Sensors For Oil Pressure And Boost Pressure; Sensors For Water, Oil And Fuel Temperatures - Yanmar 6LY3 series Service Manual

ELECTRICAL AND ECU
Sensors for Oil Pressure and Boost
Pressure
The oil pressure sensor is located on the oil filter
bracket and the boost sensor is located on the
intake manifold.
An oil pressure switch is not used. Data from the oil
pressure sensor is used by the ECU for alarm
indication instead of an oil pressure switch.

Sensors for Water, Oil and Fuel
Temperatures
The water temperature sensor is located on the
exhaust manifold near the thermostat.
A water temperature switch is not used. Data from
the water temperature sensor is used by the ECU
for alarm indications instead of a water temperature
switch.
The oil temperature sensor is located on top of the
oil cooler. The fuel temperature sensor is located
on the side of the fuel injection pump
(Figure 12-17).
