DIAGNOSIS AND TESTINGÐENGINE OIL
PRESSURE
(1) Remove the engine oil pressure sensor and
install Oil Pressure Line and Gauge Tool C-3292 with
a suitable adapter.
(2) Start engine and warm to operating tempera-
ture.
(3) Record engine oil pressure and compare with
engine oil pressure chart.
CAUTION: If engine oil pressure is zero at idle, DO
NOT RUN THE ENGINE.
Engine Oil Pressure (MIN)
At Idle 103.4 kPa (15 psi)
At 2000 rpm 310.2 kPa (45 psi)
If minimum engine oil pressure is below these
ranges, (Refer to 9 - ENGINE - DIAGNOSIS AND
TESTING).
(4) Remove oil pressure gauge and install the oil
pressure sensor. Tighten the sensor to 16 N´m (144
in. lbs.) torque.
OIL
STANDARD PROCEDURE-ENGINE OIL LEVEL
CAUTION: Do not overfill crankcase with engine oil,
oil foaming and oil pressure loss can result.
To ensure proper lubrication of an engine, the
engine oil must be maintained at an acceptable level.
The acceptable oil level is in the SAFE RANGE on
the engine oil dipstick (Fig. 150).
Unless the engine has exhibited loss of oil pres-
sure, run the engine for about five minutes before
checking oil level. Checking engine oil level of a cold
engine is not accurate.
(1) Position vehicle on level surface.
(2) With engine OFF, allow approximately ten min-
utes for oil to settle to bottom of crankcase, remove
engine oil dipstick.
(3) Wipe dipstick clean.(4)
Replace dipstick and verify it is seated in the
tube.
(5) Remove dipstick, with handle held above the
tip, take oil level reading.
(6) Add oil only if level is below the SAFE RANGE
area on the dipstick.
(7) Replace dipstick
STANDARD PROCEDURE-ENGINE OIL SERVICE
WARNING: HOT OIL CAN CAUSE PERSONAL
INJURY.
NOTE: Change engine oil and filter at intervals
specified in the owner's manual.
(1) Operate the engine until the water tempera-
ture reaches 60ÉC (140ÉF). Shut the engine off.
(2) Use a container that can hold at least 14 liters
(15 quarts) to hold the used oil. Remove the oil drain
plug and drain the used engine oil into the container.
(3) Always check the condition of the used oil. This
can give you an indication of engine problems that
might exist.

eral minutes. Check for leaks at the filter and drain
plug.
(11) Stop engine. Wait several minutes to allow the
oil to drain back to the pan and check the level
again.
USED ENGINE OIL DISPOSAL Care should be
exercised when disposing of used engine oil after
it has been drained from a vehicle's engine.
OIL COOLER & LINES
CLEANING AND INSPECTION

nent. Inspect the oil drain plug and drain hole
threads. Inspect the oil pan sealing surface for
straightness. Repair any minor imperfections with a
ball-peen hammer. Do not attempt to repair an oil

OIL PRESSURE SENSOR/
SWITCH
DESCRIPTION
The 3±wire, solid-state oil pressure sensor is
installed into the oil pressure galley on the engine
block. It is located below and to the rear of the
Engine Control Module (ECM) (Fig. 154).
OPERATION
Operation of the oil pressure sensor on the
diesel engine is controlled by the Engine Con-
trol Module (ECM). The Powertrain Control
Module (PCM) does not have any control over
the sensor.The oil pressure sensor uses three circuits. They
are:
²A 5±volt power supply from the ECM
²A sensor ground through the ECM's sensor
return
²A signal to the ECM relating to engine oil pres-
sure
The oil pressure sensor has a 3±wire electrical
function very much like the Manifold Absolute Pres-
sure (MAP) sensor on the gasoline powered engine.
Meaning different pressures relate to different output
voltages.
A 5±volt supply is sent to the sensor from the ECM
to power up the sensor. The sensor returns a voltage
signal back to the ECM relating to engine oil pres-
sure. This signal is then transferred (bussed) to the
instrument panel on the CCD bus circuit to operate
the oil pressure gauge and the check gauges lamp.
Ground for the sensor is provided by the ECM
through a low-noise sensor return.
REMOVAL
(1) Disconnect the battery negative cables.
(2) Disconnect the oil pressure sensor connector
(Fig. 155).
(3) Using a suitable socket, remove the oil pres-
sure sensor from the block (counter-clockwise).

