Schematic for pressure sensors
The boost pressure sensor and the engine oil
pressure sensor are active sensors.
The boost pressure sensor provides the ECM with a
measurement of inlet manifold pressure in order to
control the air/fuel ratio. This will reduce the engine
smoke during transient conditions.
The operating range of the boost pressure sensors
For standard power engines,
the range is up to the following. .................. 339 kPa
For all high power engine,
the range is up to the following. .................. 440 kPa
The engine oil pressure sensor provides the ECM
with a measurement of engine oil pressure. The ECM
can warn the operator of possible conditions that can
damage the engine. This includes the detection of
an oil filter that is blocked.
The operating range for the engine oil pressure
sensor ................ 55 kPa to 339 kPa (8 psi to 50 psi)
(49.169 psi)
