- How the Circuit Works
The low engine oil pressure indicator light works in
two ways: il flashes continuously following a
momentary loss of engine oil pressure, or it comes
on and stays on with a complete loss of engine oil
oressure,
When the engine first starts, before its oil pressure
rises above 4.3 psi, voltage is applied to the closed
and grounded engine oil pressure switch and the
light comes on to test the bulb.
With the engine running, voltage is applied at the
WHT/BLU wire of the integrated control unit. With
normal engine oil pressure, the engine oil pressure
switch is open and the low oil pressure indicator
light does not come on. lf the engine oil pressure
switch closes momentarily (more than 0.5 seconds)
but then opens again, the YEURED wire at the
integrated control unit will sense ground through the
switch. The integrated control unit will then provide
and remove ground for the low oil pressure indicator
light through the YEURED wire. The light will flash
on and off until you turn the ignition switch off. The
flashing feature will not work until 30 seconds after
initial voltage is applied to the WHT/BLU wire of the
oil pressure indrcator llasher circuit. This delay
keeps the low oil pressure indicator light from
coming on during engine warm-up.
lf engine oil pressure falls below 4.3 psi and does
not increase, the engine oil pressure switch will stay
closed. The low oil pressure indicator light will then
come on and stay on.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

- How the Circuit Works
When the ignition switch is in ON (ll) or START (lll),
battery voltage is supplied through fuse 25 to the
gauges in the gauge assembly.
Speedometer and Odometer
The odometer and speedometer drive circuits
receive pulses lrom the vehicle speed sensor
(VSS). The pulse rate increases as the car
accelerates. The frequency and duration of these
input pulses are measured and displayed by the
speedometer, odometer and tripmeter.
Tachometer ('98-'99 Models)
The tachometer drive circuit receives oulses from
the ignition control module (lCM) in the distributor
assembly. The solid-state tachometer then displays
these pulses as engine speed. For each 200 pulses
per minute from the ignition control module (lCM),
the tachometer displays 100 RPM.
Tachometer ('00 Model)
The tachometer drive circuit receives pulses f rom
the PCM or ECM. The solid-state tachometer then
displays these pulses as engine speed. For each
200 oulses oer minute trom the PCM or ECM the
tachometer displays 1 00 RPM.
Engine Coolant Temperature Gauge and Fuel
Gauge
The engine coolant temperature gauge has two
intersecting coils wound around a permanent
magnet rotor. Voltage applied to the coils, through
fuse 25, generates a magnetic field. The magnetic
field, controlled by the engine coolant temperature
gauge sending unit, causes the rotor to rotate and
the gauge needle to move. As the resistance in the
sending unit varies, current through the gauge coils
changes. The gauge needle moves toward the coil
with the strongest magnetic tield. The fuel gauge
works the same way.
The engine coolant temperature gauge sending
unit's resistance varies from about 137 ohms at low
engine temperature to between 30-46 ohms at high
temperature (radiator fan running).
The fuel gauge sending unit's resistance varies from
about 2-5 ohms at full, to about 110 ohms at empty.
When you turn the ignition switch to LOCK (0), the
gauge remains at the last reading until you turn lhe
ignition switch to ON (ll) or START (lll) again.
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
