SYSTEM DESCRIPTION
This model utilizes an oil pressure alert system with the EOP sensor, which detects the oil pressure linearly, instead of a
conventional system that uses two EOP switches (high pressure side/low pressure side).
This system enables more accurate control of pressure alert, depending on the engine speed and engine temperature, which
realizes an enhanced reliability of the whole system.
