CRANKSHAFT POSITION SENSOR
This sensor measures the location in degrees of rotation of
the crankshaft. A 15° resolution exists between signals. The
signal is triggered by teeth on the outer surface of the fly-
wheel as they pass by the sensor. The sensor gives the ECM
the location of the crankshaft at a given point in time. The
ECM processes the information and uses it in many differ-
ent types of calculations. For example, the sensor can be
used for RPM, and it can also be used to determine the rate
of acceleration of the crankshaft.
CAMSHAFT POSITION SENSOR
This sensor tells the ECM which stroke the engine is on.
Because the 4-stroke engine operates on a 720° cycle, the
piston is at TDC twice per cycle - once on the exhaust
stroke and once on the compression stroke.
MANIFOLD ABSOLUTE PRESSURE
(MAP) SENSOR
This sensor measures pressure in the intake manifold when
the engine is running. The ECM uses this sensor to aid in
calculating the required fueling. For the base fuel map, the
5000 relies on the MAP sensor only for low throttle open-
ings. After a given throttle opening is reached, the ECM
switches to the TPS sensor for its main fuel map. The 9000
relies entirely on the MAP sensor and only uses the TPS for
its main fuel map if the MAP sensor should fail.
The ECM uses the MAP sensor for many other calcula-
tions, but the base fuel map is the main one.
WASTEGATE CONTROL VALVE
(9000)
The wastegate control valve adjusts the wastegate position
based on input from the ECM. The wastegate does not
require any input from the ECM to operate at base boost
levels. In areas of operation where the ECM will allow the
turbocharger to exceed base boost, the wastegate control
valve bleeds some of the pressure that would typically be
used to open the wastegate via the wastegate diaphragm
port on the turbocharger. By bleeding this pressure, the
wastegate is set at a lower opening thereby allowing more
exhaust gas to pass by the turbine increasing the boost
level.
KNOCK SENSOR
This sensor controls engine knock or detonation. The
knock sensor assesses structure borne noise (vibrations)
caused by rapid pressure rises (detonation) in either cyl-
inder and performs calibration adjustments to the neces-
sary cylinder via the ECM limiting damage to internal
engine components. Detonation can be caused by many
variables including poor fuel quality, lean operating con-
ditions, or modified engine components/systems.

INTRODUCTION
The Service Icon is controlled by the ECM. The icon
should illuminate each time the engine is started, and it
should go out after a few seconds. If the icon stays illu-
minated while the engine is running and a code is dis-
played on the readout screen, the ECM is receiving input
that is outside of its established parameters. Refer to the
following chart.
