Astuator Replacement
1.Pull back the boot, and loosen the locknut. Then dis-
connect the cable from the bracket.
Disconnect the cable end from the actuator rod.
Disconnect the 4P connector from the actuator.
Disconnect the vacuum hosa from the vacuum tank.Pull out the vent hose.
Remove the three mounting bolts and the actuator
with the bracket.
CABTI aP CONNECTOR
lf necessary, disconnect the cable end from the link-age over the accelerator pedal, then turn the grom-
met 90' in the bulkhead, and remove the cable,
Install in the revers€ order of removal, and adjust
free play at the actuator rod after connecting thecable (see ne)d column).

Actuator Cable Adjustment
Check that the actuator cable operates smoothlywith no binding or sticking.
Stan the engine. Hold the engine at 3,000 rpm withno load (Afl'in N or E, M/T in neutral) untit theradiator fan comes on, then let it idle.
Measure the amount of movement of the actuato.rod until the cable pulls on the accelerator lever(engine speed starts to increase). Free Dlay shouldbe 11 t 1.0 mm (0.43 I 0.04 in).
LOCKNUT FREE PLAY: 11 1 1.0 mm
{o.i|:l r 0.oit in}
lf free play is not within specs, loosen the locknut,
and turn the adjusting nut as required.
NOTE: lf necessary. check the throttle cable freeplay (see section 11). then recheck the actuator rodfree play.
Retighten the locknut, and recheck the free play.

Gauges (cont'd)
- How the Gircuit 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 soeedometer drive circuits
receive pulses from 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
The tachometer drive circuit receives pulses from
the ignition control module (lCM) in the distributor
assembly or the ECM/PCM. The solid-state
lachometer then displays these pulses as engine
speed. For each 200 pulses per minute from the
ignition control modul€ (lCM) or the ECM/PCM, the
tachometer displays 100 RPM.
Engine Coolant Temperature 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 lield. The magnetic
field, controlled by the coolant temperature 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 field.
The 6ngine coolant temperature sending unit's
resistance varies from about 137 ohms at low
engine temperature to between 3H6 ohms at high
temperature (radiator fan running).
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.

Fuel Gauge (All except cX)
The fuel gauge has two intersecting coils wound
around a permanent magnet rotor. Voltage applied
to the coils, through tuse 25, generates a magnetic
field. The magnetic field, controlled by the fuel
gauge sending unit, causes the rotor to rotate and
the gauge needle to move. As the resislance in the
sending unit varies, current through the gauge coils
changes. The gauge needle moves toward the coil
with the strongest magnetic field.
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 off, the
gauge remains at the last reading until you turn the
ignition switch to ON (ll) or START (lll) again,
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
Fuel Gauge (GX)
The fuel 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 PCM,
causes the rotor to rotate and the gauge needle to
move. The PCM calculates the gas quantity in the
fuel tank by using the fuel pressure value detected
by the tuel tank pressure sensor and the fuel
temperature value detected by the fuel tank
temperalure sensor, and outputs the signal to the
gauge assembly. The gauge needle moves toward
the coil with the strongest magnetic field.
When you turn the ignition switch off , the gauge
remains at the last reading until you turn the ignition
switch to ON (ll) or START (lll) again. When the
PCM detects a malfunction with the fuel pressure or
temperature, or detects a gas leak, the PCM
reduces the fuel meter to 0.
Refer to the Service Manual GX Supplement
(Section 11 , Fuel and Emissions) for specific tests
or troubleshooting procedures.
