INSTALLATION
(1) Clean relief valve, spring and bore.
NOTE: Lubricate relief valve with clean engine oil
before installing.
(2) Install relief valve and spring into housing.
(3) Install new retainer cap until flush with seal-
ing surface.
(4) Install oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - INSTALLATION).
(5) Fill crankcase with proper oil to correct level.
OIL PRESSURE SWITCH
DESCRIPTION
The engine oil pressure switch is located on the
lower left front side of the engine. It screws into the
oil filter adapter. The normally closed switch provides
an input through a single wire to the low pressure
indicator light on the instrument cluster.
OPERATION
The oil pressure switch provides a ground for the
instrument cluster low oil pressure indicator light.
The switch receives oil pressure input from the
engine main oil gallery. When engine oil pressure is
greater than 27.5 Kpa (4 psi), the switch contacts
open, providing a open circuit to the low pressure
indicator light. For wiring circuits and diagnostic
information, (Refer to Appropriate Wiring/Diagnostic
Information).
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect electrical connector from switch.
(3) Remove oil pressure switch (Fig. 110).
INSTALLATION
(1) Install oil pressure switch. Torque oil pressure
switch to 23 N´m (200 in. lbs.) (Fig. 110).
(2) Connect electrical connector to switch.
(3) Lower the vehicle.
(4) Start engine and check for leaks.
(5) Check engine oil level. Adjust as necessary.
OIL PUMP
DESCRIPTION
The oil pump is located in the timing chain cover.
It is driven by the crankshaft.
REMOVAL
The oil pump is contained within the timing chain
cover housing (Fig. 111).
(1) Remove oil pan. (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - REMOVAL)
(2) Remove the timing chain cover. (Refer to 9 -
ENGINE/VALVE TIMING/TIMING BELT / CHAIN
COVER(S) - REMOVAL)
(3) Disassemble oil pump from timing chain cover.
(Refer to 9 - ENGINE/LUBRICATION/OIL PUMP -
DISASSEMBLY)
(4) Clean and Inspect oil pump components. (Refer
to 9 - ENGINE/LUBRICATION/OIL PUMP - CLEAN-
ING) (Refer to 9 - ENGINE/LUBRICATION/OIL

VEHICLE SPEED SIGNAL
The vehicle speed signal is taken from the Output
Speed Sensor. The TCM converts this signal into a
pulse per mile signal and sends it to the PCM. The
PCM, in turn, sends the vehicle speed message
across the communication bus to the BCM. The BCM
sends this signal to the Instrument Cluster to dis-
play vehicle speed to the driver. The vehicle speed
signal pulse is roughly 8000 pulses per mile.
REMOVAL
(1) Disconnect battery negative cable.
(2) Raise vehicle on hoist.
(3) Disconnect output speed sensor connector.
(4) Unscrew and remove output speed sensor (Fig.
325).
(5) Inspect speed sensor o-ring (Fig. 326) and
replace if necessary.
INSTALLATION
(1) Verify o-ring is installed into position (Fig.
326).
(2) Install and tighten input speed sensor to 27
N´m (20 ft. lbs.).
(3) Connect speed sensor connector.
(4) Connect battery negative cable.
