VACUUM PUMP
DESCRIPTION
The vacuum pump is operated by a slotted exten-
sion attached to the vacuum pump shaft. The vac-
uum pump shaft slotted extension fits into, and is
driven by, the exhaust camshaft gear.
The vacuum pump is a constant displacement,
vane-type pump. Vacuum is generated by vanes
mounted in the pump rotor. The rotor is located in
the pump housing and is pressed onto the pump
shaft.
The vacuum pump rotating components are inter-
nally lubricated.The vacuum pump is not serviceable and must be
replaced as a unit. Do not disassemble or attempt to
repair the pump.
OPERATION
Vacuum pump output is transmitted to the Heater,
Electronic, Vacuum, Air Conditioner (HEVAC) and
speed control, systems through a supply hose. The
hose is connected to an outlet port on the pump hous-
ing and uses an in-line check valve to retain system
vacuum when vehicle is not running.
Pump output ranges from a minimum of 8.5 to 25
inches vacuum.
The pump rotor and vanes are rotated by the pump
drive gear. The drive gear is operated by the exhaust
camshaft gear.
REMOVAL
(1) Disconnect negative battery cable.
(2) Remove vacuum line at vacuum pump (Fig.
44).
NOTE: Observe position of driver on rear of pump.
(3) Remove vacuum pump and seals (Fig. 44)
(4) Clean all sealing surfaces.

OIL TEMPERATURE SENSOR
DESCRIPTION
Oil level, oil temperature and oil quality are
detected by means of an oil sensor located in the oil
pan. The sensor which operates on the capacitance
principle features an integrated electronic circuit
which analyzes the three signals. the signals are con-
stantly relayed to the ECM and over the CAN bus to
the instrument cluster by means of PWM signal.
OPERATION
Oil quality is detected for indicating the need-
based oil change interval. The oil quality is detected
on the basis of the capacitance of the engine oil
(dielectrics, does not conduct electricity), this being
as much as six times greater in case of poor quality.

Oil level and oil quality are separate of each other.
The information is first of all compensated in the
ECM before being transmitted over the CAN bus.
Faults at the oil sensor are detected by the ECM
and entered into fault memory. The voltage for the
oil sensor (approx.5V) is supplied by the ECM.
