INPUT/OUTPUT SENSOR

Eclipse 2.0L Non-Turbo With A/T

Disconnect sensor harness connector. Check resistance between

sensor terminals. Resistance should be 300-1200 ohms. Replace sensor

as necessary.

OIL PRESSURE GAUGE

Circuit Test (Eclipse, Montero & 3000GT)

1) Disconnect oil pressure gauge wiring connector from

sending unit inside engine compartment. Connect a 12-volt test light

between harness connector terminal and ground. Turn ignition on, but

DO NOT start engine.

2) If test light comes on and gauge needle moves, go to GAUGE

RESISTANCE TEST. If test light does not come on and gauge needle does

not move, repair wiring to sending unit.

Gauge Resistance Test (Eclipse, Montero & 3000GT)

1) Remove instrument cluster from instrument panel. See

INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. On 3000GT, remove air

distribution duct and combination gauges.

2) On all models, check continuity between oil pressure gauge

terminals. See Fig. 17, 18 or 19. See

OIL PRESSURE GAUGE RESISTANCE SPECIFICATIONS table. If resistance is

not within specification, replace oil pressure gauge.

NOTE: On Montero Sport, oil pressure gauge is mounted on

multi-meter assembly on center of dashboard.

Circuit Test (Montero Sport)

1) Disconnect harness connector from oil pressure sending

unit. Turn ignition on. Check voltage between ground and sending unit

harness-side connector. If battery voltage is present, problem is

intermittent. If battery voltage is not present, go to next step.

2) Check sending unit harness connector. Repair as necessary.

If connector is okay, check circuit (Yellow wire) between oil pressure

gauge and oil pressure sending unit. See WIRING DIAGRAMS. Repair as

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

3) Remove multi-meter assembly. Check voltage between ground

and harness-side connector terminal No. 10 (Red/Black wire). See

WIRING DIAGRAMS. If battery voltage is present, problem is

intermittent. If battery voltage is not present, go to next step.

4) 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.

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

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

WIRING DIAGRAMS. If battery voltage is present, problem is

intermittent. If battery voltage is not present, go to next step.

6) 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.

7) 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.

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

necessary. If connector is okay, check circuit (Black wire) between

multi-meter assembly harness connector and ground. See WIRING DIAGRAMS

. Repair as necessary. If circuit is okay, problem is intermittent.

Gauge Sending Unit Resistance Test (Montero Sport)

Disconnect harness connector to oil pressure sending unit.

Start and idle engine. Check resistance between oil pressure gauge

sending unit terminal and engine block. Resistance should be about 2

ohms. Replace sending unit if resistance is not as specified.

REED SWITCH

Continuity Check (Montero)

1) Remove instrument cluster. See INSTRUMENT CLUSTER under

REMOVAL & INSTALLATION. Check continuity between reed switch terminals

No. 1 and 2. See Fig. 20.

2) Ensure continuity pulses on and off 4 times per revolution

of speedometer shaft connection. If continuity is not as specified,

replace reed switch.