(2) Install the oil pressure sensor and tighten to 16
N´m (144 in. lbs.) torque.
(3) Connect the battery negative cables.
(4) Start engine and check for oil leaks at the sen-
sor.
OIL PUMP
REMOVAL
(1) Disconnect the battery negative cables.
(2) Remove fan/drive assembly (Refer to 7 - COOL-
ING/ENGINE/RADIATOR FAN - REMOVAL).
(3) Remove the accessory drive belt (Refer to 7 -
COOLING/ACCESSORY DRIVE/DRIVE BELTS -
REMOVAL).
(4) Remove the fan support/hub assembly.
(5) Remove crankshaft damper (Fig. 157) (Refer to
9 - ENGINE/ENGINE BLOCK/VIBRATION
DAMPER - REMOVAL).

(Refer to 9 - ENGINE/VALVE TIMING/GEAR HOUS-
ING COVER - REMOVAL).
(7) Remove the four mounting bolts and pull the
pump from the bore in the cylinder block (Fig. 159).
CLEANING
Clean all parts in solvent and dry with compressed
air. Clean the old sealer residue from the back of the
gear housing cover and front of the gear housing.
INSPECTION
Disassemble and inspect the oil pump as fol-
lows:
(1) Visually inspect the lube pump gears for chips,
cracks or excessive wear.
(2) Remove the back plate (Fig. 160).
(3) Mark TOP on the gerotor planetary using a felt
tip pen (Fig. 160).
(4) Remove the gerotor planetary (Fig. 160).
Inspect for excessive wear or damage. Inspect the
pump housing and gerotor drive for damaged and
excessive wear.
(5) Install the gerotor planetary in the original
position. The chamfer must be on the O.D. and down.

(6) Measure the tip clearance (Fig. 161). Maximum
clearance is 0.1778 mm (0.007 inch). If the oil pump
is out of limits, replace the pump.
(7) Measure the clearance of the gerotor drive/
gerotor planetary to port plate (Fig. 162). Maximum
clearance is 0.127 mm (0.005 inch). If the oil pump is
out of limits, replace the pump.
(8) Measure the clearance of the gerotor planetary
to the body bore (Fig. 163). Maximum clearance is
0.381 mm (0.015 inch). If the oil pump is out of lim-
its, replace the pump.
(9) Measure the gears backlash (Fig. 164). The
limits of a used pump is 0.075- 0.85 mm (0.0296-
0.0335 inch). If the backlash is out of limits, replace
the oil pump.
(10) Install the back plate.
INSTALLATION
(1) Lubricate the pump with clean engine oil. Fill-
ing the pump with clean engine oil during installa-
tion will help to prime the pump at engine start up.
(2) Verify the idler gear pin is installed in the
locating bore in the cylinder block.
(3) Install the pump (Fig. 159). Tighten the oil
pump mounting bolts in two steps, in the sequence
shown in (Fig. 165).
²Step 1ÐTighten to 5 N´m (44 in. lbs.) torque.
²Step 2ÐTighten to 24 N´m (18 ft. lbs.) torque.
(4) The back plate on the pump seats against the
bottom of the bore in the cylinder block. When the
pump is correctly installed, the flange on the pump
will not touch the cylinder block.
(5) Measure the idler gear to pump drive gear
backlash and the idler gear to crankshaft gear back-
lash (Fig. 166). The backlash should be 0.75- 0.85mm (0.0296-0.0335 inch). If the backlash is out of
limits, replace the oil pump.
(6) If the adjoining gear moves when you measure
the backlash, the reading will be incorrect.
