         VEHICLE SPEED SENSOR

NOTE:    Vehicle speed sensor circuit test for Montero and 3000GT is

         not available from manufacturer at time of publication.

         Circuit Test (Eclipse, Galant & Mirage)

         1) Disconnect vehicle speed sensor harness connector. Turn

ignition on. Check voltage between ground and vehicle speed sensor

harness-side connector terminal No. 3 (Yellow/White wire on Eclipse 2.

0L Non-Turbo models and Galant, or Yellow wire on Eclipse 2.0L Turbo

and 2.4L models and Mirage). Voltmeter should read 4.5 volts or

greater. If voltage is as specified, go to step 4). If voltage is not

as specified, go to step 5).

         2) Check voltage between ground and vehicle speed sensor

harness-side connector terminal No. 1 (Yellow wire on Eclipse 2.0L

Non-Turbo models, Black/White wire on Eclipse 2.0L Turbo and 2.4L

models and Mirage, or Yellow/White wire on Galant). Voltmeter should

read battery voltage. If voltage is as specified, go to step 4). If

voltage is not as specified, go to step 5).

         3) Check continuity between ground and vehicle speed sensor

harness-side connector terminal No. 2 (Black/Green wire on Eclipse 2.

0L Non-Turbo models, or Black wire on Eclipse 2.0L Turbo and 2.4L

models, Galant and Mirage). If continuity is present, go to next step.

If continuity is not present, go to step 5).

         4) Check harness connector to instrument cluster. Repair as

necessary. If connector is okay, check circuit between vehicle speed

sensor and power supply. See WIRING DIAGRAMS. Repair as necessary.

         5) Check harness connectors to instrument cluster and vehicle

speed sensor. Repair as necessary. If connectors are okay, check

circuit between vehicle speed sensor and instrument cluster. See

WIRING DIAGRAMS. Repair as necessary.

         Circuit Test (Montero Sport)

         1) Disconnect vehicle speed sensor harness connector. Check

circuit between instrument cluster harness connector and ignition

switch. See WIRING DIAGRAMS. Repair as necessary. If circuit is okay,

go to next step.

         2) Remove instrument cluster. See  INSTRUMENT CLUSTER under

REMOVAL & INSTALLATION. Check continuity between ground and instrument

cluster harness-side connector terminal No. 31 (Black wire). See

WIRING DIAGRAMS. If continuity is present, problem is intermittent. If

continuity is not present, go to next step.

         3) Check circuit between instrument cluster and ignition

switch. See WIRING DIAGRAMS. Repair as necessary. If circuit is okay,

replace speedometer assembly.

         Sensor Test (All Models)

         1) Remove vehicle speed sensor from transaxle. Jumper a 3000-

10,000 ohm resistor between sensor terminals No. 1 and 3. Connect

battery positive to sensor terminal No. 1 and battery negative to

sensor terminal No. 2. See Fig. 29.

         2) Connect a voltmeter between sensor terminals No. 2 and 3.

Manually turn speed sensor shaft. Voltage should pulse 4 times each

revolution. Replace vehicle speed sensor if operation is not correct.

         VOLTMETER

         Circuit Test (Montero Sport Only)

         1) Remove multi-meter assembly from top of dashboard. Check

voltage between ground and multi-meter harness-side connector terminal

No. 10 (Red/Black wire). If voltage reading is about 12 volts, go to

step 4). If voltage reading is not about 12 volts, go to next step.

         2) Check harness connector to multi-meter assembly. Repair as

necessary. If connector is okay, check circuit between multi-meter

harness connector and fusible link No. 6. See  WIRING DIAGRAMS. Repair

as necessary. If circuit is okay, go to next step.

         3) Turn ignition on. Check voltage between ground and multi-

meter harness-side connector terminal No. 11 (Black/White wire). See

WIRING DIAGRAMS. If voltage reading is about 12 volts, problem is

intermittent. If voltage reading is not about 12 volts, go to next

step.

         4) Check harness connector to multi-meter assembly. Repair as

necessary. If connector is okay, check circuit between multi-meter

assembly harness connector and ignition switch. See  WIRING DIAGRAMS.

Repair as necessary. If circuit is okay, go to next step.

         5) Turn ignition off. Check continuity between ground and

multi-meter assembly harness-side connector terminal No. 3 (Black

wire). If continuity is present, problem is intermittent. If

continuity is not present, go to next step.

         6) Check harness connector to multi-meter assembly. Repair as

necessary. If connector is okay, check multi-meter assembly harness

connector ground circuit. See WIRING DIAGRAMS. Repair as necessary. If

circuit is okay, replace multi-meter assembly.

         Resistance Test (Montero Only)

         Using an ohmmeter, check resistance between voltmeter

terminals. See Fig. 30. Resistance should be 380-460 ohms.

         Voltage Test (3000GT Only)

         Start engine, and let it idle. Connect voltmeter to battery.

Compare voltage reading of test voltmeter to voltage reading of

vehicle voltmeter. Voltage variation should not exceed 0.5 volt (plus

or minus). Replace instrument cluster voltmeter if voltage reading is

not as specified.

         FOGLIGHT SWITCH TEST

NOTE:    Montero Sport is not equipped with foglights.

         Eclipse

         Remove foglight switch from instrument panel. Disconnect

switch connector. Using an ohmmeter, check switch continuity. With

switch in OFF position, continuity should exist between terminals No.

1 and 3. With switch in ON position, continuity should exist between

terminals No. 1 and 3, and between terminals No. 4 and 5. See  Fig. 31.

If continuity is not as specified, replace switch.

         Galant & Mirage

         Remove foglight switch from instrument panel. Disconnect

switch connector. Using an ohmmeter, check switch continuity. With

switch in OFF position, continuity should exist between terminals No.

1 and 2. With switch in ON position, continuity should exist between

terminals No. 1 and 2, terminals No. 3 and 4, and terminals No. 5 and

6. See Fig. 31. If continuity is not as specified, replace switch.
