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.

2) ECT sensor resistance should be 90-117 ohms. If ECT sensor
resistance is okay, go to GAUGE RESISTANCE TEST. Replace ECT sensor if
resistance is not as specified.
Gauge Resistance Test
1) Remove instrument cluster. See INSTRUMENT CLUSTER under
REMOVAL & INSTALLATION. On 3000GT, remove air distribution duct and
combination gauges.
2) On all models, check resistance between temperature gauge

INTRODUCTION
NOTE: Unless stated otherwise in testing procedures, perform all
voltage tests using a Digital Volt-Ohmmeter (DVOM) with a
minimum 10-megohm input impedance. Voltage readings may vary
slightly due to battery condition or charging rate.
Pin voltage charts are supplied to reduce diagnostic time.
Checking pin voltages at the PCM connector determines whether it is
receiving and transmitting proper voltage signals. Diagnostic charts
may also help determine if PCM harness is shorted or open.
TEST PROCEDURE
CAUTION: Shorting positive DVOM lead between connector terminal and
ground could damage vehicle wiring, sensor and PCM.
1) If necessary, remove Powertrain Control Module (PCM) to
access harness connector. For PCM location, see PCM LOCATION table.
Leave PCM connectors connected.
2) Using DVOM, backprobe terminals. Connect positive DVOM
lead to appropriate PCM terminal. Connect negative DVOM lead to PCM
ground terminal. For PCM terminal identification, see appropriate
chart. See Figs. 1-24.
3) All measurements are applicable to vehicle at normal
operating temperature at sea level. Unless otherwise noted, engine is
idling when specification requires engine running. Ensure transmission
shift selector is in Neutral or Park (as applicable). If DVOM displays\
measurement that is not within specification, see G - TESTS W/CODES

allowing metal objects to contact the battery posts and the
vehicle at the same time.
CAUTION: Never disconnect the battery while the engine is running;
doing so could damage the car's electrical components.
REPLACING BLOWN FUSES
Before replacing a blown fuse, remove ignition key, turn off
all lights and accessories to avoid damaging the electrical system. Be
sure to use fuse with the correct indicated amperage rating. The use
of an incorrect amperage rating fuse may result in a dangerous
electrical system overload.
BRAKE PAD WEAR INDICATOR
Indicator will cause a squealing or scraping noise, warning
that brake pads need replacement.
BRAKE FLUID
WARNING: DO NOT use reclaimed fluid or fluid that has been stored
in old or open containers. It is essential that foreign
particles and other liquids are kept out of the brake fluid
reservoir.
CATALYTIC CONVERTER
Continued operation of vehicle with a severe malfunction
could cause converter to overheat, resulting in possible damage to
converter and vehicle.
ENGINE COOLANT SERVICE
WARNING: To avoid the danger of being scalded never change the coolant
when the engine is hot.
WARNING: Never remove the radiator cap when the engine is hot Serious
burns could be caused by high pressure fluid escaping from
the radiator.
CAUTION: When adding or replacing engine coolant, use a high quality
ethylene glycol antifreeze diluted with 50% distilled water.
When putting the cap on the reserve tank, line up the arrow
on the cap and the arrow on the tank, or coolant can leak out
ENGINE DRIVE BELT SERVICE
WARNING: Be sure the ignition key is OFF. The engine could rotate
unexpectedly.
ENGINE OIL
WARNING: The engine oil may be high enough to burn your fingers
when the drain plug is loosened. Wait until the drain plug
is cool enough to touch with you bare hands.
WARNING: Continuous contact with used engine oil has been found to
cause skin cancer in laboratory animals. Brief contact with
used engine oil may irritate skin. To minimize your exposure
to used oil, wear a long sleeve shirt and moisture-proof
gloves when changing oil. If oil contacts your skin, wash
